    Description: This is the Report of 1996 survey of Trout Beck with particular reference to spawning gravel quality and invertebrates as a food source for salmonids produced by the Environment Agency North West. Whilst the main River Derwent is quite a high profile salmon fishery, Trout Beck is not a significant fishery in its own right, but serves to maintain the genetic integrity of the wild populations of trout and salmon in the catchment by providing a unique habitat. This survey addressed the invertebrate food availability, and additionally looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Description: This is the River Lynher Salmon Action Plan Final document produced by the Environment Agency in 1999. This final Salmon Action Plan (SAP) for the River Lynher catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The River Lynher salmon stock has suffered two periods of spawning target failure within the past ten years. This assessment can only be estimated and in this case is likely to be dependent on river flow and the availability of salmon to the rods as only rod catch is used in the compliance assessment.

    Description: This is the River Tavy Salmon Action Plan Final document produced by the Environment Agency in 2000. This final Salmon Action Plan (SAP) for the River Tavy catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Tavy salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Tavy.

    Description: This is the River Plym Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Plym catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. These issues and actions follow on from the detailed analysis of the catchment, which is presented in the River Plym SAP Consultation document.The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the River Plym SAP therefore, is to maintain, improve and develop the River Plym salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. The River Plym has failed to pass its conservation limit since 1996, and the consultees felt very strongly that there were three major factors limiting the salmon stock of the River Plym.

    Description: This is the report on the strategic stock assessment survey of the Colton Beck catchment in 1994 with particular reference to salmonids in Colton Beck, River Ea, River Gilpin and Rusland Pool. This report forms one part of the third year of a triennial survey programme for the South West Cumbria and South Cumbria catchments. It was produced by the National Rivers Authority in 1994. Colton Beck had excellent densities of sea trout (Salmo trutta) and a small population of salmon (Salmo salar) in its lowest reaches. The total productivity was very good throughout the catchment. Stocking of sea trout fry in 1993 has enhanced the population with survivors through to parr probably adding to the scoring of double class A at two sites in the survey in 1994. Stocking was not undertaken in 1994, but the population appears to be maintaining itself at a very high level.

    Description: This is the River Camel Salmon Action Plan produced by the Environment Agency in 2002. The report focuses on the River Camel Salmon Action Plan (SAP). The River Camel SAP follows the format of those completed for the Rivers Tamar, Lynher and Tavy. It is the 4th of 7 action plans that will be produced for salmon rivers managed by the Cornwall Area Fisheries, Recreation and Biodiversity Team. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. In addition, for the first time, Salmon Action Plans have attempted to evaluate in economic terms, all of the contributory components of the salmon fishery. The River Camel Salmon Action Plan contains a description of the river catchment and highlights particular features that are relevant to the salmon population and associated fishery.

The River Fowey SAP follows the format of those completed for the Rivers Tamar, Lynher, Tavy and Camel. It is the 5th of 7 action plans that will be produced for salmon rivers managed by the Cornwall Area Fisheries, Recreation and Biodiversity Team. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Fowey SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably, there are historic workings for copper and china clay and two significant potable supply reservoirs (Siblyback and Colliford) which have been constructed within the catchment during the past 35 years. The whole of the Fowey catchment is set at the highest water quality grading of RE1 and this standard is met in all reaches of the River Fowey and its tributaries.

    Description: This is the Gunnislake Fish Counter, Annual Report 1999 produced by the Environment Agency South West Region on March 2000. The report presents the daily upstream counts of migratory salmonids recorded at Gunnislake Weir fish counting station (SX 435 713) situated on the River Tamar in 1999. The counter data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the implementation of the National Spring Salmon Byelaws. The fish counter at Gunnislake is a resistivity based system (Logie 2100A – Aquantic limited) and is installed in the fish pass on the Cornish bank of the River Tamar at the head of the tide. The minimum salmon count for 1999 was 2691. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. However, the total combined annual count of salmon and sea trout migrating upstream on the River Tamar in 1999 was 25% higher than the 5 year average (1994 - 1998).

    Description: This is the Restormel Fish Counter, Annual Report 2001 produced by the Environment Agency South West Region on March 2002. The report presents the daily upstream counts of migratory salmonids on the River Fowey at Restormel Weir fish counting station (SX 107 613) in 2001. The counter data covers the period of the commercial salmonid net buy back scheme and the national spring salmon byelaws. These reduce the commercial netting season for salmon and sea trout to between 16 June and 31 August. The fish counter at Restormel is installed on a crump sectioned weir on the River Fowey. The fish counter is a resistivity based system and operates over all three channels of the weir. 2001 was a good year for large sea trout. The number of returning large sea trout was above average in April, May, June and July and equal to or higher than the previous recorded maximum in those months. The main run of small sea trout occurred at a similar time to previous years with the highest numbers of fish entering the Fowey during June and July.

    Description: This is the Restormel Fish Counter, Annual Report 2007 produced by the Environment Agency South West Region on March 2008. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel Weir fish counting station (SX 107 613) over the period March 2007 to February 2008 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (2 March- 15 June). The minimum upstream salmon estimate for 2007, over the period July 2007 to February 2008, was 796, which is the fifth highest recorded count over the past 13 years. The number of returning salmon in 2007 suggests a downward trend in numbers since 2004. The 2007 large sea trout count is similar to 2006. Overall, the number of fish returning is still low in comparison with the 10-year average. There was a noticeable decrease in the number of small sea trout returning compared to 2006 and the 10-year average. The Fish counter at Restormel suffered several faults.

    Description: This is the Restormel Fish Counter, Annual Report 2006 produced by the Environment Agency South West Region on March 2007. The report presents the upstream counts of migratory salmonids recorded on the River Fowey at Restormel weir fish counting station (SX 107 613) over the period March 2006 to February 2007 inclusive. Data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the National Spring Salmon Byelaws (2 March- 15 June inclusive). The minimum upstream salmon estimate for 2005 (1046), over the period July 2005 to February 2006, was 20% lower than that recorded over the same period in 2004 (1301). However, this is the second highest count recorded over the past 11 years. The total sea trout count (10448) was 8% higher than 2004 (9608). The number of salmon and large sea trout was lower than average in 2005. However, the overall numbers of adult salmon and sea trout returning have been increasing year on year since 1997. This overall increase in the salmon and sea trout counts, together with the consistency of the numbers of fish returning over recent years suggests that measures designed to protect salmonid stocks in the River Fowey are working.

    Description: This is the River Fowey Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Fowey catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Fowey salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the Fowey SAP therefore, is to maintain, improve and develop the Fowey salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. Although the Fowey is passing its conservation limit, the consultees felt very strongly that there were two major factors limiting the salmon stock of the River Fowey- the overgrazing of Bodmin Moor and the use of the catchment for water supply by South West Water.

