    Description: The growth performance and nutrient utilization in Clarias gariepinus fingerlings fed cooked breadfruit (Artocarpus altilis) seed meal based diet as a replacement for maize, investigated for 8 weeks. Five (5) diets of breadfruit seed meal substituted for maize at different levels of inclusion (0%; 25%; 50%; 75% and 100%) were fed to the fingerlings at 5% body weight twice daily in hapa of 1m x 1m x 1m. The hapas wee submerged in a pond and each hapa stocked with 20 fingerlings of mean weight of 5.8~c0.00g. Evaluation of growth parameters nutrient utilization of the experimental diets showed that there was no significant difference (P〉0.05) in mean final weight (MFW); specific growth rate (SGR); feed conversion rate (FCR) protein efficiency ratio (PER) and apparent net protein utilization (ANPU) among the treatments. The results suggested a net advantage of replacing dietary maize with cooked breadfruit seed meal for Clarias gariepinus fingerlings at 50% and above levels of inclusion under the condition of the experiment.

    Description: The physical and chemical characteristics of freshwater bodies Ikot Ebak and Abeneyentem streams in Essien Udim Local Government Area, Akwa Ibom State, Nigeria were studied from (July December 1996). The mean values obtained in the two water bodies were pH (6.8~c0.12, 6.8~c0.09, respectively). Conductivity (4.9~c2.26, 5.0~c2.09 iScm-1), total dissolved solid (16~c7.58, 37~c26.9 mg/l), TSS (46~c26.0, 53~c53.1)g/l), alkalinity (17.5~c7.27, 10.7~c8S MgCaCo3/1), DO (6.98~C1.46, 8.3~C29.0mg/1), BOD (2.65~c2.44, 3.15~c2.79mg/1), Salinity (0.41~c0.12, 0.31~c0.04%o') total hardness (0.64~c0.21, 0.84~c0.42mg/l, N03-N (0.31~cO.26, 0.35~c0.29mg/l), and PD4-P (0.022~c0.0199 0.023~c.022mg/1), respectively. There were significant difference in the means of the parameters in the two water bodies except TDS, Alkalinity and Hardness. The water bodies were found to be slightly acidic with low conductivity. The properties in the water bodies were in conformity with international standards for both drinking and aquatic life.

    Description: 200 fingerlings of African catfish (Clarias gariepinus) of average weight of 22.8~c0.04g were used to investigate the nutritive value of Pawpaw (Carica papaya) leaf-based diets. Five (5) isocaloric and iso-nitrogenous diets containing fishmeal protein at a rate of 0%, 25%, 50%, 75%, and 100% along with the pawpaw leaf were formulated. The diet without the pawpaw leaf meal serves as the control. The fish fingerlings were fed at 5% body weight per day for 56 days in plastic bowls. It was observed at the end of the experiment that pawpaw leaf meal was suitable as a protein supplement when incorporated at 50% replacement. The body weight gain, specific growth rate (SGR) and food conversion ratio (FCR) values of 18.68g, 1.07%/ day and 4.72 respectively were highest in diet with 50% replacement closely followed by diet with 25% replacement. Based on the results, it could be recommended that in practice 50% replacement of pawpaw leaf meal with fish meal is optimal in practical diet of African catfish (Clarias gariepinus) fingerlings. Nevertheless, complete replacement of pawpaw leaf meal decreases growth rate and should not be used in Clarias gariepinus fingerlings.

    Description: The objective of this study was to determine the best smoking method that will enhance consumer preference for Clarias gariepinus without affecting negatively the nutritive value. Two methods of smoking were used: cold and hot smoking. The fish were smoked with improvised drum smoking kiln and oven. Smoked fish samples obtained were subjected to chemical analyses and sensory evaluation. Chemical analyses showed that the smoked fish were still rich in protein (66.0067.52%) and fat (9.83-12.28%); while the moisture content ranged between 7.82-8.24% and ash, 12.86-14.16%. There was no significant difference (P〉0.05) in the protein, ash and moisture contents. Significant differences (P〈0.05) were observed in the Calcium(Ca), Potassium(K), Sodium(Na), Zinc(Zn), Lead(Pb), Iron(Fe) and Phosphorus(P) contents. Only hot smoke-dried (HSD) fish samples showed no presence of lead. The levels of sodium(Na) and potassium(K) in the smoked fish were relatively high, though, the amount of potassium(k) was higher. Sensory evaluation results revealed that there were no significant differences (P〉0.05) in the colour and taste ratings of the smoked fish samples. However, significant differences (P〈0.05) were observed in the odour, texture and overall acceptability. Hot smoke-dried and cold oven-dried Clarias gariepinus had the best overall acceptability in ratings.

