Estimation of exploitation rate by combining mark-recapture procedures with a creel survey

Government agencies are usually interested in estimating the annual exploitation rate of a fish population for recreational and commercial fisheries. In this paper, we propose a model-based approach for the estimation of the exploitation rate. Our approach combines mark-recapture procedures with a creel survey (which is a type of angler survey). We consider moment estimation of the exploitation rate. We also consider estimation of the exploitation rate by stratifying the space-time units of the fisheries.
