Abstract
Larval cottids were found in stomach contents of juvenile sockeye salmon (Oncorhynchus nerka) caught in open-water areas of Brooks Lake on the Alaska Peninsula. Although freshwater cottids are usually benthic fishes, this suggested that the larvae might be planktonic. Subsequent capture of Cottus aleuticus larvae 8 to 13 mm in total length taken at midlake over deep water confirmed that larvae of this species are at times planktonic. The larvae were caught in a conical net towed near the lake surface. Other accounts of juvenile sockeye salmon eating cottid larvae and the more common situation, that of cottids eating salmon eggs, alevins, and fry, are also reviewed.This publication has 1 reference indexed in Scilit:
