Can the length composition of krill in predator diets provide information on the age-dependence of krill natural mortality?
Abstract: A method is put forward which estimates the proportions by which the annual consumption ... 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 to be drawn by comparing the proportions which it predicts to independent estimates based on ...