    Description: Lagos state has a major sea port for landing of frozen fish from Mauritania, Senegal, the Scottish waters and other European countries. In the last three years, the dense population of the state has encouraged all kinds of trade to thrive. Fish as a major food in many Nigerian diets has been known to complement the high carbohydrate intake of majority of the Nigerian populace because of the unaffordable prices of beef in the market. The market for frozen fish is rich in Lagos. It has provided many women fishmongers a livelihood for over a decade. They have been able to sustain their families and improve their social status over the years. This study reports the modus operandi of the trade. The study covered a period of three months. Fish sales were monitored in Epe, Oyingbo, Ijora and Alaba markets. The cooperation of the heads of markets (Iya Olojas) were requested at every market. It was ensured that observations and the interviews/questionnaires do not interfere with the women's activities. Specific areas focused upon in the study included countries of fish imports, most acceptable species, packaging, purchase price, sales price and profit margins. Other important factors in the fish market that were studied included entrance into the fish marketing business, sources of finance and problems. The study also made suggestions on how to improve upon the fish marketing business of women in Lagos State.

    Description: An experimental growth trial in floating net-hapas at three stocking densities in concrete pond was carried out. 4.68 5.25g mean individual weight fish were stocked at 25, 50 and 100 per m3. A 40% protein balanced diet was used as feed. The results of the study showed no statistical significant difference in growth among the three treatments. Food conversion ratios ranged in 1.60 to 1.82, and specific growth rates were between 3.80 and 4.16%/day. The result suggests that culture of C. gariepinus at a density of 50/m3 and production of 4.15kg/m3 in 84 days with production of 8.30kg/m3 in a growing season of 180 days is possible using the net-hapa systems enclosed in a concrete pond.

    Description: In recent times there has been an upsurge in the culture of Tilapia in Nigeria resulting in increased demand for the fingerlings which is hardly satisfied. This is due to increasing demand for table size tilapia as food fish and under-sized tilapia in the fish meal and fish canning industries in Nigeria. Collection of Tilapia guineensis fingerlings from the wild, to augment hatchery production, has been the practice and this is subject to environmental fluctuations. Multivariate regression and correlation analyses of accumulated data were used to investigate the effects of changes in water quality parameters on abundance of fingerlings of Tilapia guineensis in a brackishwater habitat in Lagos. Dissolved oxygen (DO), salinity and secchi transparency were found to be the most dominant factors affecting the abundance of Tilapia guineensis fingerlings in the Lagos lagoon. Peak period of abundance was closely associated with period of low salinity (0.50%o to 5.60%o), which coincided with the period of low transparency and low DO in the rainy season. The correlation analyses of Tilapia guineensis fingerlings with the water quality parameters yielded the following correlation coefficients (r)- 0.598; (salinity); -0.644 (transparency); -0.710 (DO); -0.566; (temperature) and 0.129 (pH). The abundance of Tilapia guineensis fingerlings in the Lagoon was ultimately defined by a suitable regression equation. This result is expected to optimize the collection of fingerlings of Tilapia guineensis from the wild and boost food fish security in Nigeria and elsewhere.

    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: Study was conducted to investigate lipid profile and metabolites in deformed (lost one or both pectoral fins) and healthy (both pectoral fins intact) African mud catfish C. gariepinus using three groups of adults male and female with a mean weight and standard length of 822.17~c 48.75g and 42.55~c.26cm respectively. The fish were allotted in replicates to 5000m capacity tanks based on the presence or absence of pectoral fins. 1mL blood was drawn from caudal peduncle of each fish by means of disposable sterile syringe and centrifuged at 1000rpm for 20min at 40C. Cholesterol and total protein were determined using the cholesterol FL (CT F400CH) and total protein (TP 0500CH) kits. Serum albumin and globulin concentrations were determined following methods described by Tietz (1995) and Buckley et al., (1976) while total serum bilirubin concentration was measured as outlined by AACC (American Association of Clinical Chemistry). Results indicate that male fish had relatively higher amount of triglyceride while female fish had higher amounts of cholesterol, reduction in globulin of the deformed fish, reduction in the concentrations of albumin in healthy fish, increase in total protein and globulin levels and high urea concentrations. No total bilurubin was detected in any of the fish sampled thus an indication of good liver function which means there was no liver dysfunction or liver damage in the fishes. It is evident therefore that abnormal fish can still perform better if they are given intense management because of the variability in their blood constituents with the normal fishes which is used to assess their health is minimal.

