fiskemigrasjon

Fiskemigrasjon refers to the seasonal or cyclical movement of fish between different bodies of water. These migrations are often triggered by factors such as reproduction, feeding, or changes in water temperature and salinity. Many fish species undertake long-distance journeys to reach specific destinations for spawning, returning to their natal waters to breed. Other migrations are driven by the availability of food resources, with fish moving to areas where prey is more abundant. Changes in environmental conditions, such as the onset of winter or the melting of ice, can also cue fish to migrate to more favorable habitats. Understanding fiskemigrasjon is crucial for fisheries management, as it helps in identifying critical habitats and ensuring the sustainability of fish populations. Dams, pollution, and overfishing can disrupt these natural movements, impacting the survival and reproductive success of migratory species.
