| Trout are characterised by their annual spawning runs. They have a sea dwelling population called 'sea trout'. Land-locked populations still undergo spawning migrations. Lake populations migrate into feeder streams, while riverine populations often move upstream to shallow waters to spawn. They migrate at water temperatures from 6° to 10°C generally under all flow conditions (Ref. 26524). Spawning occurs in clear, flowing waters, usually less than 30 cm deep, over clean gravel. Homing behaviour has been recorded in spawning brown trout (Ref. 26525). Fertilised eggs are deposited in a depression in the gravel made by the female (Ref. 26525). |
