7. Problems in estimating population length at age from commercial catches, the Patagonian toothfish as an example

   Abstract:  Age based fishery population models require information on size at age of the fished ... population and the commercial catch. Age-length keys can be produced by standardised random sampling ... of the commercial catches. This information does not necessarily reflect the size at age of the fished population ... , a method is developed to estimate size at age of the population using information collected from ...
