The Peamouth Chub

Range and Identity

Mylocheilus caurinus occurs in western North American systems including the Columbia and several British Columbia drainages. It is distinct from Northern Pikeminnow and Redside Shiner, although hybrids involving these fishes have been studied. Parent-species records should not automatically be assigned to hybrid entries.

Habitat and Behavior

Adults use lakes and slow-flowing parts of small to medium rivers, commonly near vegetation. Newly hatched fish school near shore before moving into deeper water during summer. Limited brackish-water tolerance is recorded but does not make every population a marine one.

Food and Life History

Foods include aquatic and terrestrial insects, planktonic crustaceans, mollusks and occasional small fishes. Spawning groups gather close to shore in very shallow water. The maximum reference is thirty-six centimeters total length, while common measurements expressed as standard length use a different endpoint.
