The eastern Bering Sea has experienced rapid and intensive development of commercial trawl fisheries. Because of good record keeping and the relatively brief history of fishing it is possible to reconstruct the spatial and temporal patterns of exploitation. Previously unfished (UF) areas can be identified and directly compared with heavily fished (HF) areas to investigate long-term consequences for the benthos. Using this approach, macrofauna populations in a shallow (48 m average) soft-bottom area were studied during 1996. Catch data were extracted from the AFSC NORPAC database for years 1973-2001 to provide a summary of trawl catch effort, specific focus was placed on the area within Fisheries Management Area 512. The total number of hauls and tonnage for each data point are provided. Foreign, domestic, and Joint Venture fishing vessels are also described.

Obsolete - AFSC/RACE/EcoFOCI - Trawl catch data collected in support of FOCI assessment surveys and ecosystem observations in the Bering Sea and the Gulf of Alaska 1993 to Present
공공데이터포털
The trawl database contains multiple tables of data. The ‘haul’ table contains the location, date, time and depth of the trawl haul. The ‘catch’ table contains the numbers and weights of the taxa in each haul. The ‘length’ table contains the lengths of selected taxa in each haul. There is data for the eastern Bering Sea for 2008, 2010, 2012, and 2014. There is Gulf of Alaska trawl data from 1993 to 2015.

AFSC/RACE/GAP/Rooper: ME70 mapping of trawlable grounds in the Gulf of Alaska
공공데이터포털
The core function of the Resource Assessment and Conservation Engineering (RACE) Division is to conduct quantitative fishery surveys and related ecological and oceanographic research to measure and describe the distribution and abundance of commercially important fish and crab stocks in the eastern Bering Sea, Aleutian Islands, and Gulf of Alaska. This includes measuring the abundance of fish (including rockfishes) in rocky untrawlable areas. To accomplish this, we are mapping untrawlable areas using an ME70 multibeam data. These data area stored as image files ArcGIS shapefiles
