All species were identified to the lowest possible taxonomic level and counted. A wet weight estimate of total biomass (+ grams) was attained for each species using portable spring scales. Finfish collected in 2010 were measured for length (standard, fork, and/or total as appropriate). Purpose: The trawls were part of a larger project that also included longline surveys to compare fish community structure in coastal Alabama and Mississippi before and after the Deepwater Horizon oil spill on April 20, 2010.
