Breeding and Life Cycle

Each freshwater fish species in the UK has a unique breeding and life cycle. Let’s explore them further.

Atlantic Salmon

Atlantic Salmon breeds in freshwater rivers and streams. They migrate from the ocean to their breeding grounds, where they lay their eggs. The eggs hatch into fry, which then grow into smolts. The smolts migrate to the ocean where they mature and then return to their breeding grounds to spawn.

Brown Trout

Brown Trout breeds in freshwater rivers and streams. The female lays her eggs in a nest called a redd, which is excavated in the gravel bed of the river. The eggs hatch into fry, which then grow into parr. The parr migrate to the ocean where they mature and then return to freshwater to spawn.
