Distribution and Lifecycle
SPAWNING
Salmon and seat trout often enter the river months, even up to a year,
before spawning. By the time they reach the spawning beds, their appearance
has changed significantly.
Salmon
trout and sea trout spawn in loose gravel beds. The gravel is usually
of a mixed size with the stones varying from larger than a tennis ball
down to pea size; however finer sediments may prevent the free access
of oxygenating water to the eggs. Eggs are laid between mid-October and
February. Usually, trout spawn before salmon.
All salmonids, particularly brown trout and sea trout, will spawn in very small streams. Salmon and sea trout will also spawn in the main river down to tidal waters.
