    Description: The impact of recent changes in climate on the arctic environment and its ecosystems appear to have a dramatic affect on natural populations (National Research Council Committee on the Bering Sea Ecosystem 1996) and pose a serious threat to the continuity of indigenous arctic cultures that are dependent on natural resources for subsistence (Peterson D. L., Johnson 1995). In the northeast Pacific, winter storms have intensified and shifted southward causing fundamental changes in sea surface temperature patterns (Beamish 1993, Francis et al. 1998). Since the mid 1970’s surface waters of the central basin of the Gulf of Alaska (GOA) have warmed and freshened with a consequent increase in stratification and reduced winter entrainment of nutrients (Stabeno et al. 2004). Such physical changes in the structure of the ocean can rapidly affect lower trophic levels and indirectly affect fish and marine mammal populations through impacts on their prey (Benson and Trites 2002). Alaskan natives expect continued and perhaps accelerating changes in resources due to global warming (DFO 2006).and want to develop strategies to cope with their changing environment.

    Boat wakes and their influence on erosion in the Atlantic Intracoastal Waterway, North Carolina (2021)
    NOAA/National Centers for Coastal Ocean Science | Beaufort, NC

    Description: Boat wakes in the Atlantic Intracoastal Waterway (AIWW) of North Carolina occur in environments not normally subjected to (wind) wave events, making sections of AIWW potentially vulnerable to extreme wave events generated by boat wakes. The Snow’s Cut area that links the Cape Fear River to the AIWW is an area identified by the Wilmington District of the U.S. Army Corps of Engineers as having significant erosion issues; it was hypothesized that this erosion could be being exacerbated by boat wakes. We compared the boat wakes for six combinations of boat length and speed with the top 5% wind events. We also computed the benthic shear stress associated with boat wakes and whether sediment would move (erode) under those conditions. Finally, we compared the transit time across Snow’s Cut for each speed. We focused on two size classes of V-hulled boats (7 and 16m) representative of AIWW traffic and on three boat speeds (3, 10 and 20 knots). We found that at 10 knots when the boat was plowing and not yet on plane, boat wake height and potential erosion was greatest. Wakes and forecast erosion were slightly mitigated at higher, planing speeds. Vessel speeds greater than 7 knots were forecast to generate wakes and sediment movement zones greatly exceeding that arising from natural wind events. We posit that vessels larger than 7m in length transiting Snow’s Cut (and likely many other fetch-restricted areas of the AIWW) frequently generate wakes of heights that result in sediment movement over large extents of the AIWW nearshore area, substantially in exceedance of natural wind wave events. If the speed, particularly of large V-hulled vessels (here represented by the 16m length class), were reduced to pre-plowing levels (~ 7 knots down from 20), transit times for Snow’s Cut would be increased approximately 10 minutes but based on our simulations would likely substantially reduce the creation of erosion-generating boat wakes. It is likely that boat wakes significantly exceed wind wave background for much of the AIWW and similar analyses may be useful in identifying management options.

    Description: Remotely operated vehicle (ROV) surveys were conducted from NOAA’s state-of-the-art Fisheries Survey Vessel (FSV) Bell M. Shimada during a six-day transit November 1-5, 2010 between San Diego, CA and Seattle, WA. The objective of this survey was to locate and characterize deep-sea coral and sponge ecosystems at several recommended sites insupport of NOAA’s Coral Reef Conservation Program. Deep-sea corals and sponges were photographed and collected whenever possible using the Southwest Fisheries Science Center’s (SWFSC) Phantom ROV ‘Sebastes’ (Fig. 1).The surveyed sites were recommended by National Marine Sanctuary (NMS) scientists at Monterey Bay NMS, Gulf of the Farallones NMS, and Olympic Coast NMS (Fig. 2). The specific sites were: Sur Canyon, The Football, Coquille Bank, and Olympic Coast NMS. During each dive, the ROV collected digital still images, video, navigation, and along-track conductivity-temperature-depth (CTD), and optode data. Video and high-resolution photographs were used to quantify abundance of corals, sponges, and associated fishes and invertebrates to the lowest practicable taxonomic level, and also to classify the seabed by substrate type. A reference laser system was used to quantify area searched and estimate the density of benthic fauna.

    Description: We have recently exchanged and integrated into a single database tag detections for conch, teleost and elasmobranch fish from four separately maintained arrays in the U.S. Virgin Islands including the NMFS queen conch array (St. John nearshore), NOAA’s Biogeography Branch array (St. John nearshore & midshelf reef); UVI shelf edge arrays (Marine Conservation District, Grammanik & other shelf edge); NOAA NMFS Apex Predator array COASTSPAN (St. John nearshore). The integrated database has over 7.5 million hits. Data is shared only with consent of partners and full acknowledgements. Thus, the summary of integrated data here uses data from NOAA and UVI arrays under a cooperative agreement.The benefits of combining and sharing data have included increasing the total area of detection resulting in an understanding of broader scale connectivity than would have been possible with a single array. Partnering has also been cost-effectiveness through sharing of field work, staff time and equipment and exchanges of knowledge and experience across the network. Use of multiple arrays has also helped in optimizing the design of arrays when additional receivers are deployed. The combined arrays have made the USVI network one of the most extensive acoustic arrays in the world with a total of 150+ receivers available, although not necessarily all deployed at all times. Currently, two UVI graduate student projects are using acoustic array data.

    Description: In May 2006, the NOAA National Ocean Service (NOS), in conjunction with the EPA National Health and Environmental Effects Laboratory (NHEERL), conducted an assessment of the status of ecological condition of soft-bottom habitat and overlying waters throughout the mid-Atlantic Bight (MAB) portion of the eastern U.S. continental shelf. The study area encompassed the region from Cape Cod, MA and Nantucket Shoals in the northeast to Cape Hatteras in the south, and was defined using a one nautical mile buffer of the shoreline extended seaward to the shelf break (~100-m depth contour). A total of 50 stations were targeted for sampling using standard methods and indicators applied in prior NOAA coastal studies and EPA’s Environmental Monitoring and Assessment Program (EMAP) and National Coastal Assessment (NCA). A key feature adopted from these studies was the incorporation of a random probabilistic sampling design. Such a design provides a basis for making unbiased statistical estimates of the spatial extent of ecological condition relative to various measured indicators and corresponding thresholds of concern. Indicators included multiple measures of water quality, sediment quality, and biological condition (benthic fauna). Through coordination with the NOAA Fisheries Service/Northeast Fisheries Science Center (NFS/NEFSC), samples of summer flounder (Paralichthys dentatus) also were obtained from 30 winter 2007 bottom-trawl survey stations in overlapping portions of the study area and used for analysis of chemical-contaminant body burdens.

    An investigation of survey technologies and modeling techniques for improving deepwater surveys of nonindigenous species in the Northwestern Hawaiian Islands (2021)

    Description: Nonindigenous species (NIS) are a major threat to marine ecosystems, with possible dramatic effects on biodiversity, biological productivity, habitat structure and fisheries. The Papahānaumokuākea Marine National Monument (PMNM) has taken active steps to mitigate the threats of NIS in Northwestern Hawaiian Islands (NWHI). Of particular concern are the 13 NIS already detected in NWHI and two invasive species found among the main Hawaiian Islands, snowflake coral (Carijoa riseii) and a red alga (Hypnea musciformis).Much of the information regarding NIS in NWHI has been collected or informed by surveys using conventional SCUBA or fishing gear. These technologies have significant drawbacks. SCUBA is generally constrained to depths shallower than 40 m and several NIS of concern have been detected well below this limit (e.g., L. kasmira – 256 m) and fishing gear is highly selective. Consequently, not all habitats or species can be properly represented.Effective management of NIS requires knowledge of their spatial distribution and abundance over their entire range. Surveys which provide this requisite information can be expensive, especially in the marine environment and even more so in deepwater. Technologies which minimize costs, increase the probability of detection and are capable of satisfying multiple objectives simultaneously are desired.This report examines survey technologies, with a focus on towed camera systems (TCSs), and modeling techniques which can increase NIS detection and sampling efficiency in deepwater habitats of NWHI; thus filling a critical data gap in present datasets. A pilot study conducted in 2008 at French Frigate Shoals and Brooks Banks was used to investigate the application of TCSs for surveying NIS in habitats deeper than 40 m. Cost and data quality were assessed. Over 100 hours of video was collected, in which 124 sightings of NIS were made among benthic habitats from 20 to 250 m. Most sightings were of a single cosmopolitan species, Lutjanus kasmira, but Cephalopholis argus, and Lutjanus fulvus, were also detected.The data expand the spatial distributions of observed NIS into deepwater habitats, identify algal plain as an important habitat and complement existing data collected using SCUBA and fishing gear. The technology’s principal drawback was its inability to identify organisms of particular concern, such as Carijoa riseii and Hypnea musciformis due to inadequate camera resolution and inability to thoroughly inspect sites. To solve this issue we recommend incorporating high-resolution cameras into TCSs, or using alternative technologies, such as technical SCUBA diving or remotely operated vehicles, in place of TCSs. We compared several different survey technologies by cost and their ability to detect NIS and these results are summarized in Table 3.

    Description: This report presents the results of a two-year investigation and summary of oceanographic satellite data obtained from multiple operational data providers and sources, spanning years of operational data collection. Long-term summaries of Sea Surface Temperature (SST) and SST fronts, Sea Surface Height Anomalies (SSHA), surface currents, ocean color chlorophyll and turbidity, and winds are provided.Merged satellite oceanographic data revealed information on: (1) seasonal cycles and timing of transition periods; (2) linkages between seasonal effects (warming and cooling), upwelling processes and transport; and (3) nutrient/sediment sources, sinks, and physical limiting factors controlling surface response for Olympic Coast marine environments. These data and information can be used for building relevant hind cast models, ecological forecasts, and regional environmental indices (e.g. upwelling, climate, “hot spot”) on biological distribution and/or response in the PNW.

    Wave forecasts associated with hurricane landfalls in the vicinity of Cape Lookout, North Carolina (2021)

    Description: Hurricanes can cause extensive damage to the coastline and coastal communities due to wind-generated waves and storm surge. While extensive modeling efforts have been conducted regarding storm surge, there is far less information about the effects of waves on these communities and ecosystems as storms make landfall. This report describes a preliminary use of NCCOS’ WEMo (Wave Exposure Model; Fonseca and Malhotra 2010) to compute the wind wave exposure within an area of approximately 25 miles radius from Beaufort, North Carolina for estuarine waters encompassing Bogue Sound, Back Sound and Core Sound during three hurricane landfall scenarios. The wind wave heights and energy of a site was a computation based on wind speed, direction, fetch and local bathymetry. We used our local area (Beaufort, North Carolina) as a test bed for this product because it is frequently impacted by hurricanes and we had confidence in the bathymetry data. Our test bed conditions were based on two recent Hurricanes that strongly affected this area. First, we used hurricane Isabel which made landfall near Beaufort in September 2003. Two hurricane simulations were run first by passing hurricane Isabel along its actual path (east of Beaufort) and second by passing the same storm to the west of Beaufort to show the potential effect of the reversed wind field. We then simulated impacts by a hurricane (Ophelia) with a different landfall track, which occurred in September of 2005. The simulations produced a geographic description of wave heights revealing the changing wind and wave exposure of the region as a consequence of landfall location and storm intensity. This highly conservative simulation (water levels were that of low tide) revealed that many inhabited and developed shorelines would receive wind waves for prolonged periods of time at heights far above that found during even the top few percent of non-hurricane events. The simulations also provided a sense for how rapidly conditions could transition from moderate to highly threatening; wave heights were shown to far exceed normal conditions often long before the main body of the storm arrived and importantly, at many locations that could impede and endanger late-fleeing vessels seeking safe harbor. When joined with other factors, such as storm surge and event duration, we anticipate that the WEMo forecasting tool will have significant use by local emergency agencies and the public to anticipate the relative exposure of their property arising as a function of storm location and may also be used by resource managers to examine the effects of storms in a quantitative fashion on local living marine resources.

