Yellow Perch

Perca flavescens · also called lake perch, ringed perch

Least Concern → carnivore Rivers & wetlands

The yellow perch is the golden, black-barred fish that a huge number of North Americans caught first, from a dock as a kid, and that a huge number then ate, filleted and fried. It is one of the most popular panfish on the continent, and one of the most important prey fish in a northern lake.

Overview

Perca flavescens is a golden to brassy fish with six to eight dark vertical bars, orange lower fins, and two separate dorsal fins. It lives in the cool, weedy water of lakes, ponds, and slow rivers across northern North America, schooling near the bottom by day and eating insects, crustaceans, crayfish, and small fish.

In the middle of the food web

Abundant and mid-sized, it is eaten by nearly every larger predator in the lake — walleye, pike, bass, muskellunge, burbot — so its numbers shape how those fish do.

The angler’s fish

Its firm, sweet, white flesh is rated among the best of any freshwater fish, and it keeps feeding under winter ice, making it a mainstay of both summer and ice fishing. In spring the female drapes her eggs over brush in a long accordion-folded jelly ribbon holding tens of thousands of eggs.

Status

Least Concern and abundant. In lakes with too few predators, perch tend to overcrowd and stunt into vast numbers of small slow-growing fish.

Yellow Perch: common questions

Is a yellow perch the same as the perch in Europe?

They are close relatives, not the same species. The European perch, Perca fluviatilis, and the North American yellow perch, Perca flavescens, are the two main members of the genus Perca, they look very similar, with the same barred golden body and twin dorsal fins, and they live very similar lives in cool lakes and rivers. The European perch tends to grow a bit larger and often has redder fins. Both are excellent eating and popular with anglers, and both give their name, through the family Percidae, to the walleye, the sauger, and the many small darters, which are all perches in the broad sense.

Why is yellow perch so popular to eat?

The flesh is the main reason. Yellow perch fillets are white, firm, fine-flaked, and mild with a slightly sweet flavour, they hold together well when fried, and many people rank them at or near the top of freshwater fish for the table, ahead of walleye in some opinions. The fish are also abundant, catchable by beginners, available year-round including through the ice, and a convenient size for a pan, hence panfish. In the Great Lakes region the fried perch dinner is a fixture of restaurants, church fish fries, and lakeside taverns.

How is a yellow perch different from a walleye?

They are in the same family and share the barred, golden colouring and the twin dorsal fins, and a small walleye is sometimes mistaken for a big perch. The differences are these. A walleye is much larger, more slender and torpedo-shaped, silvery-olive rather than bright golden, and it has large, cloudy, light-gathering eyes and prominent canine teeth, neither of which the perch has. The walleye is a low-light predator that feeds mostly at dawn, dusk, and night and often in deeper or murkier water, while the perch is a daytime feeder that schools in the shallows and the weed beds, and the walleye regularly eats the perch.

What is the strange ribbon of eggs perch produce?

In spring, spawning yellow perch do not scatter their eggs or build a nest. Instead the female releases her whole clutch in a single continuous strand of jelly that folds back and forth on itself into an accordion or zigzag shape and is draped over submerged branches, weeds, or flooded brush. These gelatinous egg ribbons can be well over a metre long, hold tens of thousands of eggs, and are tough and somewhat distasteful, which seems to give the eggs some protection from predators. The ribbon form is distinctive enough that finding one is a reliable sign that perch have spawned in a lake.

Quick facts

Scientific name: Perca flavescens
Diet: Aquatic insect larvae, small crustaceans, and zooplankton when young, shifting as it grows to larger invertebrates, fish eggs, crayfish, and small fish including the young of other perch, feeding by day near the bottom in loose schools
Built for a name: It is golden-yellow to brassy green with six to eight dark vertical bars down the sides, orange lower fins in breeding fish, two separate dorsal fins the front one spiny, and sharp gill-cover edges, the classic look that the whole perch family is named for
A key link in the food web: It is abundant, mid-sized, and eaten by nearly every larger predator in a northern lake, walleye, northern pike, largemouth and smallmouth bass, muskellunge, burbot, and fish-eating birds, so its numbers strongly influence how those predators do
The panfish people prize: Its firm, flaky, sweet white flesh is widely considered among the best-tasting freshwater fish, and it supports both a large recreational fishery and, in the Great Lakes, a commercial one, with the fried perch dinner a Midwestern tradition
An ice-fishing staple: Yellow perch keep feeding actively under the ice through winter and school over predictable structure, which makes them one of the main targets of hard-water anglers across the northern United States and Canada
Egg ribbons: In spring the female drapes her eggs over vegetation and brush in a long, folded, accordion-like gelatinous ribbon that can be more than a metre long and contain 10,000 to 40,000 eggs, an egg mass unlike that of most other fish
Prone to stunting: In a lake with lots of perch and few predators, the population can become overcrowded and stunted, with vast numbers of small, slow-growing fish, which is why fisheries managers often want healthy predator numbers to keep perch in check
Range: Northern North America, native from the Atlantic provinces of Canada and the eastern United States west across the Great Lakes and the northern plains to the Rocky Mountains and north into the boreal lakes of Canada, and widely introduced elsewhere, in the cool, weedy, open water of lakes, ponds, reservoirs, and slow rivers.
Conservation status: Least Concern → ≈ Abundant and widespread across northern North America and not of conservation concern; it has been introduced well beyond its native range, is farmed in some areas, and its main management issues are overcrowding and stunting in predator-poor lakes rather than scarcity in the wild
