Abstract
A method is proposed for solving the natural mortality rates, MA and MB, for two stock components with different von Bertalanffy growth rates (KA and KB), where total mortality rates ZA and ZB are available for a series of years, and where the assumption of a constant M/K ratio can reasonably be made. The method has obvious applications for populations where the two sexes have different growth and mortality schedules, but have a constant relative availability to fishing.Keywords