    Description: This is the River Lynher Salmon Action Plan Consultation document produced by the Environment Agency in 1998. The report pays attention on the external consultation of the River Lynher Salmon Action Plan (SAP). The River Lynher SAP follows that for the River Tamar and is the second of seven action plans that will be produced for salmon rivers managed by the Cornwall area fisheries department. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Lynher SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The analysis of recent and historical catches of salmon on the River Lynher from both the rod and net fisheries indicated the fishery's reliance upon post 1 June salmon. Historically, annual salmon catches (both rod and net) on the River Lynher have been found to consist of a much higher proportion of pre 1 June (spring) salmon. Evidence is provided that illustrates the extent of the decline within this stock component since the early 1980s.

    Description: This is the Restormel Fish Counter, Annual Report 1999 produced by the Environment Agency South West Region on March 2000. The report presents the daily upstream counts of migratory salmonids recorded at Restormel Weir counting station (SX 107 613) River Fowey in 1999. The counter data covers the period of the commercial migratory salmonid net buy-back scheme, which was in operation between March and June 1999. The fish counter is a resistivity based system (Logie 2100 A - Aquantic limited) and operates over all three channels of the weir at Restormel. The minimum salmon count estimate was 497, and the 1999 upstream count for sea trout was 6590. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. Flows on average were half those of 1998 during September, October, and November.

    Description: This is the Wetland resource evaluation and the NRA's role in its conservation: Resource assessment report produced by North West Water in 1982. In this report data from a variety of sources in river Leven and Leven estuary have been examined to determine if there was any objective foundation for the allegations and for the assertion that poor fish catches were related to discharges of industrial effluent to the estuary. Catches of salmon and sea trout from the Leven did not appear to have suffered any long term declines and year to year fluctuations did not appear to be any more extreme than in other North West rivers. Fish surveys did not show any marked differences in the diversity or distribution of fish between the Kent and Leven estuaries but catches of flounders were consistently lower from the Leven estuary. Analysis of fisheries statistics of landings of fish and shellfish from Morecambe Bay did not show any evidence of localised declines in catches from the Leven estuary. Results of laboratory experiments suggested that populations of bivalve molluscs might be more at risk from the effects of discharges to the Leven estuary than resident or migratory fish.

    Description: This is the River Yealm Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Yealm catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Yealm salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. The main objective of the River Yealm SAP is to maintain, improve and develop the River Yealm salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support.

    Description: Twenty samples of canned seafood consisting of tuna, mackerel, sardines, prawn and shrimp were collected from retail operations in Victoria Island, Lagos, Nigeria. Mercury content in these canned seafood were determined after digestion by the Association of Official Analytical Chemists methods. The mercury contents for all the canned seafood products have concentrations well below the permissible EU levels for this toxic metal. Their contribution to the body burden can therefore be considered negligible and the canned seafood products seem to be safe for human consumption.

    Description: There have been many outcries in the Nigerian media on the various environmental degradation of the vast water space in the Niger Delta area of Nigeria by oil explorers. About 70% of the Nigerian populace lives in the coastal areas where the occupation is predominantly fishing and farming. For most of the publications, the extents of impact on the fishing industry are not addressed in order for solutions to be given. Production from the fisheries sector has dropped astronomically thereby earning the country a deficit due to importation of frozen fish to the country. In this study, a survey of three states (Bayelsa, Rivers and Delta) in the Niger Delta area of Nigeria was done. The communities studied include Ogulagha, Okobelema and Okpoama. Personal interviews with fishermen and primary data on the sector’s contribution to fish production and GDP were also carried out. The study aimed at finding out the sources and nature of degradation and the impacts such have on the fishing industry and the socio-economics of the fishermen. The study revealed that there are no significant difference in the negative impacts of environmental degradation caused by the activities of the oil companies on the socio-economics of the fishermen ((F2,27=0.59, P〉0.05)) The difference is not significant and the hypothesis is therefore accepted. The major impact on fishing was depletion in catches and low income earnings by fishermen with a resultant poor quality of living and livelihood. Oil spills, foreign vessels incursions and bunkering, vandalization of pipelines were identified sources of depletion in fish catches from the wild. The personal interviews and Focus Group Discussion (FGDs) showed that most heads of communities rely on the remuneration they get from the companies and refused to mobilize the fishermen for joint action against the oil companies. Mitigation measures usually carried out by the oil companies do not actually replenish the destroyed mangroves where breeding of fishes take place. The communities need the Government to institute high level surveillance of the high seas and monitor the activities of oil explorers as well as education of the communities on the effects of bunkering near shoreline.

    Description: This study was carried out to determine the bioaccumulation of heavy metals in Clarias anguillaris and Parachanna africana from Lake Geriyo Yola, Nigeria using energy dispersive X-ray fluorescence (EDXRF) spectrophotometer. The results in (mg/kg, dry weight) showed different levels of Cr, Cu, Mn, Fe, Ni, Zn, and Pb in the two fish species. The order of heavy metals accumulated by C. anguillaris and P. africana are Cr〉Fe〉Zn 〉 Mn〉Cu〉Ni〉Pb and Ni〉Fe〉Zn〉Cu respectively. The levels of Cr, Mn and Ni in C. anguillaris and in Ni in P. africana were higher than WHO and FEPA recommended maximum permissible limits (MPL) in fish, while the levels of Zn, Cu and Pb were below the standards. The results suggest that Lake Geriyo has high pollution loads of these heavy metals in fishes and could pose a health hazards to man. Consequently, close monitoring of heavy metal loads in Lake Geriyo is recommended with a view to minimizing the risks to health of the population that depend on the lake for their water and fish supply.

    Description: Investigation of the microbiological purity of Lake Kivu as index of water pollution was carried out in Gisenyi, Kibuye and Cyangugu over a period of 24 months. Microbial load did not differ significantly with season and locations but Fecal Coliform (FC) had positive significant correlation (r = 0.36; p〈0.05) with season. Mean Total Coliform (TC) (cfu/100ml) was highest 7.7 x 105 in Gisenyi and lowest 1.7 x 105 at Cyangugu. These values exceeded the 5000 colony forming units/100ml recommended by WHO for public surface water supplies. Total heterotrophic bacterial (THB), FC, TC and Fecal streptococcus (FS) were widespread with abnormally high values in the sampling locations signifying poor water quality. Microbial isolates from the water samples were of wide range of groups and their occurrence and distribution varied from location to location. Bacillus sp, E. coli, Citrobacter freundii, Klebsiella pneumonia and Proteus sp were the cosmopolitan microbial species in the lake water. The microbial quality of the water was poor rendering it unsafe for domestic purposes without treatment and this was largely caused by direct contamination of the lake by animals and human domestic wastes.

    Description: Static bioassays were carried out in the laboratory for 96h to investigate the effect of Parateq a synthetic base mud on the fingerling of Orechromis niloticus and their microbial population. The fingerlings were exposed to different concentrations (0, 1000, 3000, 5000 and 9000Mg/l) of drilling fluid. Fish mortality data were recorded at 24, 48, 72 and 96h and analysed using Finney’s Probit Analysis method to calculate LC50 values (concentration of drilling fluid in water that will kill 50% of the fish population in 96 hours). The 96h LC50 was 2210Mg/l.The mortality increased with increase in concentration, while, the lethal times decreased as concentration increased. The bacterial biomass ranged from 1.59 x 108 to 6.0 x 106CFU/ml while fungal biomass ranged from1.0 x 103 to 2.1 x 104 CFU/ml. Results revealed that there was an increase in fungal biomass with increase in mud concentration and a decrease in bacterial biomass with increase in mud concentration.

