Abstract
The yield of striped bass (Morone saxatilis) in biomass and numbers was estimated for constant recruitment of young fish into the population on the basis of vital statistics of the Maryland stock. Separate computations were performed for males, females, and sexes combined. Yield in biomass per individual entering the population was highest when the minimum legal length was in the range of 80‐90 cm fork length and no upper size limits were imposed. The yield would increase at these size limits in both the Bay and Coastal fisheries, although the Coastal fishery would gain a slight relative advantage because the escapement of immature females from the Bay would increase. The most significant negative effect associated with an increase in the size limits would be the elimination of the traditional fisheries that focus on panfish (male and immature female striped bass 28‐40 cm long). Although the length limits recommended in an existing Interstate Fisheries Management Plan for Striped Bass will increase yield per recruit, more stringent regulations would further increase the yield.This publication has 0 references indexed in Scilit:
