Abstract
Two‐year‐old hatchery‐reared progeny of inlet‐ and outlet spawning brown trout from Lake Tytifjorden were released at the mouth of the R. Imsa, south‐western Norway. There were significant differences in migratory direction of juveniles between the two populations. After release, juvenile fish from the outlet river population moved against the current and ascended the R Imsa, while the inlet rivet fish tended to migrate with the water current to the sea. This differential response to water current in juveniles appears to be due to genetic differences between the populations, and parallels that found in their ancestors native environments.
