Fishery-independent Bottom Trawl Surveys for Deep-water Fishes and Invertebrates of the U.S. Gulf of Mexico, 2002–08

摘要

From 2002 through 2008, the Mississippi Laboratories of the NMFS Southeast Fisheries Science Center, NOAA, conducted fishery-independent bottom trawl surveys for continental shelf and outer-continental shelf deep-water fishes and invertebrates of the U.S. Gulf of Mexico (50–500 m bottom depths). Five-hundred and ninety species were captured at 797 bottom trawl locations. Standardized survey gear andudrandomly selected survey sites have facilitateduddevelopment of a fishery-independent time series that characterizes species diversity, distributions, and catch per unit effort. The fishery-independent surveys provideudsynoptic descriptions of deep-water fauna potentially impacted by various anthropogenic factors.