    Description: The Working Group on Iron Supply and its Impact on Biogeochemistry and Ecosystems in the North Pacific Ocean (WG 22) was established October 2007 under the direction of the Biological Oceanography Committee (BIO) and consisted of 20 members from all PICES member countries, including Co-Chairmen, Drs. Shigenobu Takeda (Japan) and Fei Chai (USA). The purpose of the Working Group was to examine the role of iron biogeochemistry and its impact on biological productivity and marine ecosystems. WG 22 has completed the following four goals in its terms of reference:1. Compile and synthesize available iron biogeochemistry data in the North Pacific;2. Review the past and ongoing laboratory, field and modeling studies on iron biogeochemistry and its impact on biological productivity and marine ecosystems in the North Pacific Ocean;3 Determine the natural supplies of iron to the North Pacific, which include atmospheric dust transport and movement of iron-enriched waters, and examine linkages between iron supply and ecosystem responses;4. Identify gaps and issues related to experimental and modeling activities, encourage and plan national and international scientific programs on iron biogeochemistry and its impact on marine ecosystems in the North Pacific.WG 22 has accomplished most of its originally proposed objectives. Through Annual Meetings, we kept the iron community in all PICES member countries together on a regular basis. Our Working Group members actively exchanged ideas and discussed their ongoing research results, which led to several important publications. We also consolidated some of available iron data for the North Pacific, and more data will be added to this data set as time goes on. We are confident that our short 3-year effort will provide a sound foundation for future iron-related research in the North Pacific Ocean.

    Description: The kilishi of Heterotis niloticus was produced for determination of appropriate slurry formulations for fish kilishi preparation. Thirty six freshly caught samples of H. niloticus with average weight of 306.20 ~c 18.33g, kilishi of this species was prepared with three different slurry formulations of high (F1), medium (F2) and low (F3) proportions of groundnut dough to spice mixture in the ratio of 1.3: 1.0, 1.0: 1.2 and 1.0: 1.8, respectively. Results of proximate composition indicated that kilishi of the H. niloticus prepared with formulation 3 (F3) recorded significantly higher (p〈0.05) protein content (54.22 ~c 0.01 %) and lower lipid content (8.00 ~c 0.00%), despite recording significantly higher (p〈0.05) moisture content (9.93 ~c 0.07%). Sensory score of kilishi of H. niloticus processed with F3 formulation rated significantly higher (p〈0.05) for taste, flavour and general acceptability with mean scores of 5.94 ~c 0.21,5.77 ~c 0.20 and 5.50 ~c 0.22, respectively. It could be concluded that kilishi of H. niloticus prepared with F3 formulation was the most acceptable hence, recommended for use in kilishi production.

    Description: The microbial load of four different fish species from five different market locations in Ibadan metropolis were determined using standard microbiological procedures. The bacteria count of fish sampled from Ojo market was the highest while the bacteria count of the fish sample from Bodija market was the lowest. There was no significant difference (p〈0.05) in the microbial load of the fish sampled from various market locations in Ibadan metropolis. Similarly, there was no significant difference (p〉0.05) in the microbial load on various fish species sold in Ibadan metropolis. The isolated bacteria from the study were: E. coli, Salmonella spp, Klebsiella spp, Staphylococcus aureus, Aerosomonas spp, Pseudomonas spp, Vibrio spp, Serratia spp, Chromobacterium spp, Enterobacteria spp and Shigella spp. The fungi count of fish sampled from Omi markets was the highest while the fungi count of the fish sampled from Ojo market was the lowest. The following fungi were however isolated from the study: Aspergillus flavus, Penicillium spp, Fusarium oxysporum, Trrichoderma spp and Ceotrichium albidium. The study shows that reheating may be necessary to destroy or inactivate micro-organisms in smoked fish before consumption.

    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: Fish is one of the most nutritious diet on earth, and contributes a considerable proportion of its protein to the Nigerian populace. Fifty-four specimens composing of six samples from each species, were analyzed in frozen and smoked states, monthly. Each set of six specimens were cut into two equal parts and randomly re-arranged into two groups. One group was smoked while the other was preserved in the freezer (at-2~'C) for 5 days. The highest moisture content was observed in frozen samples of Mormyrops deliciosus thus: (77.14 ~c 11.05%). Smoked O. niloticus had the highest protein content (26.79 ~c 0.74%) while the least was observed in frozen Mormyrops deliciosus (13.37 ~c 2.57%). Smoked samples of Oreochromis niloticus recorded the highest fat content accounting for a value of (25.97 ~c 0.51 %) while the least was observed in frozen Mormyrops deliciosus (7.97 ~c 0.45%). It could be concluded that while frozen samples loosed nutrient, smoked ones gained nutrients in all three species. The study recommends that fish be consumed in their smoked state, in preference to frozen ones, in response to higher nutritive value. Oreochromis niloticus which recorded the highest nutritive value in crude protein content, should be consumed more, followed by Labeo coubie and Mormyrops deliciosus in that order.

    Description: The study was conducted to determine the toxicity of unripe Ackee apple (Blighiasapida) fruit extract on catfish, Clarias gariepinus fingerlings using the 96-hour bioassay under laboratory condition. The LC50 was determined graphically as 3.00ppt. Mean mortality was 0, 40, 50, 70 and 80% in the concentrations of 0, 3.33, 3.47,3.60 and 3.73ppt. Statistical analysis of the results showed that there were significant differences (P〈0.05) on the effect of concentration. Mortality increased with increase in concentration of toxicant and duration of exposure. Clarias gariepinus showed erratic swimming pattern, loss of reflex which increased with increase in concentration. Histopathological changes were revealed in the gills, skin and heart of the fish. The gill structure was altered and there were moderate mucosal erosion. There were several lymphoid aggregations with fibrous connective tissue at the dermal and epidermal areas in the skin. The heart myofibre were diffusely disintegrated with edema between bundles.

