摘要

A generalized Bayesian population dynamics model wasuddeveloped for analysis of historical mark-recapture studies. The Bayesian approach builds upon existing maximumudlikelihood methods and is useful when substantial uncertainties exist in the data or little information isudavailable about auxiliary parameters such as tag loss and reporting rates. Movement rates are obtained throughudMarkov-chain Monte-Carlo (MCMC) simulation, which are suitable for use as input in subsequent stock assessmentudanalysis. The mark-recapture model was applied to English sole (Parophrys vetulus) off the west coast of the United States and Canada and migration rates were estimated to beud2% per month to the north and 4% per month to the south. These posterior parameter distributions and the Bayesian framework for comparing hypotheses can guide fishery scientists in structuring the spatial and temporal complexity of future analyses of this kind. This approach could be easily generalized for application to other species and more data-rich fishery analyses.
