The Peamouth (Mylocheilus caurinus) is a freshwater fish native to the Pacific Northwest of North America. Typically found in lakes and slow-moving rivers, it is easily recognized by its slender body and silvery appearance. Although not a primary target for sport fishing, Peamouths are known for their seasonal migrations into streams for spawning, where they can be caught in large numbers. They are omnivorous, feeding on a variety of aquatic plants, insects, and small invertebrates.

Peamouths thrive in lakes, rivers, and streams with moderate to slow currents
They prefer clear or slightly turbid waters with sandy or gravelly bottoms
These fish are omnivores, feeding on algae, aquatic insects, and small crustaceans
Peamouths often gather in schools, especially during their spawning migrations
Spawning occurs in late spring, usually in shallow, gravel-bottomed streams or along lake shores
During spawning, large schools of Peamouths congregate, making them easier to observe and catch
After laying eggs, adults return to deeper waters, leaving the eggs to develop on their own
Juveniles remain in shallower areas until they grow large enough to join adult populations in deeper waters