    Description: Completely randomized design with duplicate groups were used to study the growth performance of 400 fingerlings of Clarias gariepinus in 2m x 2m x 1m concrete tanks in an out-door hatchery complex of National Institute for Freshwater Fisheries Research (NIFFR), New Bussa, Niger State, Nigeria. Graded levels (0, 1,2,3 or 4) % of yeast (Saccharomyces cerevisiae) was included into a 40% crude protein (C.P) NIFFR floating basal diet and fed to Clarias gariepinus in tanks for 16 weeks and 35% in the last 4 weeks. This was to determine the optimum level of supplemental yeast inclusion as a floater additive into diets of C. gariepinus and to quantify feed and its cost for raising a kilogram of the fish fed diets. The experiment was geared towards development of cost effective standard floating feed for Clarias gariepinus. There was no significant difference in weight gain (WG), feed consumed (FC), specific growth rate (SGR), survival, cost of feed consumed (CFC) and palatability test of flesh (P〉0.05) except FCR (P〈0.05) and feed cost per kilogram of fish (P〈0.05) at the end of 8 and 20 weeks. There was no histopathological defect observed on the fish and fish carcass. It was concluded that 2% or 1 % level of yeast can be included in NIFFR floating feed with the assurance of producing a kilogram of C. gariepinus with a feed of N300.00 under good management practices based on ingredient ruling price at the time of this study and this might be capable of increasing farmer's income in fish production.

    Description: A feeding trial was conducted to determine the effect of biscuit waste meal on the growth performance and utilization of Clarias gariepinus juveniles. A total of 300 juveniles of average weight 8.85g were randomly divided into 5 Treatments, each with three replicates. Twenty juveniles were distributed into fifteen happas (0.7m3) and each happa was suspended to 3/4 of its volume using kuralon ropes carefully tied round the bamboo poles across the concrete tanks. Five diets containing 40% crude protein were formulated in which maize was replaced with biscuit waste meal at Treatment diet 1 (TD1) 0%, 25% (TD2), 50% (TD3), 75% (TD4), 100% (TD5) levels.The juveniles were fed at 3% body weight per day for 10 weeks. It was recorded at the end of the experiment that biscuit waste was most suitable as an energy supplement when incorporated at 25% replacement (TD2) with maize. TD1 had the highest weight gain followed by TD2, TD3, TD4 and TD5 respectively. There were no significant differences (P〉0.05) in the growth response in TD1 (0%), T0D (25%) and TD3 (50%). It is therefore concluded that biscuit waste meal is a cheap source of non conventional energy source which can be used favorably to replace maize (25% inclusion level) as an energy source in the diets of Clarias gariepinus.

    Description: Heterobranchus longifilis juveniles (93.42 - 147.77g) used for this study were product of an indoor experiment in glass aquaria transferred to outdoor tanks. This study is therefore, a continuation of the indoor study using the same feed for the fish outdoors for 230 days. They were stocked in ten concrete tanks, of sizes 2m X 2m. The fish were stocked according to the number harvested from the indoor experiment for each treatment. The experimental diets were prepared with fish meal, soybean, groundnut cake, wheat offal, yeast, premix, starch, vitamin C and Vitamin B-complex to meet the requirement of H. longifilis. The analyzed crude protein in each diet was 42.56%, 43.32%, 4369%,43.86% and 43.98%. There was significant variation (p〈0.05) in the Mean Final Weight (MFW), Mean Weight Gain (MWG), Protein Efficiency Ratio (PER), Specific Growth Rate (SGR) and Percentage Survival (PS). The survival of the fish was highest with the fish fed 2g yeast/I00g of diet and this was not significantly different from fish fed 1g yeast/ 100g diet. The cost of production of one kilogram of fish using varying levels of S. cerevisiae in diets varied significantly (p〈0.05).

    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: This study investigates the use of Luffa cylindrica seed meal as soybean replacer in the diet of Clarias gariepinus. Five isonitrogenous diets containing soybean meal which was replaced by Luffa cylindrica at a rate of 0, 15,30,45 and 60% were made. The diets without Luffa cylindrical seed meal served as the control. Experimental diets were assigned randomly to the tanks and each group of fish was fed 5% body weight in equal proportion per day. The fish fed diet 1 had the highest incidence of cost, while the fish fed diet 4 had the lowest incidence of cost. There was no significant difference (P〉0.05) in the incidence of cost of producing 1kg fish with the different dietary treatments. The fish fed at diet 4 had the highest profit, while the fish fed at diet 1 had the lowest profit. There was no significant difference (P〉0.05) in the profit margin of producing 1kg fish with the different dietary treatments. The incidence of cost showed that it was cheaper to produce 1kg of fish with Luffa cylindrical seed meal because feeding the fish with the diet (control and tests diets) left some profit margin.

    Description: A 56-day feeding trial to investigate the effects of feeding varying levels of substituted Soybeam meal (SBL) with Pigeon pea seed meal (PSM) on the performance and carcass characteristics of Clarias gariepinus was conducted. Five isonitrogenous 40% crude protein diets were formulated where PSM Clarias gariepinus (15.74 ~c 1.22g) stocked at 15 fish/50 litres tanks were fed diets in triplicates twice daily to satiation and weight changes recorded weekly. Fish fed diet with 25% and 100% PSM inclusion gave the highest mean weight gain of 25.47g and 23.34g respectively (P〉0.05). There were no significant difference (P〉0.05) among the weight gain of other treatments. Fish fed diet containing 0% SBM and 100% PSM gave the highest gross food conversion efficiency and percentage weight gain of 43.50g and 12.l8g while fish fed diet containing 50% SBM and 50% PSM had the lowest of 35.67 and 9.99 respectively with no significant changes compared with other treatments. For good growth, fish farmers are advised to consider Pigeon pea seed meal either as a partial (25%) or total replacement (100%) for soybean meal in the diet of Clarias gariepinus juveniles.

    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: The culture of tilapia is assuming a greater importance globally. However, Nigeria's contribution to global production is insignificant. Although Egypt and Nigeria were the only African countries that had record of tilapia production in 1950, Egypt has left Nigeria far behind. The problem of prolific breeding still persists in our farm, making it difficult to raise tilapia to a good market size. The paper reviews Nigeria fish production, supply and demand forces and the contributions of leading tilapia producers; namely China, Thailand, Indonesia Egypt to mention a few. It reiterates some of the credentials of tilapia that makes it a good candidate for culture, the species for culture and the place of tilapia in the world fish market. The paper examines some of the limiting factor hindering the development of tilapia Industry and ways of mitigating such factors.

