Seasonal and spatial variation in the biomass and size frequency distribution of fish associated with oil and gas platforms in the northern Gulf of Mexico

Abstract

Hydroacoustic and visual surveys were made on the fish assemblages of three platforms off Louisiana. From the Abstract: “Six species made up more than 90% of the fishes observed at each site on any survey and platform assemblages culd be characterized as not specious and dominated by a few species at reach structure…While the species assemblages found at each site were unique, the dominant species at each site was different and some overlap of observed species existed between sites. Season migrations were common at each of the study sites…”
