Abstract

This paper considers the applicability of the Schaefer model and the Fox model to the tuna fishing industry of the Maldives. Examination of Maldivian catch and effort data throws doubt upon the applicability of these models to this fishing industry, which depends on a highly migratory species. An alternative production-type model based on a population threshold assumption is suggested and found to be much more consistent with Maldivian effort and catch data. Such a model may also have application to some other fisheries based on migratory species.