    Description: The effect of proviron tablets (1a-methyl androsterone) as a masculinization agent was tried on frys of Oreochromis niloticus (Nile Tilapia). 900 Healthy four (4) day old fry of Oreochromis niloticus (D XVII -XVIII, 12-14; A III, 8-10) with mean initial length 1.0cm and mean initial weight 0.0153g were subjected to two feeding treatments. Treatment one (T〈sub〉1〈/sub〉) replicated twice, consisted of 150 fry in a 100L capacity circular plastic basin containing 35 Litres of clean borehole water. Treatment Two (T〈sub〉2〈/sub〉) replicated 4 times contained 150 fry each in similar environment as T〈sub〉1〈/sub〉, however the replicates were fed a starter blended hormone diet containing 60mg of hormone per kilogram of coppens feed. All the treatments were fed at 20% body weight the first week and reduced by 5% weekly till the 4th week. The experimental fishes were transferred from their replicate basins to 6 hapas measuring 1m x 1m x 1m submersed in a concrete pond of dimension 5m x 8m x 1.5m containing algae. The fishes in the hapas fed adlibitum on algae and non-treated 2mm coppens supplementary feed. The result showed that a sample of 164 hormone treated dead fry in the 3rd week following mass mortality were all male. Also when the experiment was terminated in the 9th week all 406 hormone treated fish in 4 hapas were all male (100%). The sex ratio in the 236 untreated fish was 110 males (46.61%) and 126 females (53.39%). The mean weight gain and specific growth rate (SGR) in parenthesis for the sexes in different treatments was: Hormone treated males 4.66g (3.94), untreated males 4.52g (3.92) and untreated females 4.16g (3.87). It was concluded that proviron (la-methylandrosterone) can achieve 100% sex reversal in Oreochromis niloticus and used in place of methyltestosterone, and that hormone treated males grew faster and bigger than untreated males and females. Research on the effect of different doses of proviron on sex reversal of Nile tilapia was recommended.

    Description: Mudcatfish (Heterobranchus longifilis) juveniles (body weight 61.60-83.05g, length 204.43 ~c 3.07 - 229.53 ~c 3.65mm) were fed with diet containing crude protein (CP) levels of 30%,35% and 40% for 10 weeks, using fishmeal as a protein source. Growth performance and feed utilization were investigated. Fish were raised in plastic aquaria of dimension 46 x 38 x 28cm3 at a temperature range of 26.0-29.0~'C, pH value of 6.6-7.4 and dissolved oxygen of 3.5-5.1 mg/1. The highest increase in body weight (23.30 ~c 4.30g) and specific growth rate (0.68 ~c 0.02% day-1) were achieved with Diet 2 (35%CP). The condition factor ranged 0.60 ~c 0.009- 0.66 ~c 0.005 and fish survival was 100% for all diets. Protein efficiency ratio (2.37 ~c 0.35) was also significantly better with 35% CP (p〈0.001). Diets 1(30% CP) and 2 (40% CP) gave lower performances. The observations in this study suggest that a 35% high quality protein diet will probably provide the needed protein requirement for H.longifilis juveniles.

    Description: The effects of two different preservative methods, NIOMR Smoking Kiln and Oven drying on Crude Protein minerals and Vitamin of clarias gariepinus were studied. Clarias gariepinus were obtained from the fish farm of African Regional Aquaculture Centre, Aluu, Port Harcourt. The crude protein, minerals and vitamins of the fresh fish were determined immediately while two other batches were separately dried using oven at 50~'C for 30minutes and NIOMR Smoking Kiln at 70~'C for 3 hours. Result of the crude protien of fresh fish was 21.84 ~c 1.10 which increased to 59.53 ~c 1.88 and 35.41 ~c 1.00 in both NIOMR smoking and oven, respectively. This means that, there was a significant different in both dryers on the crude protein. This will improve the knowledge and capacity of rural women and agricultural communities on the appropriate processing method for fish. The mineral and vitamins of oven dried and NIOMR Smoking kiln were analyzed. The vitamin content of both the fish, dried and smoking kiln shows no significant different except in vitamin A which was significant (p〈0.05).There was significant different (p〈0.05) in the mineral content of the two different drying method except in sodium, Potassium and Phosphorus of the drying method. This result indicates that the two drying methods have effects on the nutritional quality of catfish.

    Description: The objective of this study was to determine the quality deterioration of African catfish Clarias gariepinus and Tilapia, Orechromis niloticus stored at-4~'C for 8 weeks. Weekly analysis was conducted to measure protein, moisture, crude fat and ash content and evaluation of the sensory quality. The result clearly reveals that during storage, both the samples showed a highly significant (p〈0.05) decreasing trend in protein, lipid, ash and moisture content. The result shows that protein, moisture, fat and ash content of the fish samples decreases with increasing duration of frozen storage. The fresh samples has the highest value of protein, moisture, fat and ash content while the least value was recorded on the 8th week. 19.98 ~c 2.66%, 80.71 ~c 1.65%, 3.92 ~c 0.5% and 2.52 ~c were recorded for freshly prepared Clarias gariepinus respectively while 12.62 ~c 1.22%, 66.86 ~c 0.68%, 1.08 ~c 1.04% and 1.14 ~c 0.33% were recorded on the 8th week respectively. 20.80 ~c 1.46, 60.75 ~c 2.50, 9.75 ~c 2.50% and 5.85 ~c 2.51% were recorded for freshly prepared Oreochromis niloticus respectively while 25.05 ~c 2.20%, 47.60 ~c 2. 15%, 7.1 ~c 0.20 and 3.00 ~c 2.10% were recorded on the 8th week respectively. After 8 weeks, the total decrease was 7.36%, 13.85%, 2.84% and 1.38% respectively for Clarias gariepinus and 3.75%, 13.45%, 2.65% and 2.85% respectively for Oreochromis niloticus. Sensory evaluation of the fish samples revealed that quality, texture, colour, odour, aroma and taste decrease with increasing duration of storage and best quality obtained when freshly prepared.

