Modeling the Relationship between Biomass and Revenue in a Regional Setting with an Example from the Brown Shrimp Fishery in North Carolina

摘要

Two models emerge in the paper: one relates revenue to catch biomass, and the other relates the weight of captured fish to fishing net mesh size and the character of the fish population. Each incorporates the influences of both structural and random variation. In turn these are used to describe how a particular mesh size (as characterized by a mesh selectivity curve) affects the catch biomass, catch revenue, and catch profit.
