Abstract

Schaefer model is extensively used for efficient fishery management.
Generally, due to mathematical convenience, the assumption is made that the
fish population is in equilibrium. In this paper, the procedure for fitting a
nonequilibrium Schaefer model is described. Comparative performance of the
equilibrium vis-a-vis nonequilibrium version is carried out on catch and effort
data of Bombay duck (Maharashtra) during 1974-'84. As the results obtained
by the two approaches are found to differ markedly, it is concluded that
nonequilibrium approach should invariably be adopted in order to capture
reality.