    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: In the spring of 2010, the Government of Canada invited PICES to participate in a Commission of Inquiry into the Decline of Sockeye Salmon in the Fraser River by considering how marine ecology may have affected their abundance. A major objective that was achieved in this report was to assemble, within an eight week period, as comprehensive a summary as was possible of what is known about Fraser River sockeye salmon (Oncorhynchus nerka) in the ocean. While much of this effort involved summarizing information published in data/technical reports and the primary literature, where necessary, original data have been re-examined and new analyses conducted to fulfill the terms of the Statement of Work. The compilation provides a background of knowledge against which to judge what can be known regarding the two major questions posed by the Cohen Commission to PICES:-Can the decline in Fraser River sockeye in 2009 be explained by the conditions the fish experienced in the marine environment?-Is there any evidence for declines in marine productivity or changes in Fraser River sockeye distribution that can be associated with the 15-year gradual decrease in Fraser River sockeye productivity?

    Description: This report is a summary of the activities that WG 24 undertook from 2009 to 2012. The Working Group, with the guidance of FIS and MEQ, refined the activities under the terms of reference so that each PICES member country with active Working Group members could contribute to the report. This refinement was required due to the different types of expertise needed to meet the three very different activities outlined in the terms of reference.Through topic sessions, workshops and targeted Working Group activities, different aspects of sustainable marine aquaculture research relevant to WG 24’s terms of reference were highlighted. Research activities in all PICES member countries focus on identifying aquaculture–environment interactions, whether to model the impacts or to minimize them through optimizing culture approaches, as well as on research related to disease identification and management.Based on the experience of WG 24 and the direction of PICES under its FUTURE science plan, some marine aquaculture issues and analysis can be more holistically addressed through expert groups that include consideration of anthropogenic stressor effects on the marine environment. Additionally, any future marine aquaculture-related PICES expert group should be more narrowly focused to not only allow for more directed work, but also to increase the likelihood of experts from all PICES member countries being able to participate and contribute.This report is composed of three sections: Assessing environmental interactions of marine aquaculture, marine aquaculture legislative frameworks and environmental interactions research, and pathogens of aquatic animals organized as country reports.

    Description: In October 2007, the PICES Working Group on Comparative Ecology of Krill in Coastal and Oceanic Waters around the Pacific Rim (WG 23) was established under the direction of the Biological Oceanography Committee. This report brings together reviews of the state of knowledge of Euphausia pacifica and Thysanoessa species in the six PICES member countries over the time period from 2008 to 2012. The chances to conduct euphausiid research varied amongst countries, but PICES scientists rose to the challenge and made the most of the opportunities available to them. From mining euphausiid data out of existing time-series data sets to conducting live euphausiid experiments (using the protocol available on the PICES website, http://www.pices.int/projects/Euphasiid/euphasiid.aspx), WG 23 members generated new and interesting data on euphausiids throughout the North Pacific.

    Description: In 2008, the North Pacific Marine Science Organization (PICES) and the International Council for the Exploration of the Sea (ICES) approved the formation of an interdisciplinary Working Group on Forecasting Climate Change Impacts on Fish and Shellfish (WG-FCCIFS). This Working Group was designed to enagage the PICES and ICES scientific communities in an effort to discuss and assess our current understanding of the implications of climate change on marine fish and fisheries. The group was quite active, and the products of WG-FCCIFS include one major scientific symposium, a symposium volume and several peer reviewed journal articles. WG-FCCIFS’s primary accomplishments and research findings are described in this report. The group promoted research on climate change impacts on marine ecosystems by scientists in PICES and ICES member countries through coordinated communication, exchange of methodology, and organization of meetings to discuss and publish results. In collaboration with relevant expert groups in PICES and ICES, WG-FCCIFS developed frameworks and methodologies for projecting the impacts of climate change on marine ecosystems, with particular emphasis on shifts in the distribution, abundance and production of commercial fish and shellfish. WG-FCCIFS members met to review the results of designated case studies to test methods. Given the limitations of our forecasts, they also explored techniques for estimating and communicating uncertainty in forecasts and strategies for research and management under climate change scenarios. As the 3-year term for WG-FCCIFS approached, it was clear that PICES and ICES were well positioned to serve as world leaders in advancing science on assessments of climate change impacts on marine ecosystems. This recognition led to the formation of the ICES Strategic Initiative on Climate Change Effects on Marine Ecosystems (SICCME), referred to as the Section on Climate Change Effects on Marine Ecosystems (S-CCME) within PICES.

    Description: The growth and survival of Clarias gariepinus larvae with an average length and weight of 6.0mm and 2.57mg respectively were fed commercial dry feed, decysted Artemia or copepods over a twelve day period. Larvae were hatched using the induced hormone technique. After endogenous feeding, 80 larvae were distributed into each of the nine tanks and fed ad libitum thrice a day. The highest growth rate and survival were observed in larva fed with decysted Artemia (p〈0.05). The present study showed that formulated diet may not be a suitable starter diet for Clarias gariepinus larvae.

    Description: The present study examined the utilization potential of date palm seed (DPS) as feed additive in the diet of African catfish Clarias gariepinus for efficient feed utilization. A total of 150 African catfish (weight ranged from 81.13 to 91.35 g) were divided into five experimental groups. The experiment was conducted for 70 days. Experimental diets were identical in all composition except for the variation in DPS level. Non-inclusion of DPS was used at 0% (control) and other levels are 0.5% (diet 2), 1.0% (diet 3), 1.5% (diet 4) and 2.0% (diet 5). The growth performance and nutrient utilization of African catfish including Weight Gain (WG), Specific Growth Rate (SGR), Protein Efficiency Ratio (PER) and Protein Productive Value (PPV) were significantly (p〈0.05) higher than those of fish fed control diets, where DPS supplementation at 1.5% appears to be generally higher than other levels. In the same trend fish fed diets with DPS supplementation produced improved fish carcass values and the haematology of fish was generally better from diets in all DPS fed fish. Overall production performance and subsequent fish quality assessments indicated that the diets containing 1.5% DPS level recorded the best performance in African catfish compared to other levels including the control diet. Based on the result of the present study, it is concluded that date palm seed supplementation positively influenced growth performance and feed utilization of African catfish as well as ensuring their healthy status.

