摘要：
Chemoattraction of fry of Arctic charr [Salvelinus alpinus (L.)] to water scented by conspecifics of the same age was studied in a Y-maze fluviarium. The fry were offspring of two sympatric populations. Specimens of one of the two populations were indifferent to conspecific odor during the two-month experimental period. Specimens of the other population showed significant attraction to water scented by either population when their mean fresh weight was higher than 0.09 g. A significant difference in rheotactic response also was observed. Offspring of the population spawning in an inlet stream showed less motivation for upstream swimming, although they were significantly attracted to conspecific odor. © 1990 Plenum Publishing Corporation.
