Decapod crustaceans associated with the shrimp fishery of the central-south portion of Veracruz, Mexico

ABSTRACT The objective of this study was to analyze the brachyuran crab assemblages associated with shrimp fishing on the central-southern coast of Veracruz. Information was collected using 46 trawls organized within nine fishing quadrants. The total catch shrimp, bycatch, and discard were recorded...

Value index by species, species richness, diversity using Shannon and Weaver index, and equitability were determined.
