| Summary: | No abstracts are to be cited without prior reference to the author.The most common methods used in stock assessment are VPA and the statistical catch-at-age methods, which permit the reconstruction of the numbers-at-age of exploited stocks and provide estimates of mortality rates for management advice. The difference between these models is the statistical assumptions allowing the fitting of parameters by considering how errors enter into these models and using several data sources for the estimation procedure. Fishery managers are increasingly asked to consider multispecies interactions in their decisions because there is an increasing tendency to recognize that fish populations are not isolated. One option to achieve this goal is the MSVPA that incorporates predation into the virtual population; however, it lacks statistical assumptions. In this work we use a two-species system to incorporate the predation equations from MSVPA into a multispecies statistical catch-at-age model (MSM). Results suggested ... |
