Yellow Perch

Physical Characteristics

Oblong, compressed body with a light yellow/greenish gold hue. It features 6 to 8 dark vertical bands on its sides, two dorsal fins (the first with sharp spines), and reddish-orange pelvic and anal fins. Scales are ctenoid, giving a rough texture.

Habitat & Distribution

Native to North America, they inhabit clear, cool lakes, reservoirs, and slow-moving rivers with moderate vegetation. They are found from the northern United States through southern and central Canada.

Size & Weight

Commonly 15–25 cm (6–10 in) and 200–500 g. Maximum recorded length reached 50 cm (almost 20 in) and weights up to 1.9 kg (4 lb 3 oz).

Similar Looking Species

European Perch (Perca fluviatilis), which is generally larger with more intense red fins, and Walleye (Sander vitreus), which lacks the prominent dark vertical bands and has a larger, more pointed mouth.

Ecological Role

A key intermediate species in the food web acting as both a predator of zooplankton and small invertebrates and as a primary prey source for larger predators like northern pike and walleye. Classified as Least Concern (IUCN) across its range.
