Government agencies are usually interested in estimating the annual exploit
ation 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 c
reel survey (which is a type of angler survey). We consider moment estimati
on of the exploitation rate. We also consider estimation of the exploitatio
n rate by stratifying the space-time units of the fisheries.
