Application of synthetic models for the assessment of Bombay duck, Harpodon nehereus (Ham.) stock off the Maharashtra coast

Abstract

For the formulation of a conceptual basis for future decision process and to evaluate the relation between catch and effort for the Bombay duck stock off the Maharashtra coast linear, exponential, hyperbolic and power formsare considered. The hyperbolic form fitted well to thedata indicating that the relation between catch and effort will be asymptotic within the normal range of effort. The significance of the asymptotic yield model is discussed in relation to dynamic pool model. The conclusions emerging from this study are that chances of biological and economical overfishing are rather remote for the Bombay duck stock off the Maharashtra coast.