    Description: The physical and chemical parameters of ABU Dam and Zaria Dam were carried out between September and October 2009. The results obtained in the two water bodies were temperature 27.7 0C, pH (7.5 and 7.3), dissolved oxygen (5.8 mg/l and 5.0 mg/l), biochemical oxygen demand (1.74 mg/l and 2. 16 mg/l), alkalinity (58 mg CaC03/l and 49 mgCaCO3/l) P04-P (2.47 mg/l and 1.59 mg/l) NO3-N (3.67 mg/l and 3.47 mg/l), conductivity (54.70 ~ks-1 and 42.48 ~ks-1), total hydrocarbon (TH) (47.66 mg/l) and 48.00 mg/l) and total dissolved solids (32.68 mg/l and 25.35 mg/l) respectively. There was no significant difference in the mean values of the parameters (P〉0.05) except conductivity and total dissolved solids. The water bodies were found to be neutral with high conductivity. All the properties in the water bodies were in conformity with international standards both for drinking and aquatic life.

    Description: A static bioassay method to determine the acute toxicity of the herbicide propanil to Oreochromis niloticus was investigated under Laboratory conditions for 96 hours exposure period. Concentrations of propanil used include: 0.0096ml/l, 0.0103ml/l, 0.011ml/l and 0.012ml/l respectively. The lethal concentration (LC50) value of propanil on fingerlings of Oreochromis niloticus was 0.0097ml/l for 96 hours of exposure. The regression equation for probit kill from propanil was found to be Y = 29.84 + 12.33* log conc. (r2 0.9951, Y = Probit kill). Fish showed various abnormal behaviours upon exposure to propanil. Immediate reaction was erratic swimming and tendency to jump out of the test bowl. Others include: restlessness, un-coordinated movement, vertical swimming, air gulping, equilibrium loss, a period of quiescence and eventually death.

    Description: The concentration of heavy metals: Lead (Pb), Cadmium (Cd), Iron (Fe) and Zinc (Zn) in tissues of fin fish from a tidal fish farm in Calabar, South East Nigeria, was determined. The mean levels of heavy metals (~kgg-1) in gills, muscle tissues, liver and intestines of catfish were Pb: 2.39~c1.24; Cd: 0.87~c0.83; Fe: 3.96~c1.55; Zn: 8.15~c3.18. Mean levels in Tilapia were Pb: 0.035~c0.002; Cd: 0.61~c0.05; Fe: 1.09~c0.61; Zn: 2.17~c0.53. There was no significant difference (p〈0.05) in tissue concentrations of Pb and Cd whereas a significant difference (p〈0.05) was observed between Pb and Zn concentrations for both species of fish. Concentrations were also higher in liver, gills and muscle tissues than the intestines. Highest concentrations were observed in the liver and gills in both species. Generally, higher concentrations were observed in liver, gills and muscles of Catfish than in Tilapia. Concentrations of Pb and Fe in Catfish were significantly higher (p〈0.05) than the WHO limits, while Zn and Cd were lower. Tissue concentrations of all the metals in Tilapia were however, within the WHO recommended limits. The concentrations in all the fish tissues were significantly higher (p〈0.05) than in the surrounding water. The observed values in Catfish indicate environmental threat to the health of the fish and indeed the humans that consume them and therefore calls for environmental surveillance in the area

    Description: Spatial and temporal variations of physico-chemical variables of Onu-Iyi ?Ukwu stream were studied for 12 months from March 2005 to February 2006. Three sampling stations were established along the main stream channel from source to mouth. Spatial variation in physico-chemical parameters indicated that total alkalinity, total hardness, conductivity, and nitrate-nitrogen (NO3) recorded their highest values at the upper reaches (with values 14.0mg/l, 88.09mg/l, 17.00~kscmiscm, and 0.60mg/l respectively). Dissolved Oxygen (DO) and pH had their maximum values of 8.20mg/l and 6.94 at the middle reaches. Turbidity, biochemical oxygen demand (BOD), temperature and phosphate-phosphorus (PO4) increased steadily from source to mouth. The observed seasonal variation indicated that wet season values were higher for all the parameters except temperature, turbidity, phosphate-phosphorus (PO4) and total alkalinity although the values were not statistically significant at p〉0.05. The correlation coefficient (r) showed no significant relationships p〈0.05 between physico-chemical parameters except DO and BOD with correlation values of (0.75 and -0.54) respectively.

    Description: The poor nature of most Agricultural processing practices in Nigeria have had adverse effect on our environment, and our aquatic resources are of no exception. This study was conducted to ascertain the median lethal concentration of the effluent within the 96 hours period and also to ascertain the extent of damage on some of the histological characteristics of the Clarias gariepinus juveniles. Juveniles of the Clarias gariepinus (mean weight 30g) were exposed to varied concentrations of the locust bean effluent under the standard laboratory conditions. Data on mortality corresponding to the various concentrations were subjected to the probit and logit transformations and used to calculate the LC50 graphically. The result shows the toxicity of the locust bean effluent to Clarias gariepinus juveniles as 0.089mg/L (treatment 4) during the period of study. Exposure to both the acute and subletheal concentrations resulted in a number of physiological dysfunction of the test fish. Observation of the fish under the tests revealed unbalanced swimming patterns loss of reflex, rapid opercular movements and gasping for air. Histopathological examination of the gill and liver of the treated fish showed signs of damage, ranging from Hypoxia, lesions, necrosis, fibrosis cell stasis and hyperplasia at the sublethal levels.

    Description: The physico-chemical parameters of Bosso Dam were analyzed weekly for a period of six (6) weeks from 29th October, 2009. In all, six (6) stations were identified within the dam. The physico-chemical parameters assessed were: temperature, dissolved oxygen, pH, alkalinity, hardness, conductivity and transparency. The results obtained from the analysis revealed slight variations in most parameters. There was no significant difference p〉0.05 in pH regardless of stations and weeks. But significant difference p〉0.05 were observed in dissolved oxygen, nitrate, temperature, conductivity, hardness, alkalinity, biological oxygen demand, transparency, in respect regard to stations. These variations could be due to influx of organic waste from surface run offs and inorganic waste deposited by man. The physico-chemical parameters observed, indicated that most of them fall with the recommended range or standard by the Federal Ministry of Environment

    Description: The design of pumping station for submersible FLYGT pump 3102 version LL to redress the water supply problem of some ponds in the tidal fish farm of African Regional Aquaculture Centre (ARAC) located in Omuihuechi, Aluu, Rivers State, Nigeria was carried out. Prior to the design baseline study was carried out for the proper sitting of the pumping station. The topographic survey of the area indicated gentle sloping woodland, with the highest and lowest elevations of 11.00 m and 1.00 m respectively. The mean peak heights of water in the supply canal during spring and neap tides ranged from 0.95 to 1.45 m and 0.38 to 0.86 m respectively. The flood tide and ebb tide velocities of supply canal water flow varied from 0.40 to 0.75 m/s and 0.75 to 0.92 m/s respectively. Soil particle size analysis indicated loamy clay and clay soils. The results of pumping station design were 1.80 m (length), 1.30 m (width); 3.60 m (height),0.15 m (thickness), I (cement) : 2 (sand) : 4 (gravel) (concrete mixture ratio) and 12 mm (reinforcement bar). Results of pump characteristic calculation were 0.069 m〈sup〉3〈/sup〉/s (discharge) ,4.02 m/s (pumping velocity), 5.73 m (total dynamic head), 0.82 m (minimum submergence depth), 5.04 KW (pump power)and 0.40 and 0.30 m ( clearances from floor and wall respectively). The results obtained were considered adequate for the purpose of construction of the pumping station for the pump and the procedures adopted will assist in similar design tasks in the development of fish farms in the Niger Delta Region of Nigeria and beyond.

    Description: This paper reviews some adverse effects of crude oil pollution on fish and fisheries in Nigerian waters. The main causes of spillage include blowout, sabotage, corrosion of pipeline, equipment malfunction, operations/maintenance error etc. There are spillage records from 1976 to 1997 with respect to the yearly oil spill incidents, the sizes of spill in relation to the ecological operational areas and the causes of oil spills in relation to sources of oil spill within oil operation. Based on the observation from the analyses of the spillage reports, several steps were recommended in order to reduce the incident of crude oil spillage in Nigeria petroleum industry for the safety of our fragile water bodies and the fisheries resources stock in them.

    Description: The effect of zinc exposure evaluated during a four day exposure periods at 13.88ppm, 26.75ppm, 53.5ppm,107ppm and 214ppm to Clarias gariepinus sub-adults showed the 96h LC50 as 26.62ppm. The threshold value was 20.30ppm. The muscle of the exposed fish analyzed showed a significant decrease in all the major cations and anions (Na+, CL-, Ca2+ K+, Mg2+) at (p〈0.05). The research revealed that there was no total inhibition of uptake of the cations and anions and also that uptake of these metals, that is cations and anions (Na+,-CL-, Ca2+ K+, Mg2+) increased rapidly during the 24 hours and dropped at 48 hours and 72 hours and gradually increased at the end of 96 hours showing that it was time dependent. During exposure period, affected fish stood in upright position with their snouts above the water surface, gasping for air. Observation of the exposed fish showed that they were peeling of skin, increase in opercula movement, erratic swimming, quietness and finally death. This research therefore recommends that zinc should be applied appropriately at 26.30ppm to avoid death of fish, man and other aquatic organisms that are the chief consumer.

    Description: Climate change has the potential to severely impact coastal and inland environments and ecosystems, and by extension fisheries and aquaculture. Coastal regions of the world are already experiencing flooding due to rise in sea level. In recent times, salinization of coastal areas due to flooding from storm surges and high tidal influence has been observed. Aquaculture is a fast growing agri-business venture in Nigeria presently and many coastal communities derive their livelihood from it. The culture of freshwater fish species that are very sensitive to high salinity may be threatened leading to mortality of stocked fish and loss of livelihood for coastal population. Consequently, there is urgent need for development and domestication of the Silver catfish, Chrysichthys nigrodigitatus that can tolerate higher salinity more than Mudcatfish (Clarias gariepinus). This will help mitigate the impact of salinization of coastal areas arising from sea water flooding on culture of fresh water fish species.

    Description: The effects of Goldcrew, a chemical dispersant commonly used in crude oil spill incident, to alter interactions between the components of the crude and the biota in the ecosystem, were studied. We used a static renewal bioassay to study its effects on Bonny light crude using the tilapia, 0. niloticus at various concentrations for 50 days. A control experiment was also set up. The exposure concentration of the water accommodated fractions (WAF) of the mixture of the dispersant and Bonny Light crude, dispersed crude (DCOWAF-PAH) and the WAF of Bonny Light alone (COWAF-FIH) were 0.2,0.4,0.8 and 1.6m/L respectively. The mortalities of the fingerlings in different concentrations of the DCOWAF-PAH were 66.7%, 23.3%, 86.75% and 100% in the 0.2. 0.4, 0.8 and 1.6m/L exposure centrations respectively. At these concentrations, mortality was significantly different (P〈0.05) between the fingergerlings and fry, with a total mortality of 69.2% among the fingerlings, while the fry had 5.8% mortality in the 0.8 and 1.6ml/L concentrations with 13.3% 10.0% respectively but the differences were not statistically significant (p〈0.05). There was no mortality in the concentrations of COWAF- PAH. It can be said that Bonny Light was made more toxic to 0. niloticus by the presence of the dispersant; increased the susceptibility of the fingerlings to the mixture of crude and dispersant and influenced the behavior of the fish. There is therefore need to apply dispersants with caution especially around fish breeding and nursery ground.

    Description: Fingerlings of Ciarias gariepinus were exposed to various sublethal concentrations (10.0, 20.0, 30.0. 40.0, 50.0 and 60.0 ~KL/L) formalin and the concentration of 0.0 ~KL/L formalin served as the control. The toxicant led to depressed weight gain in the fish. Severity of this depression was directly proportional to the toxicant concentrations. However, there was no difference (p〉0.05) in weight gain in test fish of various concentrations. Restlessness, loss of balance, erratic swimming behavior, respiratory distress, vertical movement and death, were observed in test media especially in the concentrations 60.0 and 50.0~Kl/L of formalin. Such observation were not recorded in the control tanks.

    Description: The sub-lethal effect of glyphosate on behavior and some biochemical parameters of African catfish, Clarias gariepinus were investigated using static renewal bioassays and continuous aeration for a period of 28 days using varying concentrations (100ppm, 200ppm, 300ppm, 400ppm and 500ppm). During the exposure period, the fish showed different abnormal behaviours such as restlessness, loss of balance, respiratory distress, grouping together, darting movements, loss of equilibrium, mucous secretion and erratic swimming. At the end of the experiments, the fish were sacrificed and the blood samples were collected. The gill and liver of the fish were removed from biochemical bioassay. Compared with the control, the result showed a significant increase (P〈0.05) in the activities of alanine amino transferase (ALT), and aspartate amino transferase (AST), in both the blood and the gill of exposed fish except in liver where it showed a significant reduction. However the values of lactate dehydrogenase (LDH) and superoxide dismutase (SOD), showed significant increase in the blood with a noticeable decrease in both the gill and liver of exposed fish. The study showed that sub-lethal concentratiom of glyphosate are harmful to Clarias gariepinus. This study shows that sub-lethal concentrations of glyphosate is harmful to Claria gariepinus. The implication of these results in rational exploitation and conservation of fishery resources and the public health risk consuming glyphosate-exposed to fish are highlighted.

