OLFACTORY PERCEPTION IN MIGRATING SALMON: II. STUDIES ON A LABORATORY BIO-ASSAY FOR HOMESTREAM WATER AND MAMMALIAN REPELLENT

Abstract
A laboratory bio-assay, based on the response of adult migrating sockeye salmon (Oncorhynchus nerka) to homestream water, is described. A characteristic response to the repellent in mammalian skin is discussed. The homestream substance(s) was tentatively identified as volatile, dialyzable, neutral, and heat-labile.The transportation and holding of sockeye in captivity was investigated.
