Aspects of the ecology and life history of the sculpin, Cottus aleuticus (Gilbert) were investigated. The fish exhibited a diurnal vertical migration towards the surface at night and towards the bottom during the day. It grew to a total length of 54 mm and attained this size at an age of about two years. The growth pattern was the same irrespective of season. It fed mainly on ostracods and chironomid larvae. Fecundity varied from 114–298 eggs.