    Description: The impact of anthropogenic activities on chemical and nutrient characteristics of selected wetlands in Moyamba and Bo districts was investigated. Water and sediments samples for nutrient and trace metal analysis were collected for two seasons (wet and dry) at sampling sites. Anthropogenic activities such as industrial effuent, domestic and agricultural waste disposal constitute major sources of wetland pollution in the selected districts. Samples of water and soil were analyzed for metals (Cr, Co, Cd, Ni, Pb, Mg, Mn, Fe, C1 and Zn) and nutrients (Ca, K, P and Na) levels were determined and their seasonal variations were compared at (p〉0.05) significant levels. Physico-chemical parameters such as Temperature, Dissolved oxygen, Ammonia, Nitrate, pH, general hardness, total alkalinity were also measured. Fe was the most concentrated metal in water (mean range 15.93 ~c 1.51 to 33.65 ~c 7.79mg/l) and in sediment (15748 ~c 3526 to 107702 ~c 84038 mg/1), while Cr and Mg were the least concentrated (0.34 ~c 0.14 to 0.53 ~c 0.09mg/l) and (0.07 ~c 0.01 to 0.22 ~c 08 mg/1) respectively. Generally, trace meta levels in sediment of the study area were relatively higher than tht concentration in water. Na was the most concentrated nutrient in both water and sediment, while calcium has the least. Calcium plays an important role in blood clotting, muscular contractions and in some enzymatic processes and as such its level in the studied wetland must be augmented. Accumulations of metals in the environmental matrices are ecologically undesirable as they pose threats to man who is the end user of the values of wetland ecosystems and consequently the need for policy intervention in the effective management of both domestic and industrial wastes.

    Description: The study identified the perception of fish farmers in Oyo State to climate change as well as the adaptation strategies used by them. A two stage stratified sampling method was used to select 156 fish farmers from the four Agriculture Development Programme (ADP) zones and eight local government areas (LGAs) in Oyo State. Structured questionnaires were administered to the fish farmers. Descriptive statistic and linear regression were used to analyses data collected. The result shows that majority were males (84.0%\}, dominant age (66.0%) were within the age bracket of 46-65 years. The farmers are literate as 46.8% have attained secondary education, 69.9% had above six years of experience in fish farming experience and 97.5% were engaged in culturing catfish Clarias spp. The highest portion (70.5%) earns less than N500,000 as income from fish sale. Due to effect of climate change on fish production in the study area, fish farmers reported different types of adaptation strategies. Result of the linear regression analysis indicates that there is a significant (p〈0.05) negative effect of household size and years of fish farming experience and significant (p〈0.1) positive effect of age on farmers' perception of climate change on fish production.

    Description: The acute toxicity and the effect of sub-lethal concentrations of calcium carbonate on the morphology of M. macrobrachion were investigated under laboratory conditions. The prawns were exposed at 0, 160, 320, 640, 1280, 2560 and 5120 mg/l of CaCO3 using static renewal bioassay for 96 hours for the acute toxicity test. The prawns were also exposed for the chronic test at 0, 20.0, 40.0, and 80.0 mg/1 for a period of two weeks. Mortality occurred in the bioassay tanks at random and the bioassays were monitored throughout the exposure period. Results showed that exposed prawns were not significantly impacted when compared with the control group and correlations were significant at P〈0.05. There were no mortalities in the tanks with the highest concentrations while one death was recorded in the control tank and in the tank with the 160 and 320mg/1 of CaCO3 respectively. The gills of exposed prawns were analyzed using photomicrography and the results showed that the organs had their normal morphological status after the exposure time, implying that CaCO3 is non-toxic to M. macrobrachion. The applications of the result to prawn culture and water quality management were discussed in details.

    Description: This study was conducted to determine the effects of dichlorvos ~9 2, 2 - dichlorovinyl dimethyl phosphate (DDVP)~0 on the growth of Clarias gariepinus fingerlings. The experiment was conducted in two phases: the first phase involved the exposure of the fish to different concentrations ~9 0.00 (control), 0.4ppm, 0.5ppm, 0.6ppm, 0.7ppm, 0.8ppm, 0.9ppm, 1.0ppm, 1.1 ppm and 1.2ppm~0 of dichlorvos for four days. The second phase was a recovery process in which the fish that survived from the first phase were introduced into clean, dechlorinated, toxicant-free water and were fed at 3% of their body weight for 12 weeks. The change in weight was measured every fortnight and the feed fed was adjusted to accommodate the change in weight. The highest values for weight gain, percentage weight gain, specific growth rate and average daily weight gain occurred in the control and these values were significantly (p〈0.05) higher than the values of these parameters recorded in the other treatments. The range of values of weight gain, percentage weight gain, specific growth rate and average daily weight gain are 6.76 ~c 3.01-18.45 ~c 8.90g, 69.45 ~c 18.52 - 105.52 ~c 33.67%, 1.54 ~c 0.33 - 2.08 ~c 0.46%/day and 0.48 ~c 0.21 - 1.21 ~c 0.65g respectively. Based on the results of this study, the exposure of fingerlings of Clarias gariepinus to dichlorvos ~9 2, 2- dichlorovinyl dimethyl phosphate (DDVP)~0 affected the growth of the fish. Therefore, the use of dichlorvos on stored grains should be regulated because uncontrolled usage could cause mortality and impairment of growth in fish if the pesticide gets washed into water bodies inhabited by fish.

    Description: The study investigated the acute toxicity of 2, 3-dicholrovinyl dimethyl phosphate (Sniper 1000EC) on the African mud catfish, Clarias gariepinus juveniles (mean weight 19.47 ~c 1.05g) using static bioassay method. Sniper 1000EC is an organophosphate pesticide. Each treatment in the acute test was in triplicate with bioassay media concentration of 0,5, 10, 15 and 20 mg/l. Data on mortalities of fish, water physic-chemical parameters as well as changes in haematological indices were subjected to one way analysis of variance (ANOVA) at 5% probability level. Duncan multiple range test was used to separate differences between the means. The 96hr LC50 estimated by probit analysis during the exposure was found to be 8.20mg/l. Behavioural abnormalities of the exposed fish included erratic and uncoordinated swimming and bleached skin with lesion at the highest concentration (20mg/l). Blood dyscrasias attributable to the toxicant was observed with a significant (p〈0.05) decrease in haemoglobin, haematocrit, red blood cells, white blood cells, lymphocytes and monocytes. Mean corpuscular volume (MCV), Mean corpuscular haemoglobin (MCH), neutrophils, eosinophil and basophil increased significantly (p〈0.05) with increasing concentrations of the toxicant. These abnormalities in body and blood parameters as a result of exposure to the toxicant make the study to recommend that the use of Sniper 1000EC by local fishermen be banned to preserve aquatic lives in Nigerian inland water bodies.

