Biomass Dynamic Models

Abstract

Biomass dynamic models are the simplest stock assessment models that are commonly used. Stock-recruitment models are in most cases used only as a part of a complete age-structured assessment. Only for semelparous species, and in practice only for Pacific salmon, can stock-recruitment models be used by themselves to evaluate alternative fishing plans. We presented stock-recruitment before biomass dynamics as a more logical introduction to the problem of parameter estimation, since most stock-recruitment models involve fitting only two parameters, whereas most biomass dynamic models involve fitting at least three parameters