    Description: A study was conducted in Abeokuta, the Ogun State capital with the objective to investigate if fish trading could be a tool of poverty alleviation and socio-economic enhancement of the status of women in the household. A total of 120 correctly completed, structured and pre-tested questionnaires, out of the 150 administered to respondents, were retrieved for data analyses. Demographic data of the traders showed that all the respondents were women whose ages ranged from 15 to above 45 years. The ages of 33-45 years constituted 33.3% of the respondents while the age bracket of between 27-32 years constituted 23.3%. Majority (73.3%) were married while 25% were single-headed households (divorced or widowed). The study revealed that most of the respondents (approximately 61%) were able to meet their family expenditure jointly with their spouses while 28.3% of the respondents met the financial responsibilities of their families solely from the profit. Access to credit was found to be a major limitation. The study further revealed that 86.7% of the respondents would like to continue with the business because they were satisfied with the profit accruable to them from the trade.

    Description: This paper begins with a review of policy issues on status of women’s fundamental human rights and the effects on their optimal participation in fisheries development. The focus of the paper is on the importance of women in fisheries activities within the fisheries industry. Issues pertaining to gender inequality in the rural communities affecting women in the fisheries sector, and solutions to overcome some of these issues are discussed. The degree of participation of women in the fisheries sector is an overall reflection of the cultures, the laws of the country and the priority given by the state to ensure gender equity. Generally, women in Nigeria, especially those from depressed fisheries households, participate actively in many fisheries activities, including aquaculture. However, the lower status accorded to women in many of the communities in Nigeria means that their contribution to fisheries is undervalued and unrecognized. Issues that need to be addressed with regards to participation of women in fisheries which include sensitivity to gender issues in fishery, improve living conditions, promote programs relating to women, reconsidering the practice of relating fishing rights to their right to speak and others are discussed in the paper The paper also looks at the possibilities of articulating measures in sensitizing the womenfolks through education, especially in knowing their fundamental human rights as specified by the UN’s articles, especially ability to access micro-credit in fisheries activities, the nature of loans and alternative strategies to tackle the problem of small-scale credit to women in fisheries development in the nation.

    Description: Ifiayong is a small local village market where economically and commercially important fin and shellfishes are landed. It is located very close to the Five Star and Ibom Le Meridian Hotels at Nwaniba beach. Women functioned as transporters, sorters, processors, financiers, distributors and marketers of the thirty-two finfish families, seven shellfish species together with three turtles (reptiles) encountered at the study site. Socio-economic survey revealed that ninety-four women modally aged 46-55years (34; 36.17%) participated in the fisheries and frequently communicated in Efik (40; 42.55%), and were mostly drop-outs (40; 40.56%) in educational level and polygamous (35; 38.30%). The modal family size was 11-15 persons (45; 47.87%) who invested N 41,000 - N 50,000 (28; 29.79%). Problems encountered by these women together with the corresponding solutions and appropriate recommendations proffered were highlighted with the aim of making Ifiayong a revenue generating and tourism centre for Uruan Local Council and Akwa Ibom State Government.

    Description: The effect of substituting soybean meal with raw sunflower and sesame seed meal was evaluated using haematological indices of Clarias gariepinus fed the diets containing sunflower and sesame seed meal. Seven isonitrogeneous and isocaloric diets containing sunflower and sesame seed meal replacing soybean meal at a rate of 15, 30 and 45% were prepared. A diet without replacement of soybean meal served as control. The result of fish fed test diets showed significant (P〈0.05) difference over the fish fed control diet with respect to PCV and mean corpuscular volume (MCV). Fish fed control diet had the lowest Hb, PCV, WBC, RBC, MCV, MCHC, ESr. There was no significant difference (P〉0.05) in the fish fed control diet and test diets with respect to MCH, MCHC, ESr, Neutrophil, Monocytes, Eusinophils and Lymphocytes. Hence it can be concluded that the haemotological parameter of Clarias gariepinus is not significantly (P〉0.05) changed with increase dietary inclusion of raw sunflower and sesame seed meal.

    Description: Feeding trial was conducted in static water to assess the growth of Clarias gariepinus fingerlings fed different inclusion levels of Mucuna seed meal (MSM). Raw MSM was used at 10%, 20% and 30% inclusion levels and the performance of fish fed these diets was compared with the fish fed soybean-based diet which contained 40%protein. All diets were prepared to be isonitrogenous and isocaloric. A four by six factorial experiment with three replicates using ten fish each of average initial weight of 6.6g was carried out. Daily fish ration of five percent body weight was administered two times for twelve weeks. The specific growth rate (SGR) in diet 1 (control) was significantly (p〈0.05) higher than the other dietary groups and worsens as inclusion level increased similar trend was also observed in the food conversion ratio (FCR) and protein efficiency ratio (PER). The significantly lower growth performance of fish fed diets containing raw MSM might be due to the presence of anti-nutritional factors present raw MSM. The possibility of improving this trend through processing should be investigated.

    Description: Clarias gariepinus juveniles 6.35 ~C 0.22 g weight were fed five different commercial diets for 105 days to determine growth rates. Diets were hand distributed in triplicate groups of 30 fish once daily. The diets used were Coppens, Multifeed, Eurogold, Vittal and Ajanla feeds. At the end of the experiment, the final mean weight for Coppens, Multifeed and Eurogold were 181.54 ~c 0.63 g, 179.92 ~c 0.95 g and 139.92 ~c 0.26 g respectively, while final mean weight for Vital and Ajanla were 110.11 ~c 0.23 g and 119.03 ~c 0.35 g respectively. The statistical analysis of the results showed that there were significant differences (P〈0.05) in the mean final weights. Also there was no significant difference (P〉0.05) in the mean final weight between Coppens and Multifeed. The specific growth rates (SGR) were 3.19% day-1 3.18 % day-1 and 2.94% day-1 for Coppens Multifeed and Eurogold respectively and 2.71% day-1 and 2.78% day-1 respectively for Ajanla and Vital. There were significant differences (P〈0.05) in SGR among treatments and no significant difference (P〉0.05) between SGR of Coppens and Multifeed. Based on these findings, it was concluded that feed with macronutrient combinations of 45% CP, 12% crude fat, crude fiber, 1.5%, Ash 9.5% promoted better growth rates in C. gariepinus juveniles as compared with other combinations.

    Description: Clarias gariepinus (0.73 ~c 0.01g) and Heterobranchus longifilis fingerlings (0.67 ~c 0.01g) were fed five isonitrogenous diets of about 40% crude protein, with varying levels (0-100%) of palm grub meal for 12 weeks. At the end of the study, C. gariepinus and H. longifilis fingerlings fed 25% palm grub inclusion diet had the highest weight gain (5.30g and 4.05g respectively), relative (726.0% and 595.6%) and specific (1.09% and 1.00%) growth rates while those fed 100% palm grub inclusion diet showed least growth; weight gain (2.68g and 2.15g), relative (367.1% and 316.2%) and specific (0.80% and 0.45%) growth rates respectively. Food conversion and protein efficiency were also best in fingerlings fed 25% palm grub meal diet (0.70 and 1.35 for C. gariepinus; 0.75 and 1.35 for H. longifilis respectively) with decreasing efficiency as palm grub inclusion level increased in the diets. The differences in the growth and nutrient utilization of the fingerlings on the various diets were generally insignificant (p〉0.05) above 25% inclusion level of palm grub. The study showed that palm grub can be used to completely replace fish meal in mudcatfish diets. However, for optimal growth and nutrient utilization, 25% level of replacement of fish meal with palm grub meal is most adequate in C. gariepinus and H. longifilis fingerlings diets.

    Description: The paper examined gender and fisheries of Lake Kainji, Nigeria. The study highlights socio economic characteristics of women involved in Kainji Lake fisheries, important issues about gender and fisheries. It reveals that the categories of women in the Kainji Lake fisheries are in the middle age of 31 to 40 years with very low educational background. It also indicates that fish processing has been the most prominent activity of women in fisheries of Lake Kainji and constitute about 60 percent of the women. The study concludes that women play significant roles in all aspects of fisheries in Lake Kainji. Importantly, women’s roles span reproduction and production.

    Description: The physico-chemical and biological characteristics and nutrient concentration of Kigera Fish Farm ponds were monitored for two months to assess the water quality. The parameters measured were dissolved oxygen, temperature, hydrogen ion concentration, Secchi-disc transparency and zooplankton composition. Some fish species were identified in the course of study. Temperature ranged from 26 -30degreesC; dissolved oxygen ranged from 3mg/l-6.6mg/l, pH ranged 7.0 -7.2; while Secchi-disc transparency ranged from 0.19 - 0.25m. The three ponds were quite similar in these parameters. All the parameters that were investigated in this study are within the tolerable level for warm water fishes. Five different zooplankton species were identified at the Kigera Fish Farm, and were grouped according to their major categories namely: Copepods, Cyclopoids and Copepodite), Cladoceran (〈i〉Moina〈/i〉), and Rotifera (〈i〉Asplanchina〈/i〉). 〈i〉Branchionus〈/i〉 species in the Rotifers group dominated the zooplankton species in all the three ponds.

    Description: Intraspecific hybridization studies were carried out in three strains of Clarias gariepinus obtained from three ecological zones in Nigeria: rainforest; (Onitsha strain), Guinea savanna, Kainji strain) and Montanne vegetation, (Jos strain) with the aim of improving the growth performance of the species. Nine genetic mating combinations were generated from the three strains and were successfully induced under controlled hatchery conditions. Indoor and outdoor growth parameters were monitored. The 19 days growth indoors showed significant difference (P〈O.05) in weight gain. Highest weight gain (2.76g) was obtained in Jos parental strain and cross involving female Jos and male Kainji, while the least was recorded in female Kainji and male Onitsha (0.062g). The 50 days outdoor growth performance also showed significant difference between the genetic mating combinations. Maximum weight gain (464.57g) was observed in female Kainji and male Onitsha, while female Jos and male Kainji gave 263.94g weight gain. There was no significant difference (P〉0.05) in length in both indoor and outdoor rearing. Based on this study, the cross-involving female Kainji and male Onitsha is recommended for fingerling production of Clarias gariepinus.

    Description: Salted and saltless Clarias gariepinus were smoked and oven dried. Their proximate composition and sensory qualities were assessed using standard methods. The salted oven dried fish has mean values of 65.00% (crude protein); 21.90% (fat); 6.40% (moisture); and 0.79% crude fibre while the saltless had lower mean values of 64.50% (protein); 20.95% (fat);5.68% (moisture) and0.40% crude fibre. The ash content of the saltless oven dried fish 7.34% was higher than the salted 6.46%. The salted smoke dried fish has 64.07% crude protein; 20.74% (fat), 6.51 % moisture; 8.54% ash and 0.53% crude fibre. Thus, the oven dried samples have higher protein and fat values than the smoke dried samples. The salted samples have higher values of these nutrients than the saltless ones. Salting perhaps increases the availability of nutrients in smoked and oven dried Clarias gariepinus. Sensorily, there was no significant difference (P〉O.05) in taste, texture and overall acceptability of salted and unsalted smoked and oven dried Clarias gariepinus. A significant difference existed in their colour and Flavour. The colour of the saltless smoked dried fish was most acceptable. While the flavour of the 5% salted smoked dried fish was preferred. The salted oven dried fish had the highest overall acceptability score

    Description: The seasonal variations in the physicochemical parameters were studied from January, 2007 to December 2007, in Kontagora Reservoir, Niger State, Nigeria. The physico- chemical parameters were determined bi-monthly , using the following methods , temperature using mercury thermometer in degree centigrade, transparency using Secchi-disc , Pye Unicam model 292 meter used for pH and electrical conductivity. Dissolved oxygen by modified Winklerazide method, water hardness and Phosphate- phosphorus by method of Lind (1979), total alkalinity by standard method described by Boyd(l979) , Nitrate- Nitrogen by Phenoldisulphonic acid method. The rainy season mean values for water temperature, depth, pH, Nitrate-Nitrogen, were significantly (P〈0.05) higher than those for the dry season. However, for transparency, conductivity, dissolved oxygen, hardness, alkalinity, phosphate-phosphorus and total dissolved solid, the dry season mean values were higher than the rainy season mean value. As in most other Africa inland water bodies, there was seasonality in the physicochemical parameters variables. The torrential rains of the dam environment, the characteristics trade winds of the dry season, effect of deforestation, fertilizer application, herbicides, insecticide and other chemical factors might have contributed to the fluctuations of some of the physicochemical parameters detennined in the Reservoir.

    Description: The objective of this study was to compare the nutritive value of boiled Colocasia esculenta flour (CECF) with that of yellow maize in practical rations of fingerlings. Boiling resulted in a slight increase in crude protein content and significant (84.5%) decrease in oxalate content. Five is oproteic (30% crude protein) and isocaloric (15.46 Kjg-1) diets were formulated. The control diet contained maize as the principal dietary energy source, while flour produced from boiled Colocasia corn progressively replaced maize at 5 inclusion levels (0%, 20%, 40% 60% and 80%). The experimental diets were fed to triplicate group of Clarias gariepinus fingerlings (mean weight 2.05~c0.5g) at 3% body weight day-1. Growth performance expressed as weight gain, specific grown rate (SGR) and nutrient utilization expressed as feed conversation ration (FCR), protein efficiency ration (PER) were assessed. There was a trend of decrease in weight gain with increase in inclusion level of CECF. Weight gains of groups of C. gariepinus fed up to 60% inclusion level of CECF were nog significantly (p〉0.05) different from the group fed the control diet, the same trend was observed for SGR. FCR and other parameters were poorer (p〈0.05) in digestibility coefficients among the different groups, also that carcass composition did not vary significantly (p〈0.5) among treatments. Results also indicate that CECF is an acceptable ingredient that can replace maize up to 20% inclusion in C. gariepinus rations.

