Appendix A Mean seasonal whole-body energy content and proximate composition (+sd) of forage species in southeastern Alaska. Values for herring are averaged over a 3 year collection period, eulachon, capelin, hake and pollock are averaged over 2 years and the remaining species are averages primarily from a single year
