refers to freshwater river and stream habitat with a gravel bottom where ladies can dig nests. Spawning habitats should have diverse pools, riffles, and runs simply because Grown ups assemble nests in locations with plentiful dissolved oxygen.
“This provides a baseline map we could use to focus on our attempts where they will be the most effective and be certain that salmon have access to chilly-water parts to avoid stress through the hotter time from the calendar year.”