    Description: Interspecific and intergeneric hybridization studies were carried out in H. longifilis, C. gariepinus and C. anguillaris under controlled hatchery conditions to estimate their aquaculture potential in terms of fertilizability, hatchability and survival. Fertilization rate in all the nine genetic crosses ranges from 60-87.5%, the fertilization rates of the parentals being significantly higher(P〈0.05) with highest value of 87.5% obtained in C. gariepinus. The intergeneric hybrids had the lowest rate of fertilization. Hatchability ranges between 75- 88.1 %, with the parental C. anguillaris being slightly significantly higher than the other genetic combinations. C. anguillaris x H. longifilis I had the lowest hatchability and there was no significant difference (P〈0.05) in percent hatching among the the interspecific hybrids. The survival of all the nine genetic crosses from hatching up to the end of the two weeks indoor rearing period ranges between 78-89%, which wasn't significantly different among the interspecific and intergeneric hybrids. C. anguillaris and C. gariepinus had the highest percent survival which was significantly different from all the other mating combinations. The intergeneric hybrid larval had significantly greater (P〈0.05) length in comparison to the interspecific hybrids. H. longifilis and the hybrids produced from its eggs had greater body weight than that of C. gariepinus and C. anguillaris

    Description: Study on the growth and percentage survival of seasonal induced breeding was carried out at the Federal College of Freshwater Fisheries Technology Baga. About 40,414 fingerlings were produced with percentage survival of 81.1 % at water temperature of 28degrees C between April and May, 2009. The average weight of fingerlings produced was 1.54 g with average standard and total length of 3.0 cm and 3.5 cm respectively. However, environmental factors that could hinder mass production of Dutch Clarias fry/fingerlings stocked at low and high stocking densities were monitored for eight weeks at 3.6 m2 indoor concrete tanks with water aeration using flow-through system. The percentage survival of 83.5% and 92.5% were obtained after the period of 8 weeks. The fry/fingerlings were fed with Artemia mixed with powdered feed of 35 % crude protein. The study shows that for Dutch Clarias fry/fingerlings production and management, smaller concrete tanks with flow-through mechanism are required and 3.6 m2 should not be stocked with more than 3,500 fingerlings per tank in the first 8 weeks before transferring them to production ponds. It was observed that apart from efficient water aeration, constant feeding and sampling of fingerlings will increase growth rate, increase resistance to disease and uniformity in size of the Dutch Clarias. The mean water temperature measured in this study ranged from 27.5degrees C in April and 28.5degrees C in May while pH ranged between 7.5 and 7.3 in April and May, respectively.

    Description: Preliminary studies on the antimicrobial properties of various methods of extraction of Carica papaya (Pawpaw) seeds, Citrus paradisa (Grapefruit peel) and Piper guineese (Black pepper) seeds against eleven bacteria ( Proteus mirabilis, Escherichia coli, Staphylococcus aureus, Acinetobacter sp, Klebsiella pneumoniae, K. oxytoca, Pseudomonas lundensis, Bacillus subtilis, B. megaterium, Citrobacter freundii and Enterobacter cloacae) associated with fresh catfish spoilage were investigated using the cup-plate diffusion method. Cold water, hot water and ethanol were the different extraction solvents used while the concentrations were 0.1g/ml, 0.2g/ml, 0.3g/ml, 0.4g/ml and 0.5g/ml. Generally, hot water extraction of the plant materials was most effective (p 〈 0.01) with the highest mean zone of inhibition of 4.42 ~c 0.38mm followed by ethanol extraction (3.55 ~c 0.47mm). The most susceptible bacteria was Enterobacter cloacae with the highest mean zone of inhibition of 22.6 ~c 3.50mm. This investigation indicates that the antimicrobial compounds in grape peel and black pepper are best liberated when extracted with ethanol while that of pawpaw is best extracted with hot water.

    Description: The morphometric characters of Cynothrissa mento from three major Lagoons (Ologe, Badagry and Epe) in Lagos, Nigeria were compared to assess the possibility of this fish species from the three Lagoons belonging to the same sub-population. The length-weight relationships (LWR), and condition factors (CF) of the fish were also described as well as the physico-chemical parameters of the three water bodies. The study was conducted between May, 2009 and April, 2010 and monthly sampling of fish and water was done in each sampling site. Seven7 physico-chemical parameters were assessed and these are; temperature, pH, salinity, turbidity, dissolved oxygen, total alkalinity and total hardness. A total of 294 specimens (Ologe 60, Badagry 174 and Epe 60) of C. mento were collected from the landings of the local fisher folks from the sampling sites. Seven morphometric characters; total length (TL), standard length (SL), body depth (BD), head length (HL), head depth (HD), eye diameter (ED) and interorbital width (IW) were measured. There was no significant difference (p 〉 0.05) in all the physico-chemical parameters measured among the sampling sites except pH. Coefficient of difference revealed that the C. mento from the three lagoons are uniform in all the morphometric parameters examined, which means that the specimens from the three sampling sites do not belong to different sub-populations. The growth coefficient/slope (b) values obtained for the fish species from the sampling sites ranged from 2.27 - 2.53, and differed significantly (p 〈 0.05) from 3, which indicates that most of the fish species have negative algometric growth.

