Comparing diet composition from prey remains and fecal samples
DRAFT Document – all unpublished results should be considered preliminary. Please do not cite without permission of the authors. Panel Requests: Comparison of diets determined from fecal samples and prey remains (scales and tissue). Data from Puget Sound were presented by NMFS at the workshop; this...
