Larval Tuna Data collected between 1950 and 1964 in the eastern and central Pacific Ocean
공공데이터포털
Larval tuna data were collected on NOAA research vessels or charter vessels between 1950 and 1959 and between 1961 and 1964. 1955 - 1959 IATTC data were provided to Honolulu Laboratory, and PIFSC received IATTC's approval to share their data with the public. The dataset includes date, position, depth of tow, type of gear, volume of water strained, surface temperature, surface salinity and counts of tuna larvae.

공공데이터포털
Sardine Age-Length Data was collected between 1941 and 1964 from port samplings along the western coast of Canada, Mexico and the United States. The date the sample was obtained, port, year class, sex, number of rings counted, fish length(s) for the age(s) of the fish determined by the number of rings counted and the fish length at capture are found in the database.
Annual General Canvass Statistics
공공데이터포털
This data set contains annual quantities and value for all seafood products that are landed and sold by established seafood dealers and brokers in the Southeast Region (North Carolina through Texas). These types of data, referred to as the general canvass landings statistics, have been collected by the NOAA Fisheries Service, National Marine Fisheries Service and its predecessor agency, the Bureau of Commercial Fisheries. The data are available on computer since the early 1960's. The quantities and values that are reported in this data set include the annual landings that were initiated in 1962. Beginning in 1976, the data were collected monthly. See the sections on Links for the reference to the monthly general canvass landings. The annual general canvass landings include quantities and value for all living marine species and are identified by species (usually the local or common name). These data were collected by field agents employed by the National Marine Fisheries Service or the Bureau of Commercial Fisheries and assigned to local fishing ports. The agents contacted the majority of the seafood dealers or brokers in their assigned areas and recorded the quantities and value for each species or species category from the sales receipts maintained by the seafood dealers. In addition, information on the gear and area of capture is available for most of the landings statistics in the data set. Based on their knowledge of the fishing activity in the area, the agents would estimate the type of fishing gear and area where the fishing was likely to have occurred. More detailed information on the caveats associated with these data is provided in the Characteristics, Caveats and Issues section. However, because these data are summaries, they do not contain information on the quantities of fishing effort or identifications of the fishermen or vessels that caught the fish or shellfish.
ROUNDSCALE SPEARFISH general morphometric data
공공데이터포털
Little information has been produced since the mid 1970s about the roundscale spearfish Tetrapturus georgii (Lowe, 1840). The most complete species description was based on examination of four individuals from the eastern Atlantic. On the basis of detailed laboratory examination of 16 specimens, as well as fishery observer information and biological samples from an additional 49 individual specimens, we update morphological descriptions and key identification characteristics of this species for the western North Atlantic. Key characters include lateral scale morphology and position of the anal opening the scales having rounded and broad anterior bases with usually multiple posterior points, and the anal opening located a distance between 0.48 and 0.81 the height of the first anal fin.
FL BAY SPECTROUT-POPULATION STATUS
공공데이터포털
Juvenile spotted seatrout and other sportfish are being monitored annually over a 6-mo period in Florida Bay to assess their abundance over time relative to restoration of a more natural pattern of freshwater flow from the Florida Everglades through implementation of the Comprehensive Everglades Restoration Plan (CERP). This monitoring and assessment project will provide a scientific basis for the selection of spatial and temporal abundance indices, performance measures, and targets to determine the effect of CERP on Florida Bay resources. Monitoring annually during the period of greatest abundance, May through October, will provide data to determine whether there is a significant relationship of sport fish distribution and abundance to salinity and other environmental variables. Habitat suitability models will be developed from the data and will be used to predict distribution and abundance under different scenarios of freshwater inflow, past and future.
Washington coast sablefish - Reproductive Life History Analysis of Sablefish Populations off the Washington and California Coasts
공공데이터포털
Sablefish (Anoplopoma fimbria) have a wide distribution along the Pacific coast, extending from Baja California to Alaska, the Bering Sea and through to the eastern coast of Japan. A unique feature of these fish is the wide variation in temperature and depth that sablefish experience throughout their life cycle, extending from depths 200m as adults to the surface as larvae and juveniles. While the landed weight of sablefish in the commercial fishery is relatively small, the exceptionally high value of this species ranks it 3rd in economic value to walleye pollock and Pacific cod. As such, sablefish are highly managed throughout the Pacific, and understanding the biology of this species is essential for proper management. The aim of this project is to characterize the reproductive life history of two populations of sablefish in coastal Washington and California. Fish will be collected from the same geographical location on a monthly basis for one year. The reproductive status will be determined from gonadal histology and plasma sex steroid levels, and age will be determined from otoliths. It is expected that data on size, age, rate of gonadal development, seasonal timing of spawning, fecundity, frequency of reproduction, and potential shifts in distribution of sexes will be obtained. This study applies directly to the Magnuson-Stevens Fishery Conservation and Management Reauthorization Act, because the data will be used to improve stock assessments and estimates of spawning biomass in this commercially important species. This project is a cooperation with the commercial fishing industry and scientists at the Northwest Fisheries Science Center (NWFSC) and Southwest Fisheries Science Center (SWFSC).

AFSC/REFM: Alaska groundfish AGEDATA database,1982 to present
공공데이터포털
The AFSC AGEDATA database is a collection of historic and ongoing fish ageing efforts by the Alaska Fisheries Science Center's Age and Growth Program from 1982 to present. The database contains over 900,000 observations of biological and collection data from survey and observer fish specimen collections spanning from 1976 to 2015. Primarily the species aged are comprised of commercially important species of Alaska and the west coast such as walleye pollock, Pacific cod, rockfish, sablefish, and flatfish, although smaller numbers of other species are included as well such as skates, sculpins, and forage fish species. Specimen data includes fish age estimates, fish length, sex, weight, collection coordinates, date of collection, fish ageing methodologies, age reader information, and ageing structure descriptions.
