Trawl surveys of fish and invertebrates in Coastal Alabama, Mississippi, and the Chandeleur Islands, September to November, 2015

Abstract

Fishes and macroinvertebrates were collected using a 12.8m semi-balloon otter trawl with 4 cm mesh in Fall of 2015 in the coastal waters of Alabama and Mississippi, as well as the Chandeleur Islands. Abundance and biomass of all fish and macroinvertebrates taken in the trawls were enumerated by species and weighed to the nearest 0.1g or kg, depending on size. Length measurements appropriate for each species are included in dataset R4.x262.000:0005.

Purpose

Our purpose was to collect community-level data of the demersal fish and invertebrate species, looking for shifts in community composition due to remaining effects of oiling years after the oil spill.
