When do salmon swim downstream?
Salmon, a type of fish, swim downstream when they are ready to spawn. Spawning refers to the process of laying eggs. Salmon swim upstream to their spawning grounds, which are often located in freshwater rivers and streams. Once they reach their spawning grounds, they lay their eggs in nests that they build in the gravel. After the eggs are laid, the salmon die.
The journey downstream is perilous for young salmon. They must navigate through predators, obstacles, and pollution. However, the journey is essential for the survival of the species. Salmon play an important role in the ecosystem, and their downstream migration helps to ensure that the population remains healthy.