    Description: One of the priority research projects of the Nigerian Institute for Oceanography and Marine Research (NIOMR) is broodstock development and mass propagation of silver catfish, Chrysichthys nigrodigitatus of which the broodstock is naturally abundant in New Gala River. Selected physical characteristics and water physico-chemical parameters of the upper reach of the New Calabar River at Aluu were investigated. The highest depth value of 9.20 m was recorded in the middle of the river. The width of the river measured during spring high tide and low tide were 174 m and 110 m respectively. The cross-sectional area and average flow velocity of the river were 797.13 m2 and 0.374 m/s respectively. The discharge of the river was computed as 298.13m3/s. The river water was acidic most of the period (Hydrogen ion concentration, pH: 5.12 to 7.43), with low total alkalinity values (4.00 to 12.00 mgCaCO3/L) and low total hardness values (11.5 to 51.2 mgCaCO3/L) which indicate that the river water is black and soft. There was significant (p~,0.05) seasonal variation in temperature (23.1 to 31.7~'C\}, Secchi transparency (9.30 to 19.00 cm), total hardness (11.5 to 51.2 mgCaCO3/L), dissolved oxygen (5.20 to 7.50 mg/L) and dissolved oxygen deficit (0.02 to 2.95mg/L). These results are useful for several stake holders who use the river as a sink for trade wastes, as source of water for fish farming, as source of broodstocks of Chrysichthys nigrodigitatus, as raw water for water treatment plants, and as means of transportation of industrial materials.

    Description: Mechanization of agriculture to promote and improve the yields from agricultural practices has necessitated the use of pesticides and other agrochemicals. The effects of using these pesticides on the environment are rarely considered by farmers. This study investigated the effects and sub-lethal effect of atrazine on tilapia, an ubiquitous culturable fish species. The 96 hr LC50 was determined using static renewal bioassay method while the effect on haematological parameters was determined after exposure for 3 weeks to sub-lethal doses of atrasine. The LC50 was found to be 6.977mg/l. Sub-lethal exposure resulted in anaemia and increased the white blood cell counts.

    Description: The study examined fisher folk responses to climate change in Kainji lake basin. The sample comprises of fisher folks within and New Bussa. Eighty questionnaires were administered to obtain the primary data and analysed using descriptive and inferential statistical tools. The results revealed that majority (70%) of the respondent were male, however (61.2%) of them had tertiary education. Majority (60%) of the respondents were aware of changes in climate in the area. Majority (65%) and (55%) of the respondents were involved in incidence of deforestation and charcoal production respectively. In conclusion, it was discovered that little knowledge about climate change and its effects were found among fisher folk. Therefore it recommends that sensitization workshops/lectures be done to enable the fisher folk have adequate knowledge on climate change and the implications on fisheries activities in the basin.

    Description: Fish growth is a function of adequate supply of feed in the right quantity and time. The effect of feeding rate on the growth of Clarias gariepinus (Burchell, 1822) was studied for a period of 22 weeks. The fish were fed at the same percentage body weight throughout the study period and a bi-weekly weight gain was measured. Water quality parameters were also monitored. There was a significant increase in weight gain in daily feeding regime than in the ones in two days feeding regime. The increase in weight for the daily feeding regime was visible as from the 8th week while that for the ones in two days feeding was only significantly different in 22nd week at 0.05 level of significance. The relationship between the two feeding regime types also revealed that the daily feeding performed better than the ones in two days feeding regime.

    Description: Jabi Lake is a natural water body in Abuja Federal Capital Territory (FCT). It was expanded for commercial fishing following relocation of Nigeria's headquarters to Abuja in 1993. Quantitative analysis of microbiological status of water and fish from the Lake was carried out. Samples were collected from the dam site, open water, middle lake and inlet. Result reveal that total coliform count which are indicators of pollution are high (2.0 x 103 cfu/ml, 1.1 x 103 cfu/ml, 1.0 x 103 cfu/ml and 1.1 x 103 cfu/ml for dam site, open water, middle lake, and inlet respectively). Total viable count too is high (9.2 x 103 cfu/ml, 4.9 x 103 cfu/ml, 4.6 x 103 cfu/ml and 4.9 x 103 cfu/ml for dam site, open water, middle lake and inlet respectively). There are no coliform bacteria in the muscle of the fish. High bacterial load is an indication of biological pollution and these calls for restraint on the side of those who are using the lake as site for refuse dump.

    Description: This study assessed the physico-chemical parameters and heavy metal concentration of tap and borehole water in Minna metropolis. The experiment lasted over a period of three months from May to July 2012. Six (6) locations were identified within Minna metropolis, Bosso, Kpagungu, Chanchaga, Mobil, Maitumbi, and Tunga where water samples were randomly taken once every month. Hydrogen ions concentration, chloride, Sodium and Potassium were determined by the method of American Public Health Association (1995), while temperature was measured with thermometer. Air and Water temperature were determined in situ, while Hyd rogen ions concenration (pH), Ionic conductivity, Alkalinity, Hardness, Chloride, Sodium, Potassium and Heavy Metal concentration, copper, zinc, and Lead were determined in the laboratory. The parameters measured showed marked variation across months and locations. values of physico-chemical and concentration of heavy metals in Tap and Borehole water variables studied showed that parameter measured, fell within the recommended ranges for aquaculture and drinking water. Water temperature showed significant difference (p〈0.05), while conductivity, hardness, alkalinity, sodium and potassium showed no significant difference (p〉0.05) amongst the months. The physico-chemical parameters assessed, indicated that most of the parameters fell within standards set by the Federal Ministry of Environment. Comparison between tap and borehole water of each location in Minna metropolis did not show significant difference in temperatures of the locations (p〉0.05). However, significant difference was observed in conductivity of the various locations (p〈0.05).

    Description: Over the years, man has exploited the ocean and its resources for sustainable livelihood. Man's indigenous and traditional knowledge has been the mainstay and guidance in exploiting the ocean and coastal resources. However, as industrialization and other climate conditions set in to alter or modify the productivity of the ecosystem, there has been a lot of concern by international, regional and local authorities to continuously study the prevalence of these factors and triggers off these climatic changes and their impacts on livelihood of fisherfolks at the industrial or artisanal level of fishing and other fisheries activities like fish farming and fish processing. A quantum of technical and scientific information on the ocean and interactions with other elements have been archived in various libraries, information centers and on the internet. These channels provide information for only those who can access them for policy formulation but cannot actually reach those who will benefit or implement the issues discussed in the policy documents for their livelihood. Meteorological data are reported in technical terms. Figures and other illustrations cannot be utilized by the average artisanal and industrial fishermen for the rational exploitation of the ocean resources. The woman fish processor who uses solar dryer may not be able to relate the weather condition and why her fish cannot dry at the normal time. There are times natural phenomenon like change in the direction of or its intensity can be interpreted by a fisherman as the handwork of his enemy to thwart his fishing effort for that day. Oceans sourge causes and its possible displacement of coastal dwellers might not be fully comprehended by those living in coastal communities. There is the need therefore to develope a communication and outreach strategies using a simple communication matrix for easy articulation of approaches to communicating with all potential and identified stakeholders in Climate change and its effects on stakeholders. This paper therefore discusses some of the climatic conditions and factors that affects the ocean, coastal areas and their productivity. It particularly focuses on communication strategies of information, educating and entertaining in reaching out to identified stakeholders on climate impacts for its rational exploitation and improved income for better standard of living. It finally produced a simple applicable communication matrix for reaching out to all stakeholders in Climale change and its impacts.

