A mathematical model of biological resource dynamics, using Caspian / Ural sturgeon as a case study

Abstract

Some of the general principles involved in constructing mathematical models of biological resource dynamics are presented along with some of the requirements of such models for them to have value in terms of management application. A case study of sturgeon population dynamics in the Caspian Basin, using physical and biological parameters, is used to show theoretically how such a model can be developed and applied. The results of the case study are presented in graphic form, and the influence of different pro-cesses on the outcome of the calculation is discussed.
