Can the length composition of krill in predator diets provide information on the age-dependence of krill natural mortality?
of krill is split between predator species. This method uses data on the length distribution of krill from ... predator stomachs. The proportions estimated depend, through the krill yield model, on the schedule ... of krill natural mortality at age. In principle, such a method would allow inferences about this schedule ... ., Butterworth, D.S. Title: Can the length composition of krill in predator diets provide information on the age ...
