Appendix A Percent prey specific relative importance (%PSIRI) for prey items in each data grouping. Included are calculations for the trophic level (TrL), Shannon-Wiener Diversity Index (H’) and evenness (E). The prey categories are as follows: AMPHI = ‘amphipod’; BIVALVE = all clam, mussels, all other bivalves; CEPH = ‘cephalopods’, all squid and octopus; CRAB = all species of crabs, including any commercial species; COMM FISH = includes Pacific salmon (Oncorhynchus spp.), cod (Family Gadidae), rockfish (Sebastes spp.), pollock (Gadus chalcogrammus), and flatfish (Family Pleuronectidae); FORAGE FISH= ‘forage fish’, includes Pacific herring Clupea pallasii, capelin Mallotus villosus, eulachon Thaleichthys pacificus, Pacific sandlance Ammodytes hexapterus, and other smelts (Family Osmeridae); INVERT = ‘other invertebrates’; JELLY/SALP = ‘jellyfish/salps’, includes any comb jellies, salps or other jellyfish parts identified; OTHER FISH= ‘other fish’, consists mostly of sculpins (Family Cottidae), greenling (Family Hexagrammidae), and myctophids (Family Myctophidae); SHRIMP = all species of shrimp, euphausiids and mysids; WORMS = any marine worms. The data groupings are: location (Cook Inlet = CI, Prince William Sound = PWS, Yakutat Bay = YAK, and Gulf of Alaska = GOA, Fig. 1), gear type (longline = LL, setnet = SET, sport = SPT, and bottom trawl = TWL), year (2004, 2005, and 2006), season (spring = SPR, summer = SUM, and autumn = AUT) depth (0 – 99 m = DEP0, 100 – 199 m = DEP100, 200 – 299 m = DEP200, and > 300 m = DEP300), sex (male = M and female = F), length (< 80 cm TLext = TL70, 80 – 89 cm TLext = TL80, 90 – 99 cm TLext = TL90, and > 100 cm TLext = TL100) and weight (< 2 kg = WT0, 2 - 3.9 kg = WT2, and > 4 kg = WT4)