    Description: An experiment was conducted to determine the survival rate, fertilization rate, growth performance and feed utilization of the reciprocal hybrids of Clarias gariepinus and Heterobranchus bidorsalis. Two genetic crosses were made: C. gariepinus (male) x H. bidorsalis (female)(Clariabranchus) and H. bidorsalis male x C. gariepinusmale (Heteroclarias. The experiment was divided into two phases; artificial propagation of the fish species using synthetic hormone and rearing the fry for 14 days; and rearing the 14 days old fry for 35 days. In the first phase of the experiment, survival of frys were estimated in each experimental unit (genetic cross) while in the second phase, growth and nutrient utilization were investigated. The result revealed that the highest %fertilization, hatching rate and %survival occurred in H. bidorsalisfemale x C. gariepinus male (Heteroclarias) and the differences were significant (p 〈 0.05). Percentage weight gain and specific growth rate were significantly (p 〈 0.05) higher in Clariabranchus than Heteroclarias. Based on the result of this study, reciprocal hybrids of Clarias gariepinus and Heterobranchus, bidorsalis is recommended for commercial aquacultural practices.

    Description: In many developing countries, active agricultural production takes place in the rural areas. The exploitation of natural fish stocks is reaching limits and aquaculture production has not yet fulfilled its potential despite the large expanse of land in our rural areas. Social and economic indicators for developing countries consistently show that women bear the brunt of hardship in poor communities. The World Bank aims to reduce gender disparities by enhancing women’s participation in economic development. The recent transformation in the country pursues microfinance as a poverty alleviation tool capable of improving the living standard of the rural dwellers to promote their productivity. Globally, women constitute the majority of microfinance clients because of their consistent in their repayment records. In Nigeria about 98% of microfinance institutions are located in the urban areas, which make accessibility difficult for rural dwellers. This paper reveals the need for microfinance institutions in improving fish production through aquaculture, thus enhancing women empowerment and livelihood. The pursuance of this goal will in effect, affect socio-economics of rural women and urban drift of young women in search for greener pasture.

    Description: Women are the majority of the third World population. They are considered subservient to their male counterpart, even in Europe and America where women have greater basic human right. This paper evaluates the various roles of women in Fisheries and fish processing. Statistics from the European Union shows that, of the various fishing sectors, participation of women (in terms of number) was greatest in fish processing, followed by marine aquaculture, marine fishing and inland aquaculture, with no women involved in inland fishing. In Asia and Africa women are basically involved in fish processing and marketing. In Asia (Thailand and Philippines), women are involved in hatchery operations in aquaculture in addition to fish processing. The finding of the review shows that Fish processing in developing countries, principally Africa is not attracting young literate generation who may have better management competence. It further revealed that, in Nigeria women are directly involved in capture fishery, in addition to fish marketing and processing. This is aimed at empowering women economically to meet the pressing needs of the family. The paper further assesses the problems of women in fisheries and fish processing namely, access to financial resources, education, support services and the need to ensure food security. Possible ways of improving women’s participation in fisheries were highlighted.

    Description: Survival of C. gariepinus hatchlings from different sizes of brood stocks and separation of the hatchlings from egg shells and unhatched eggs using incubating net hapas were examined under indoor hatchery condition in glass aquaria tanks using well water. The net hapas were constructed using net with mesh size 1 mm which with held normal size or fully grown fish egg but allowed hatchlings from the eggs to pass out of the hapa into the incubating tank. The hapa facilitated easy separation of hatchlings from egg shells and dead eggs, only small undeveloped eggs passes through the hapa because they were smaller than the mesh size. The use of incubating net hapa with kakabans inside did not have any effect on incubation period, hatching and survival of the hatchlings. The eggs hatched normally within 24 hours at temperature range of 26 27degreesC. About 98% hatching and separation of the hatchlings from egg shells was achieved. Survival of hatchlings was enhanced because pollution due to decaying eggshells and unhatched eggs was eliminated. The same experiment was used to test survival of hatchlings from broodstocks of varying sizes (500gm, 350gm and 250gm). The survival and mortality rate of hatchlings from the three different brood stock sizes were 77.3% mortality, 22.7% survival, 75.9% mortality, 24.1% survival and 68.1% mortality, 31.9% survival for 500gm ,350gm and 250gm broodstocks respectively. Statistically, there was no significant difference (P〉0.05) in survival and mortality rate of hatchlings from different sizes of broodstocks. Fecundity obtained from the brood stocks were 42,972; 50,925 and 80,878 for 250g, 350g and 500g broodstocks, respectively.

    Description: A 35-day feeding trial was conducted to compare and evaluate nine first feeds for Clarias gariepinus. The nine feedingstuff materials contained more than 40% crude protein. Artemia, coppens and fishmeal were used as single protein sources. Fish egg meal, cattle liver meal and shrimp meal were supplemented with yeast alone or yeast combined with folic acid. Twenty fish larvae were kept in plastic bowls with replicate for each treatment inside the laboratory. Feeding commenced after yolk absorption. Each diet was fed to fry twice daily to apparent satiation. Percentage survival at the end of the experimental period ranged between 0% and 100% for fish on fish egg supplemented with yeast and folic acid and liver meal with yeast respectively. Fish fed artemia had the highest weight while those on shrimp meal supplemented with yeast had the least. Highest specific growth rate was in fish fed fish egg supplemented with both folic acid and yeast. The cost of rearing Clarias gariepinus larvae can be appreciably reduced by using non conventional protein sources, which are locally available, for feed preparation.

    Description: The proximate composition of the fresh water shrimp Atya gabonensis (Irvine), preserved by smoking, salting and sun - drying was determined and compared to the fresh shrimp. All the preservation methods significantly (p〈 0.05) increased the total dry matter (38.34 93%), protein content (17.31 48.9) and ash content (28.36 36.17%) over the fresh shrimp value. Moisture and lipid contents however, were reduced from the fresh shrimp's 61.66% and 25.29% to low value of 7.00% and 5.10% respectively. The preserved shrimp is, therefore, nutritionally superior to the fresh shrimp as preservation enhances its proximate composition. Of all the preservation methods used in this work, smoking is the best. It recorded the best preservation indices of lowest moisture content, higher dry matter, higher protein content and highest ash content.

    Description: To determine the aeration regime and the resultant dissolved oxygen input that imposes the least physiological stress on homeostatic mechanisms of C. gariepinus fingerlings, were culture in the laboratory under 24 hours of continuous aeration and inputing a mean of 8.2 mg/l of 02; 12 hours of aeration (mean of 4.6mgO/l2); and zero-aeration (mean of 1.2 mgO/l2)' Survival rate, growth rate and mean weight gain per day were highest in the 4.6 mgO/l2 culture whereas, the other two cultures were characterized by higher mortality rates and insignificant growth rates. The haematological profile analyzed showed varying degrees of changes in the blood parameters of the fish cultured under varying levels of aeration and their inputed dissolved oxygen levels.

    Description: Women constitute the major stakeholders in the struggle for sustainable rural development in subSaharan Africa. The major fishing activities of women are in the area of processing, marketing and gear making. Women's fundamental contribution is continually under-appreciated and under-supported and is often adversely affected by prevailing economic policies and other developmental conditions.These circumstances must be reversed since sustainable development through fish production and marketing can not be achieved without the full participation of women. This paper is focused on how women can be empowered for sustainabledevelopment in fish development and marketing.

    Description: The involvement of women in aquaculture in Lagos State was studied. One hundred and fifty copies of the questionnaire were administered to women fish farmers, randomly selected from three local government areas of Lagos state. These were Ojo, Ibeju Lekki and Epe local government areas of Lagos State. The study revealed that 52% of the women adopted concrete pond system, 24% adopted dug-out or earthen pond system, 10% fibre glass tanks and 14% adopted Water Recirculatory/Flow-through system of fish farming. Other fish farming technologies that were included in this study were: stocking rates, feeding regimes and feed types, water quality management, general management of the farm, security, harvesting and marketing. These are the fish farming technologies that have been disseminated by the Nigerian Institute for Oceanography and Marine Research to women fish farmers. An average of 2 metric tonnes of fish per annum was calculated for each woman fish farmer in Lagos State. The bio-data of the women studied showed that fish farming can be practised by every woman, irrespective of age, educational standard, location, religion, finacial status and culture, as long as there is a good source of water supply).

    Description: The role of women in inland fishing communities in Nigeria have not been assessed or fully appreciated in the fishing industry in Nigeria. The role of women in the fisheries sub-sector is significant mainly in the post harvest activities such as sorting, preservation, processing, distribution and marketing of the fish products. The review highlights the fact that women not only make meaningful contribution to the socio-economic well-being of their households and the fishing but are also involved in other livelihood activities useful to their households and the community in which where they live. However, there are some constraints limiting women's involvement in fisheries and these range from socio-cultural, psychological to economic factors. It was therefore recommended that extension programmes on development issues should focus extensively on the post-harvest and livelihood activities in which women in inland fishing communities are mostly involved.