    Description: The effect of acute toxicity of chicken droppings to fingerlings of Oreochromis niloticus was determined under laboratory conditions using static bioassay for a period of 96 hours. The 96-hrs LC50 was estimated to be 2.19 with upper and lower confident limits of 3.24 and 1.48g/l. Water quality examination revealed a reduction in the level of dissolved oxygen, increase in alkalinity and free carbon dioxide with increase in concentrations of the fertilizer while there were no significant different (P〉0.05) in the ievels of pH and temperature when compared with the control. Fish exposed to higher concentrations of the organic fertilizer became darker in colour with mucous secretion, exhibited erratic swimming and showed signs of respiratory distress before death. Methods and standard doses for subsequent organic fertilizer application in fish ponds for survival and growth are discussed.

    Description: This study investigated the levels of lead (Pb), cadmium (Cd), Copper (Cu), Chromium (Cr) and Zinc (Zn) in two common edible fish species, Sole, Solea solea and Croaker, Pseudotolithus typus from Makoko and Koko in Lagos and Delta states respectively. Heavy metal contents were determined by air-acetylene flame Atomic Absorption Spectrophotometer after wet digestion of dried and milled samples with 1:1 HN0〈sub〉3〈/sub〉: H〈sub〉2〈/sub〉O〈sub〉2〈/sub〉. Results obtained (~kg/g, dry weight) for Sole in Lagos and Delta states were: Pb (0.330 and 0.149), Cd (0.097 and 0.063), Cu (0.869 and 0.434), Cr (1.184 and 0.826), Zn (7.612 and 7.890); and Croaker: Pb (0.163 and 0.045), Cd (0.115 and 0.029), Cu (0.990 and 0.694), Cr (1.008 and 1.038) and Zn (6.756 and 6.168) for the wet season (April-October); and Pb (0.534 and 0.527), Cd (0.373 and 0.410), Cu (0.437 and 0.556), Cr (0.834 and 0.983), Zn (6.764 and 9.343) for sole and Pb (0.210 and 0.213), Cd (0.264 and 0.307), Cu (0.442 and 0.483), Cr (0.577 and 0.597) and Zn (4.783 and 5.924) for croaker in the wet season (July-October). Significant (P~B 0.05) variations were observed in metal content between fish in terms of species, location and season. Generally, sole had higher metal concentrations than croaker; and metal contents were higher in samples from Lagos compared to Delta, probably due to the contribution of more effluents from industrial, commercial and municipal wastes in Lagos state. Cd and Cr levels in the test species were found to exceed international standards. It is recommended that a programme of continuous monitoring and control of the physical and chemical characteristics of components and food products of Nigeria's coastal zone be incorporated as a management tool for this important ecological zone.

    Description: A gross alpha and beta survey of the water of Kainji Lake was conducted using multi-channel analyzer, a proportional counter detector. This was done to estimate the gross radioactivity concentrations due to natural radionuclides in the lake water. Radioactivity, a phenomenon that leads to production of radiations, and radiation is known to trigger or induce cancer. The gross alpha and beta activity concentration analyzed in the water shows that the alpha activity ranges from 1.0 x 105 Bq/cm3 to 0.7Bq/cm3 with an average value indication of 0.0702Bq/cm3, whereas the beta activity concentration indicated BDL for all the sites with exception of upstream 01 location (9~' 51' 485' and 4~'35' 473'E) which has 0.0022Bq/cm3. This could be attributed to the continued flow of the lake water. Although radioactivity measured in lakes is usual higher than that of flowing waters, because a significant part of the radioactive substance brought in by other tributary rivers accumulates in it (Szaho et al.1998). That of Kainji Lake is entirely different.

    Description: This study was carried out to investigate the ability of Water Hyacinth (Eichhornia crassipes [Mart.]Solms) to absorb and translocate iron (Fe) and copper (Cu). The study was conducted with three concentration gradients of Fe and Cu at 10mg/l, 15mg/l, 20mg/l and control (no metal); the whole set-up was done in triplicates and the experiment lasted for 12 weeks. The results showed that iron (Fr) had the highest accumulation value in the root (1.12 ~c 0.42), while copper (Cu) had the highest value in the leave (0.38 ~c 0.06); both at 20mg/l. Statistical analysis showed that there was significant difference among treatment (p&lt0.05). Translocation factor (TF) is the ratio between metal concentrations in aerial part to metal concentration in the root. Metals that are accumulated by plants and largely stort in the roots are indicated by TF values less than 1, when greater than 1, its indicate good translocation capabilities. The TF value for Fe ranged from 0.49 ~c 0.57- 0.68 ~c 0.27 in leaf, and 0.64 ~c 0.17- 0.77 ~c 0.18 in the stem. While the Translocation factor values for Ca ranged from 0.78 ~c 0.08- 1.12 ~c 0.12 in leaf and 0.72 ~c 0.32- 1.09 ~c 0.19 in the stem. This reveals that Cu had better translocation capability than Fe. Highest values of bioconcentration factor (BCF) for Fe and Cu were 2.32 ~c 0.65 at 20mg/l and 0.72 ~c 0.01 at 15mg/l obtained in the root and leaf respectively, indicating that the accumulation potential of Fe by water hyacinth is higher than Cu. In conclusion, according to the accumulation capabilities of the investigated plant (Eichhornia crassipes), this study showed that the plant was found to be a promising candidate for phytoremediation and adequate for bio-monitoring programs for contaminated water.

    Description: This paper examined possible mitigation and adaptation measures in small-scale fisheries, aquaculture and the fishing communities in Nigeria to cope with the impact of climate change. It is recognized that mitigation measures in fisheries are limited but must consider options on the inputs, equipments and methods employed in fishing and fish processing activities. Several opportunities for options in the country's artisanal fisheries and aquaculture, and by the fishing communities to reduce their vulnerability change impacts, and protect the livelihoods and food security have been identified. The areas of research on climate change to enhance knowledge on the socioeconomic , biolog1cal and ecological impacts, and to guide decision on mitigation and adaptation in fisheries and aquaculture and the fishing communities, are also outlined. Proper integration of fisheries and aquaculture into the national policy on climate change and the political will for implementation are key to effective climate change mitigation and to ensure sustainable fisheries, and protect the livelihoods and food security in the country.

