How to recognise it
The Peamouth (Mylocheilus caurinus) is a slender fish with a streamlined body. It typically has a greenish or bluish back, silvery sides, and a white belly. The fish can grow up to 20 inches in length. Its mouth is unique, featuring a small, terminal mouth with a slightly protruding lower jaw. The dorsal fin is long and extends nearly to the tail. The Peamouth is often confused with the Northern Pikeminnow (Ptychocheilus oregonensis). The key detail that separates them is the Peamouth's more rounded, less pointed snout.
Where it lives
The Peamouth is primarily found in the western United States, ranging from northern California to British Columbia. It inhabits freshwater rivers, lakes, and reservoirs. This species prefers shallow waters, typically between 3 to 15 feet deep. It often seeks cover in areas with submerged vegetation, rocks, or debris. In warmer months, Peamouths may move to deeper waters as temperatures rise, while in cooler months, they tend to return to shallower areas.
When it bites
Peamouths are most active from late spring to early fall, generally biting from May to September. They prefer water temperatures between 60°F and 75°F. Early morning and late evening are the best times to catch them. Weather changes, such as a passing front, can increase their activity. Windy conditions can also trigger feeding, while a full moon may lead to more nocturnal activity.
How to catch it
To catch Peamouths, use light tackle with a 6 to 10-pound test line. A size 8 to 10 hook is recommended. Effective rigs include slip bobber rigs or small jigs. For bait, try worms, small minnows, or artificial flies in sizes 1 to 3 inches. Colors like chartreuse, white, or natural patterns work well. Cast near submerged structures or along the edges of vegetation. Retrieve slowly, allowing the bait to mimic natural movement.
Size, age and the table
Anglers typically encounter Peamouths ranging from 10 to 15 inches. A trophy Peamouth is considered to be over 18 inches. The growth rate is moderate, with fish reaching sexual maturity around 3 to 4 years. Peamouths can live up to 7 years. They are edible and have a mild flavor, but care should be taken when handling them to ensure a successful release. Use wet hands or a wet cloth to minimize damage to their skin and scales.
