To determine whether genetic variation underlies variation in development rate of pink salmon, the authors analyzed variation in embryo development rate in the laboratory. The authors found that duration of development is no longer for a late returning fish than for an early returning fish; thus development rates in the two runs have adapted to different temperatures. Evidence of genetic variation, and of interactions between genotypes and environments, are important for resource conservation because harvest management and hatchery practice have potential to reduce genetic variation in salmon populations.
