akuugun, a new species of eelpout (Perciformes: Zoarcidae) from the Aleutian Islands.
In addition to qualitative observation of all 47 species, quantitative estimates of %Hb polymerized RBCs were conducted for 7 species found to exhibit Hb polymerization: Boreogadus saida (Lepechin, 1774); Lycodes
reticulatus Reinhardt, 1835; Gadus morhua Linnaeus, 1758; Urophycis chuss (Walbaum, 1792); Merluccius bilinearis (Mitchill, 1814); Pollachius pollachius (Linnaeus, 1758); and Notacanthus chemnitzii Bloch, 1788.
In addition to the species listed in Table 1, Johansen mentioned, in an unpublished manuscript, nine other species: broad whitefish (Coregonus nasus), sardine cisco (Coregonus sardinella), saffron cod (Eleginus gracilis), fourline snakeblenny (Eumesogrammus praecisus), fish doctor (Gymnelus viridis), polar eelpout (Lycodes
turneri), hamecon (Artediellus scaber), Artedius sp.
The otoliths from two Canadian eelpout, Lycodes
polaris, were also measureable, but because no size or weight conversions have been developed for this species, fish size could not be estimated (Table 5).
Other common species included Blackbelly Eelpout (Lycodes
pacificus) and Pacific Tomcod (Microgadus proximus).
Species that were captured only by seine were Arctic cisco and threespine stickleback (Gasterasteus aculeatus), whereas species captured only by trawl were longhead dab (Limanda proboscidea), rainbow smelt (Osmerus mordax), whitespotted green ling (Hexagrammos stelleri), and marbled eelpout (Lycodes

Furthermore, species that were associated with both 80 and 160 m included large spiny dogfish, and quillback rockfish (Sebastes maliger), brown rockfish (Sebastes auriculatus), blackbelly eelpout (Lycodes
pacificus), Pacific tomcod (Microgadus proximus), walleye pollock (Theragra chalcogramma), shiner perch (Cymatogaster aggregate), pile perch (Rhacochilus vacca), black tip poacher (Xeneretmus latifrons), slender sole (Lyopsetta exilis), and plainfin midshipman (Porichthys notatus; Fig.
Some eelpouts (Lycodes
spp.), sculpins (Cottunculus spp.) and other snailfish species (Paraliparis bathybius, Rhodichthys regina, and Careproctus spp.) were also taken, but in very low abundance.
cortezianus (Gilbert 1890)--Bigfin Eelpout (Fig.
crameri), because this is an important commercial species; kelp greenling (Hexagrammos decagrammus); and bigfin eelpout (Lycodes
cortezianus), because the day-night activity patterns of the latter two have been studied in shallow temperate areas (Moulton, 1977).
