The ability of homing sockeye salmon (Oncorhynchus nerka) to discriminate between two populations of their own species on the basis of odours was tested in a Y-maze choice apparatus and by electrophysiological recordings from the olfactory rosette. The tests were performed with adult sockeye captured at the entrances to Great Central Lake and Sproat Lake on Vancouver Island, British Columbia, Canada. In behaviour experiments, Great Central Lake sockeye salmon were significantly attracted to…

Factors affecting the recognition of population-specific odours by juvenile coho salmon
Juvenile coho salmon Oncorhynchus kisutch from the Quinsam, Big Qualicum and Puntledge Rivers, British Columbia, Canada, discriminated between the chemical emanations of similarly aged salmon from
Homing and spawning site selection by sockeye salmon (Oncorhynchus nerka) in Iliamna Lake, Alaska
This work investigated the importance of homing, attraction to spawning site characteristics, and attraction to conspecifics in similar reproductive condition as factors influencing spawning site selection in sockeye salmon in Iliamna Lake, Alaska.
Homing experiments with parr, smolt and residents of anadromous Arctic char Salvelinus alpinus and brown trout Salmo trutta: transplantation between neighbouring river systems
Olfaction is decisive for the homeward migration of anadromous salmonids and two different olfactory hypotheses for explaining how this mechanism works have been proposed, but they differ with regard to the origin of the odours that define home.

Neurophysiological studies revealed crucial roles of olfactory functions on imprinting and homing during downstream and upstream migration, respectively, in anadromous and lacustrine salmonids.
Physiological Mechanisms of Homing Ability in Sockeye Salmon: From Behavior to Molecules Using a Lacustrine Model
Results demonstrate the suitability of the lacustrine model for studying the physiological mechanisms of homing ability in sockeye salmon.
Straying of adult sockeye salmon, Oncorhynchus nerka, entering a non-natal hatchery
Mature salmonids respond to the stimulus of imprinted odors with positive rheotaxis and move downstream when they no longer detect home odors, and movement up a non-natal stream does not necessarily mean that the fish will spawn there.
Attraction of migrating adult sockeye salmon to conspecifics in the absence of natal chemical cues
The results indicate that sockeye salmon are attracted to conspecifics when imprinted natal cues are absent, but not when they are present, which suggests that pheromones may provide a directional cue that is secondary to the primary cue of imprinted chemicals.
Mechanisms of homing in salmonids
It is shown that the rates of homing (and straying) vary among species and among populations of the same species, depending on their biological and ecological features, on a variety of environmental factors and conditions, and anthropogenic impact.
Effects of natal water concentration and temperature on the behaviour of up-river migrating sockeye salmon
There were few associations between metabolic stress indices and reproductive hormone levels with this behaviour in either population; however, higher temperatures and elevated natal water concentrations in the Seton River were associated with shorter powerhouse delays and less wandering in late-run migrants.
Discrimination of family-specific odours by juvenile coho salmon: roles of learning and odour concentration*
Although juvenile coho salmon learn, remember, and are subsequently attracted by sib-specific odours in early life, familiar odours are not always preferred over unfamiliar conspecific odours.


Olfactory Perception in Migrating Salmon: III. Stimulants for Adult Sockeye Salmon (Oncorhynchus nerka) in Home Stream Waters
Adult sockeye salmon (Oncorhynchus nerka) captured during their spawning migration to Great Central Lake, British Columbia, show a consistent response in the laboratory to water taken from the outlet
Pheromones and the water source preferences of adult coho salmon Oncorhynchus kisutch Walbaum
Adult coho salmon, Oncorhynchus kisutch, were tested in a two-choice apparatus with a variety of water sources and preferred home water without coho odours over an unfamiliar water source.
The use of chemical cues in the upstream migration of coho salmon, Oncorhynchus kisutch Walbaum
It is revealed that chemical cues are used by the salmon in their upstream migration and differential responses to current appear to serve in segregating fish imprinted to odours of different home streams.
Responses of Returning Adult Coho Salmon to Home Water and Population‐Specific Odors
Evaluated 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, the adult salmon preferred home water, lending support to the hypothesis that environmental odors are the primary stimulus attracting homing salmon.
A pheromone hypothesis for homeward migration in anadromous salmonids
The seasonal migration schedules in the anadromous salmonids of the Salangen river system, North Norway are presented and a pheromone hypothesis is proposed for the entire homeward navigation in an adromous Salmonids.
Does the Route of Seaward Migration of Fraser River Sockeye Salmon (Oncorhynchus Nerka) Smolts Determine the Route of Return Migration of the Adults
Sockeye salmon (Oncorhynchus nerka) can choose a northern or a southern route around Vancouver Island during their homing migration to the Fraser River. The percentage of fish taking the northern
Behavioral Stock-Isolating Mechanisms in Great Lakes Fishes with Special Reference to Homing and Site Imprinting
Research on salmonids has provided the best evidence for site imprinting and natal homing in fish and Tagging and transplantation experiments with these species have been especially important sources of information.
