Description of life cycle and mating behavior Female covers the eggs by restirring the sand and fine gravel (Ref. 9696). After hatching at 12 mm, larval brown trout remain in the gravel for 2-3 weeks until they are about 25 mm long, when they emerge to begin feeding in the water column. Brown trout are territorial and begin establishing territories as juveniles. Juvenile trout from lake populations move from their natal inlets to lakes during the first 2 years of life (Ref. 6390).
