Injured Resources Addressed: Pacific Herring

Abstract: This project will begin the systematic development of fatty acid profiles and lipid class analysis to identify diet differences and quality in forage fish and their prey. The spatial and temporal variability of fatty acid profiles in herring, sand lance, and zooplankton will be examined and related to the nutritional condition of these forage fish. The spatial comparisons, which began in FY 98, will provide insight into the energetic differences in forage fish in disparate parts of Prince William Sound. These comparisons are based on samples collected by APEX (Project /163). In FY 99, temporal comparisons will be made, which will provide information on the energetic changes that inevitably occur with seasonal, ontogenetic, and reproductive changes.
