Fish culture data - Development and optimization of grow out diets for sablefish (Anoplopoma fimbria)
공공데이터포털
Our experience with juvenile sablefish and long term rearing of broodstock indicate that salmon grower feeds currently used by commercial sablefish farmers for grow out are not optimally formulated to support maximum growth and efficient feed conversion. However, there are no published studies examining the effects of dietary nutrient balance on productive performance and growth at any post larval life-history stage for this species, and there are currently no commercial diets specifically formulated for sablefish in the marketplace. Because of the large impact of feed cost on the economic viability of farming sablefish, we are focusing on grow out diets intended for use during the post larval stages of development when the fish are being reared to harvest size. In this research, we use a novel statistical mixture model and response surface analysis method to determine the optimal level of dietary protein, lipid and digestible carbohydrate for testing. This approach permits simultaneous testing of diet formulations encompassing the full range of protein, lipid and digestible carbohydrate that can be produced commercially using todayâs most advanced extrusion feed manufacturing technology. Raw data on rearing densities, tanks, water temperature, mortalities, ration and feed size may be available.
Physiology Data - Developing diets and feeding strategies for improved growth and performance of juvenile and adult sablefish
공공데이터포털
Feed costs and time to harvest are key factors affecting the economic viability of domestic sablefish (Anoplopoma fimbria) aquaculture. Use of fast growing all-female monosex stocks dramatically reduces time to harvest, but our research to date indicates that the commercial salmon feeds typically used by industry are not optimally formulated for sablefish and there is still a high degree of potential for improved growth and feed conversion. The effects of dietary balance of protein, fat, and carbohydrate on productive performance, growth and feed conversion at any post-juvenile stage of development are unknown, and there are no commercial diets specifically formulated for sablefish aquaculture in the marketplace. Dietary nutrient imbalances combined with inappropriate feeding schedules and strategies contribute to poor nutrient utilization and are unlikely to fully support the growth potential of this species, impeding continued efforts to improve performance during grow-out to harvest. Thus, research activity focuses on establishing performance optimized diets and feeding strategies that support maximum growth, efficient feed conversion and other economically important traits such as fillet yield. Informaion on tissues collected and physiological measures (e.g., plasma steroid levels) may be available.

Hook and Line Survey
공공데이터포털
The Hook and Line Survey will collect species-specific aggregate weight and abundance, as well as individual lengths and biological characteristics (e.g., age, maturity, genetics, diet, energetics). Tagging will also be conducted opportunistically and by request. In addition to deploying hook and line gear, the survey will deploy a benthic stereo camera system to collect additional information on fish density, abundance, and demographics. A suite of environmental data will be collected via conductivity, temperature, and depth (CTD) deployments at each survey station. Habitat data will be collected using seafloor imaging (still or video) techniques. Finally, operational and gear deployment data will be collected for every gear set. The Hook and Line Survey is a new survey, so all data uses are prospective. Once the survey is mature, the data will be used in stock assessments for a variety of commercially and recreationally important species and for analyses that support management actions. This will encompass species covered by the Mid-Atlantic Fishery Management Council (MAFMC), New England Fishery Management Council (NEFMC), and Atlantic States Marine Fisheries Commission (ASMFC), including but not limited to Atlantic cod (Gadus morhua), haddock (Melanogrammus aeglefinus), pollock (Pollachius pollachius), white hake (Urophycis tenuis), red hake (Urophycis chuss), summer flounder (Paralichthys dentatus), scup (Stenotomus chrysops), black sea bass (Centropristis striata), bluefish (Pomatomus saltatrix), spiny dogfish (Pomatomus saltatrix), Atlantic croaker (Micropogonias undulatus), and skates. At least 5 years of Hook and Line Survey data will be required before abundance indices from the survey are integrated into stock assessments, but habitat and biological data could be used immediately to supplement existing data streams. Beyond stock assessments and management, the data from the Hook and Line Survey will also be used in research to understand the cumulative impacts of offshore wind on resource species and their habitats. Note that the Hook and Line Survey is a new survey and is still in planning and review. The exact geographic extent and survey strata are still under review. The geographic extent displayed here is tentative.

Enhanced Biological Sampling Data
공공데이터포털
This is a database of a variety of biological, reproductive, and energetic data collected from fish on the continental shelf in the northwest Atlantic Ocean. Species sampled in this database thus far include winter flounder, yellowtail flounder, summer flounder, haddock, cusk, Atlantic wolffish, and Atlantic herring. Data are collected from fish provided principally from fishermen participating in the NECRP Study Fleet. Some fish are taken from other NECRP research studies, and a small number from NEFSC surveys and surveys by MADMF and URI GSO. The catch location data is provided in views from the relevant FVTR, SVDBS, or other tables for a few cooperative research or external programs. The biological data includes general physical data (weights, lengths, organ weights, macroscopic maturity stage), age data, and other reproductive data. Measures collected from preserved gonad samples includes data for estimation of fish fecundity (oocyte counts and diameters) and from grading gonad histology for determination of maturity and seasonal reproductive status. In addition, relative measures of energetic condition are collected (including tissue wet weight and dry weights and bioimpedance data), and for some fish food habits data were collected in the first 18 months of data collection.