    Description: Plankton communities of Ikpa River, downstream from a sand-dredging area were studied for a period of i2 months (March 2010 to Febntary 2011), covering dry and wet seasons. Most Physico-chemical parameters (pH, Turbidity, Silicates, Transparency and Conductivity) exhibited highly significant spatial variation (p〈0.01), whereas seasonal variation of these variables was not statistically significant(p〉0.05). Significant seasonal variation (p〈0.05) was however observed in temperature, Dissolved Oxygen, Biochemical Dem and(BOD), total Dissolved Solids (TDS), Phosphorus, Nitrates and Conductivity. A total of 51 Taxa of Phytoplankton to 43 genera and 5 families were identified during the period of study. Bacillariophyceae recorded the highest relative abundance with 52.41%, followed by Chlorophyceae with 32.05%, Cyanobacteria with 13.35%, while Euglenophyceae and Dinophyceae 1.26% and 0.83%, respectively. Among the Diatoms,Melosira granulata was the most dominant species with Shanon Weiner's Diversity index (H1) of 0.23 and Simpson's Dominance Index (D) of 0.017. A highly significant variation (p〈0.01) was observed in spatial distribution and seasonal distribution of most of the algaegroups, whereas taxa occurence showed no significant difference (p〉0.05) among the stations and the seasons. A total of 8 taxa zooplankton belonging to 4 genera were identified. Rotifera were the most prevelent groiup with 4 taxa, followed by Cladocera with 2 taxa, while Protozoa and Copepoda recorded 1 species each. A highly significant spatial and seasonal variation (p〈0.01) was observed in Zooplankton abundance among the stations. The Zooplankton dominance profile also showed Rotifers ranking the highest with Shanon-Weiner's Diversity index (H1) of 0.21 and Simpson's Dominance index (D) of 0.014. Correlation coefficient also showed a highly significant relationship (r=0.881); p〈0.01) between Zooplankton and Phytoplankton abundance. Also, a highly significant relationship (r=0.961; p〈0.05) existed between overall plankton distribution and abundance and water quality parameters. Alternative sources of building materials such as Fly, Ash and Industrial Hemp have been recommended inorder to reduce or eliminate the need for building purposes.

    Description: A number of wells penetrating the Floridan aquifer in easternClay County were found to be losing water to permeable zones abovethis aquifer. A differential in artesian pressure was observed in closelyspaced wells of similar depth. Further investigation. revealed thatthe pressure differential in the wells was due to the design of thewells, of which there were four principal types.A comparison of the four types of wells in relation to the subsurfacegeology showed that three types of wells were open to the permeablezones above the Floridan aquifer. In such wells water of relativelyhigh head from the Floridan aquifer moves up through the well boreand out into zones of relatively low head.The estimated water loss from poorly designed wells rangedfrom 32 to 180 gpm (gallons per minute). The artesian head loss inleaky wells ranged from 3 to 15 feet. A total loss of water of 39 mgd(million gallons per day) was estimated from all the leaky wells inthe area. A significant decline of the piezometric surface of the Floridanaquifer was observed in eastern Clay County. Some of this decline canbe attributed to the loss of water from the Floridan aquifer throughthese poorly designed wells. (Document has 16 pages.)

    Description: The value of the natural resources of the White River Basin (Basin), AR isrecognized by the area's designation as a "Wetland of International Importance". TheBasin constitutes one of the Nation's largest remaining intact forested wetlandlandscapes, second only to the Atchafalya Basin. It supports the North Americancontinent's largest concentration of over-wintering mallard ducks, a world-class troutfishery, the last vestige of a big river fishery remaining in the Mississippi River Basin,and numerous threatened and endangered species. The continued viability of thiswetland ecosystem depends on the suitability of the hydrologic environment to theresident flora and fauna. Numerous modifications of the Basin hydrologic features in thepast century have seriously impaired the sustainability of these resources. The Basinwidealterations of hydrologic processes (e.g., impoundment and regulatory releases offlows and volumes in the upper reaches, navigational modifications of lower reaches, andconsumptive demands for agricultural use throughout) have affected the hydrology of thesystem profoundly. The result is highly regulated flows and stages, vastly alteredhydrologic patterns, over-stabilized water levels, and disruption of seasonal waterdistribution patterns. Given the critical nature of hydrology in regulating the structureand function of wetland ecosystems, the impacts have been devastating, particularly tothe critical bottomland hardwoods that support the Basin's fish and wildlife resources.To date these piece-meal, system-wide, hydrologic alterations have cornmutativelydegraded the habitat value of this resource for fish and wildlife in the Basin, and havelead to changes in their numbers and distributions. In spite of the enormous stakesinvolved, there has been no comprehensive characterization of the Basin hydrology.System alterations such as channel deepening, dam construction, water allocationplans, and flood control measures are currently pending. These projects will potentiallyhrther modify the hydrologic environments of the Basin, and no doubt require mitigationmeasures. In addition, there is genuine interest in restoring aspects of the Basin's historichydrologic regime within some set of reasonable limits. In order to proceed with thiseffort, the anticipated effects of these modifications and restorations on the Basin ecologyrequire thorough study of the area's historic hydrology, so that connectivity among Basinprecipitation patterns, flow fluctuations, and land use changes can be made. A basinhydrologic characterization is an initial component of this effort. The focus of this effortwas to determine and assemble the data set from which characterization of the hydrologicenvironments of the Basin using historic and recent water level, flow, (primarily byUSGS-WRD) at locations throughout the Basin could proceed.

    Description: Loxahatchee can be grouped into three zones according to the patterns of change of treeislands observed from 1950 to 1991. 1 ) the edge ofthe refuge adjacent to the canals, 2) the eastern interiorof the refuge, and 3) the western interior ofthe refuge. The general trend is for tree islandsAlong the edge of the refuge to have decreased insize, number, and percent cover, while those on theinterior increased in size, nunber, and percentcover.Results from this study illustrate the importanceof flow magnitude as well as hydroperiodand depth in stucturing patterns of tree islandswithin this peat wetland. Restoration of historichydroperiods and depths without historic flow patternsmay not be sufficient to restore or maintainthe historic pattern and function of the system. (60 pages)

    Description: We present a new modeling method for use in large-scale physical systems, such as the Everglades ecosystem.The current work that has been done in the ATLSS (Across-Trophic-Level System Simulation) project-whichfocuses on simulating key Everglades system components-relies on code integration. While this represents anecessary first step in analyzing the dynamics of species within the Everglades, it falls short of true modelintegration. We have constructed a methodology called object-oriented physical modeling (OOPM), which allowsa comprehensive knowledge representation to be constructedfor large-scale systems. OOPM enforces theidea that an implementation ofcomputer code can be accomplished in an incremental fashion by starting with aconceptual model and progressing to more detailed models. During this evolutionary procedure, a minimal amountof code is written, since the emphasis is on developing the conceptual model so that it not only represents theintuitive aspects ofthe model, but is also executable. OOPM provides a kind of "blueprint" for ecologists, biologistsand hydrologists to communicate and integrate models effectively. (14 page document)

    Description: The water problems confronting Hallandale are similar to those of othercoastal cities of southeastern Florida which are undergoing rapid growthwith tremendous increase in water demand. The highly permeable Biscayneaquifer underlying the Hallandale area is an excellent source ofwater; however, the permeable nature of the Biscayne aquifer would permitthe intrusion of sea water, if fresh water levels were lowered excessively,as well as the infiltration of urban or industrial contaminants, fromland surfaces and surface water bodies.This study is to provide the hydrologic data necessary for proper waterresource development and planning in the Hallandale area.(40 page document)
