Larval liparids were relatively abundant and widespread in 1990; however, most of the liparid catch (291 fish) was obtained at one station in the east sector during the late period.

Arctic cod, capelin, and liparids were the most abundant marine fishes in the catches, while arctic cisco was the only abundant diadromous freshwater species.
Liparids were assumed to be age-0 on the basis of their occurrence in the plankton and their size (see Able et al., 1986).
Capelin were most aggregated (smallest k), followed by arctic cod, liparids, and arctic cisco.
Age-0 liparids were significantly larger in 1990 than in either 1988 or 1991 (Kruskal-Wallis test: H = 12.06, df = 2, p < 0.001); multiple comparisons tests: Q = 14 and 9.95, Qc
Arctic cod, age-0 capelin, liparids showed an apparent affinity for comparatively cool (> 1 - 3[degrees]C), moderately saline (> 15 - 20 psu) waters.
Age-0 liparids also were well represented in the 1988 tow net catch, while the seine captured none.
Liparids: Age-0 liparids, associated primarily with relatively saline marine water, are fairly abundant in the epipelagic fish community.
