A Physiologically-Structured Fish Population Model with Size-Dependent Foraging.

A Physiologically-Structured Fish Population Model with Size-Dependent Foraging. Math Biosci. 2019 Jul 22;:108233 Authors: Gwhila M, Willms AR Abstract A previous physiologically-structured model for a fish population based on individual-level characteristics is studied. The foraging rate is generalized to include a size-dependent functional response and the energy distribution of adults is generalized to permit both reproduction and growth. Equilibria are determined and their stability studied along with a discussion of harvesting strategies. The model with these generalizations is shown to give different predictions than the original model regarding age distribution of fish and harvesting strategies.
