Reproduction and Life Cycle of Sitka Fish

Mating Habits

The reproductive cycle of Sitka Fish is a remarkable process that involves distinct mating habits. Mature adult fish, driven by an internal instinct, navigate back to their natal streams and rivers to spawn. Female fish create nests, or redds, in the gravel beds by using their tails to dig depressions. Males compete for the opportunity to fertilize the eggs by engaging in elaborate displays of dominance and aggression. Once the female releases her eggs, the male fertilizes them externally with his milt.

Egg Laying and Hatching

After the female releases her eggs, they settle into the gravel nests while the male covers them with gravel to protect them from predators. The eggs incubate in the gravel for several weeks, with their development dependent on water temperature and oxygen levels. When the time is right, the eggs hatch, and tiny fry emerge and begin first feeding on their yolk sac before transitioning to feeding on small aquatic organisms. The survival rate during the egg and fry stages is critical for maintaining healthy populations.
