摘要：

The reproductive success of mature male Atlantic salmon parr (Salmo salar) under natural spawning conditions was estimated using the polymorphism at the MEP‐2* locus as a genetic marker. The percentage of eggs per redd fertilized by parr varied considerably over the five redds examined (0·9–27.7%, mean 10·8%), but a gametic contribution from mature parr was detected in each case. Parr reproductive success has important implications for the population structure and evolution of the Atlantic salmon through its effect on gene flow. Copyright © 1992, Wiley Blackwell.
