Using mark-recapture and catch-age data to estimate fishing and natural mortality for the Patagonian toothfish at South Georgia
Abstract: This paper develops a Bayesian mark-recapture model for estimating both fishing ... between natural and fishing mortality. The model essentially follows tagged cohorts, with the estimated ... parameters being the fishing and natural mortality vectors for that particular cohort. The model was tested ... , while fishing mortality-at-age was estimated, only one value of the natural mortality was permitted ...
