Reproductive frequency (?) | Semelparous References (not structured): Morrow JE (1980) The freshwater fishes of Alaska. University of. B.C. Animal Resources Ecology Library. 248p Comments: Females may spawn with more than one male and may build more than one nest over the course of the season. Both sexes die shortly after spawning. |
Reproductive type (?) | Sexual References: Morrow JE (1980) The freshwater fishes of Alaska. University of. B.C. Animal Resources Ecology Library. 248p Comments: Eggs are laid in a redd, a long trough in the gravel that the females creates by lying on her side and beating her tail. When spawning is complete, the eggs are covered with gravel and the female guards the nest as long she has the energy to do so. Females may spawn with more than one male and may build more than one nest over the course of the season. Both sexes die shortly after spawning. |
Developmental trait (?) | Spawning References: Kottelat M, Freyhof J (2007) Handbook of European freshwater fishes. Publications Kottelat, Cornol, Switzerland. 646p Comments: When pink salmon reach adulthood, they move from marine habitats into freshwater rivers to breed, although some populations remain in fresh water year-round. Migration occurs from July through September; spawning occurs from mid-July until late October. Spawns in riffles or at head of riffles in shallow water with current up to 1.5 m/s, and clean coarse gravel. |
Characteristic feeding method / Life stage (?) |
References (not structured): Morrow JE (1980) The freshwater fishes of Alaska. University of. B.C. Animal Resources Ecology Library. 248p Comments: Fry may feed on nymphal and larval insects while in fresh water, but may not feed at all. In the sea, young feed on copepods and larvacean tunicates, its diet shifting to amphipods, euphausiids and fishes as the fish grows |
