Responses of Returning Adult Coho Salmon to Home Water and Population-Specific Odors

Abstract
The olfactory stimulus guiding homing salmonids has been attributed both to environmental odors associated with the home stream and to pheromones from juveniles of the population. Evaluation of these two hypotheses was undertaken experimentally by giving adult coho salmon Oncorhynchus kisutch a choice between home water and nonhome water in which juvenile coho salmon of their population were held. Released in groups, the adult salmon preferred home water, lending support to the hypothesis that environmental odors are the primary stimulus attracting homing salmon.