    Description: Fish species were investigated for 12 calendar months from March 2009 - February 2010 forthnightly using traps, gillnets and cast nets from three sampling stations in Ikpa River. Ornamental fish species were sorted out from the pooled samples. The findings revealed that out of the 2307 fish specimens sampled, 1074 specimens made up of 38 species and 19 families were of indigenous ornamental fish. The highest contributing family in terms of number of species is Cichlidae (10 species) whereas Schilbeidae (593 specimens; 55.21%) is the highest contributor in terms of total number of specimens sampled. This is followed by Mochokidae and Mormyridae with 4 species each and Cichlidae with 158 specimens (14.70%). At the species level, the highest contributor is Physalia pellueida (577 specimens;53.72%)and is followed by Erpetoichthys calabarcus (60 specimens; 5.59%). The least contributors were Heterobranchus bidorsalis, periophthalmus barbarus and Pelyicachromis pulcher (1 specimen; 0.09%). Twelve families recorded only one species each. These great potentials of ornamental fish have been left unexploited and hence, undeveloped. Several species of ornamental fish have been imported into and exported from Nigeria by businessmen. This paper therefore highlights the constraints and also make recommendations for the exploitation and development of ornamental fishery in Akwa Ibom State and its environs.

    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 total of 2,800 tilapia (Oreochromis niloticus) were stocked in seven duplicates 5 by 4 m2 earthen ponds in NIFFR Integrated Farm, New-Bussa, Niger-State. Raw and sterilized poultry manure of 0.13 to 0.52 kg/m3 concentrations were used to fertilize the ponds with the unfertilized ponds serving as control. The following bacteria were isolated from the cow dung manure; Escherichia coli, E. co1iOl57:H7, Aeromonas hydrophila,Salmonella typhi, Shigella dysenteriae and Staphylococcus aureus. The fish samples from the 0.13 and 0.26 kg/m3 sterilized manure fertilized ponds had zero count in the muscles while samples from other ponds had pathogens in their fish muscles. The study revealed that fish samples from sterilized manures were better in terms of microbial safety for fish productions hence sterilized manure are recommended for use in fish production to ensure the microbial safety of the fish, handlers and that of the consumers.

    Description: The comparative growth response of African catfish fingerlings (Clarias gariepinus) fed with three (3) local and three (3) imported feeds was studied in the Department of Biological Sciences, Ahmadu Bello University, Zaria between September and October, 2009 with the aim of establishing the best quality feed in terms of specific growth rate, total weight and percentage survival rate for a period of 8 weeks (56 days). One hundred and twenty (120) fingerlings of Clarias gariepinus and six commercial feeds with varying crude proteins namely Chivita, Aquaplus, Vital, Skrettings, Multifeeds and Coppens were used for the experiment. Some water quality parameters analyzed indicated temperature varied from 25.50 ~'C to 28.0 ~'C while pH and dissolved oxygen ranged from 6.6 to 7.2 and 6.3mg/l to 8.2mg/l respectively. The treatment shows significant difference in terms of mean weight gain, specific growth rates and survival rate. The lowest SGR was 0.31 and 0.89 the highest. Fish fed with Chivita and Coppens showed the best growth compared to other treatments.

    Description: This study on the growth performance of Clarias gariepinus fingerlings fed separately on zooplankton, coppens, aquaculture feed and a combination of Coppens and zooplankton lasted for 8 weeks. Ninety (90) three-week old Hatchery bred fingerlings of Clarias gariepinus used for the study were acclimated for three (3) days in a concrete tank measuring 1m x 1m and fed with fish meal, before commencement of the experiment. The fingerlings were grouped in tens into 9 concrete tanks measuring 1m x 1m x 1m. These tanks were further grouped into threes to give three treatments labelled A〈sub〉1〈/sub〉 - A〈sub〉3〈/sub〉, B〈sub〉1〈/sub〉 - B〈sub〉3〈/sub〉 and C〈sub〉1〈/sub〉 - C〈sub〉3〈/sub〉. Treatment I (A〈sub〉1〈/sub〉 - A〈sub〉3〈/sub〉) were fed with zooplankton, Treatment II (B〈sub〉1〈/sub〉 - B〈sub〉3〈/sub〉) were fed zooplankton and 3% body weight of coppens, while Treatment III (C〈sub〉1〈/sub〉 - C〈sub〉3〈/sub〉) was fed with 5% body weight of coppens only. Zooplanktons used were mainly rotifers, branchionus and Cyclops. Total length and weight of fish were measured weekly and used as growth indices. Data collected were analyzed using one way Analysis of variance and means separated by Duncan's Multiple Range Test. Results from the study revealed that Treatments II and III were not significantly different from each other (P〉0.05) for both length and weight, but were different from Treatment I (P〈0.05). Based on the result, Treatment II is preferred and is recommended, for use, as zooplankton feed supplement helps to reduce cost of production and still ensure optimal production.

    Description: An experiment was carried out to determine the effect of blood and fish meal based diets on the feeding rate of tilapia in concrete tank. Two diets formulated at 35% CP, with blood and fish meal as the test ingredients. The diets were fed to tilapia (25/tank, with average initial weight of 7.61g) at 1, 1.5 and 2.5% biomass, in three replicates, once daily, in a 2:3 factorial design. Result showed that under blood meal based diet, average weight gain, gain in total length, relative weight gain and specific growth rate increased from 1 to 1.5% biomass and reduced at 2.5% ( 10.61, 16.75, 14.51g; 1.84, 3.18, 2.86cm; 147.37, 238.42, 147.42%; and 0.61, 0.85, 0.64 %/day), respectively (p〈0.05). Under fish meal based diet, the same parameters increased as feeding rate increased from 1 to 2.5% biomass ( 8.25, 16.55, 29.09g; 2.38, 2.67, 4.35cm; 125.07, 213.79, 408.63% and 0.52,0.82, 1.10%/day), respectively, (p〈0.05). In conclusion, blood meal based diet at 35%CP requires a feeding rate of 1.5% biomass, while fish meal based diet requires at least 2.5% for tilapia production in concrete tanks.

    Description: A workshop was convened by the MODEL Task Team and held June 23-28, 1996, in Nemuro, Japan, to develop the modeling requirements of the PICES Climate Change and Carrying Capacity (CCCC) Program. It was attended by over 40 scientists from all member nations of PICES. The principalobjectives of the workshop were to • review the roles and limitations of modeling for the CCCC program; • propose the level of modeling required; and • provide a plan for how to promote these modeling activities.Secondary activities at the workshop included organisational meetings of the Regional comparisons(REX) and Basin-scale experiment (BASS) Task Teams, and a symposium by Japan-GLOBEC on “Development and application of new technologies for measurement and modeling in marineecosystems.” This report serves as a record of the proceedings of this workshop.

    Description: Ecosystem indicators are part of a larger process that considers policy-level goals for an ecosystem.Other elements include operational objectives and performance criteria. The eastern Bering Sea isadvanced in application of ecosystem-based considerations to the management of marine resources. Forinstance, an Ecosystem Considerations appendix is prepared by the Alaska Fisheries Science Center(AFSC) each year for the annual Stock Assessment and Fishery Evaluation (SAFE) reports published bythe North Pacific Fishery Management Council (NPFMC). This report is reviewed annually byNPFMC’s plan teams and Scientific and Statistical Committee, and scientific advice is provided annuallyto managers based on ecosystem trends relative to managed fish species. Similarly, the North PacificMarine Science Organization (PICES) prepared a North Pacific Ecosystem Status report in 2004 and isbeginning to plan for an updated version of this report. Both reports can be improved by developingconsensus on operational objectives and appropriate indicators.Progress toward operational objectives and development of appropriate indicators was made byconducting the following four activities during an international workshop held on June 1–3, 2006, inSeattle (Washington, U.S.A.):1. Involve the Bering Sea and international communities in developing of a set of operational objectivesfor the southeastern Bering Sea ecosystem;2. Evaluate two status reports with the goal of integrating results and streamlining the presentation. Thetwo reports are:a. NPFMC. 2005. Appendix C: Ecosystem Considerations for 2006. North Pacific FisheryManagement Council, Anchorage, Alaska (http://access.afsc.noaa.gov/reem/EcoWeb /index.cfm);b. PICES. 2004. Marine Ecosystems of the North Pacific, PICES Special Publication 1, 280 p.(http://www.pices.int/publications/special_publications/NPESR/2005/npesr_2005.aspx);3. Investigate methodologies that monitor system-wide structural changes within the marine ecosystem;4. Identify steps to validate indicator performance, improve the monitoring network, and integrate intopredictive models.In preparing the workshop a focus was on the southeastern Bering Sea because it represents the center ofthe Bering Sea/Aleutian Islands large marine ecosystem (LME), one of three LMEs (the other two are theGulf of Alaska and Arctic Ocean) defining the North Pacific Research Board’s (NPRB) research region.This endeavour was funded by NPRB. Although the project focused on the southeastern Bering Sea, theintent of this exercise was to provide insights, findings, and recommendations more broadly applicable tothe North Pacific and its adjacent seas, a larger area representing the PICES region, including watersbordering China, Japan, South Korea, Russia, Canada, and the United States.Workshop presentations included three white papers on (1) development of operational objectives for thesoutheastern Bering Sea ecosystem; (2) ecosystem-based management for the oceans: a perspective forfisheries in the Bering Sea; and (3) ecological indicators: software development. These papers werefollowed by presentations on indicator use in other regions with advice for the North Pacific and reportson the status of the southeastern Bering Sea. A series of break-out groups was then convened to discussthe Ecosystem Considerations appendix of the SAFE report and PICES North Pacific Ecosystem Statusreport, objectives and use of indicators, matching indicators to objectives, methods to monitor ecosystemwidestructural changes, and means toward communicating results. Although this project was ambitious,substantial progress was made, and the following recommendations resulted from the workshop:Ecosystem Objectives and Indicators1. Ecosystem-level and community-level conservation thresholds are relatively new ideas in marineconservation. Since they will require new kinds of indicators, research is needed for theirdevelopment and application to the Bering Sea.2. New research is needed to understand how to synthesize the large set of Bering Sea data records intoa reasonable number of ecosystem status indicators.3. A formal process of evaluating and selecting ecosystem indicators is a general requirement. TheAlaska Fisheries Science Center should consider developing and applying such a process to theindicators in its Ecosystem Considerations appendix.4. Enhancements to the ocean/ecosystem monitoring network are needed to fill data gaps at ecologicalpulse points (plankton, benthic infauna and epifauna, seasonal species interactions and movements,small pelagics, and cephalopods) to improve predictive models and the development of ecosystemindicators.5. More collaboration between modelers at the Alaska Fisheries Science Center and the Pacific MarineEnvironmental Laboratory, and elsewhere is encouraged to link various climate/ecosystem andconservation/assessment models, and to use these models to evaluate management strategies.Socio-economicsWhile the workshop did not address socio-economic operational objectives for the Bering Sea and NorthPacific, linkages between the well-being of people and healthy marine ecosystems require a level ofattention comparable to those for ecosystem conservation objectives:6. Socio-economic objectives related with the marine environment should be developed for the region,along with their indicators and reference points.7. The North Pacific Fishery Management Council should play a central role in shepherding thedevelopment of these socio-economic objectives and indicators for the southeastern Bering Sea andGulf of Alaska ecosystems;8. There is a need to conduct scientific and policy analyses of pathways to achieve socio-economicobjectives while remaining within ecosystem-level conservation limits.Communication9. Plans should be developed at an early stage on how the information from indicators can best becommunicated to scientists, policy and decision makers, and the general public. The plans shouldinclude publishing concise, attractive executive summaries of major ecosystem status reports that willdescribe important trends and patterns in marine ecosystems for non-scientists.10. To reach policy makers and the public in Asian countries, future iterations of the Synthesis chapter inthe PICES North Pacific Ecosystem Status report should be published in multiple languages.11. The development by the National Marine Fisheries Service of an Ecosystem Considerations websitegreatly increased access to time series of ecosystem indicators for the Alaska region, and should bemaintained and enhanced.12. An overview of the status of the Bering Sea ecosystem(s) should be presented at the annual MarineScience in Alaska Symposium to foster broader communication among the diversity of regionalscientists, managers and the public.Specific recommendations from individuals/groups can be found under Discussion Group Results in thisreport.
