Mating success of alternative maturation phenotypes in male Atlantic salmon, Salmo salar

  title={Mating success of alternative maturation phenotypes in male Atlantic salmon, Salmo salar},
  author={Jeffrey A Hutchings and Ransom A. Myers},
Mature male parr successfully fertilized eggs of anadromous female Atlantic salmon, Salmo salar, in competition with anadromous males under simulated natural conditions. Mating situations were created in which mature male parr and anadromous males competing for the opportunity to spawn with an anadromous female differed in allelic forms of the same enzyme. Females deposited eggs into a sequence of 3 or 4 eggs nests. The mean proportion of eggs in a redd fertilized by parr increased with… CONTINUE READING
