Individual Measurements from trawl surveys of fish and invertebrates in Coastal Alabama, Mississippi, and the Chandeleur Islands, January - November, 2017

Abstract

Fishes and macroinvertebrates were collected using a 12.8m semi-balloon otter trawl with 4 cm mesh in Spring and Fall of 2017 in the coastal waters of Alabama and Mississippi, as well as the Chandeleur Islands. Length measurements and individual biomass of a subset of fish and macroinvertebrates taken in the trawls were recorded for each trawl. Length measurements appropriate for each species were recorded to the nearest millimeter, and biomass was recorded to the gram.

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.
