Proximate Composition and Fatty Acid Signatures of Selected Forage Fish Speciesin Prince William Sound, Alaska. EXXON VALDEZ Oil Spill Restoration Project 95121

摘要

The proximate composition and fatty acid signatures of several prey species,which are important for sea birds and marine mammals in Prince William Sound, Alaska, were determined. Fish were collected as part of the SEA cruises in the fall of 1995 and were frozen immediately and then shipped to Galveston for analysis. Fatty acid signatures of herring, pollock, and tomcod were consistent with previously reported data, Three different species of sole (English, rock, and flathead) were also consistent with previously reported data for yellowfin sole. Detailed analyses of individual rock fish suggest that this species may exhibit trends in some specific fatty acids (20:5 n-3, 22:6 n-3) which differ from herring or pollock.
