A method to improve size estimates of walleye pollock ( Theragra chalcogramma ) and Atka mackerel ( Pleurogrammus monopterygius ) consumed by pinnipeds: digestion correction factors applied to bones and otoliths recovered in scats.
The lengths of otoliths and other skeletal structures recovered from the seats of pinnipeds, such as Steller sea lions (Eumetopias jubatus), correlate with body size and can be used to estimate the length of prey consumed. Unfortunately, otoliths are often found in too few scats or are too digested...
