The yellow perch (Perca flavescens), commonly referred to as perch, is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. Yellow perch are closely related, and morphologically similar to the European perch (Perca fluviatilis); however, the two are recognized as independent species based on anatomical and genetic differences. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch.

Latitudinal variability in age, growth rates, and size have been observed among populations of yellow perch, likely resulting from differences in day-length and annual water temperatures. Typically, northern populations of yellow perch live longer and grow to larger sizes.(contradicts size described under biology) However, southern populations of yellow perch generally grow much faster. In many populations, yellow perch often live from 9–10 years, with adults generally ranging from 4–10 inches in length.

The yellow perch has a yellow to brass-colored body and distinct pattern, consisting of five to nine olive-green, vertical bars, triangular in shape, on each side. Its fins are lighter in coloration, with an orange hue on the margins. The body is laterally compressed. The anterior portion of the body is deep, gradually tapering into a slender caudal peduncle. The opercle is partially scaled, and a single spine is present on the posterior margin.

As with all percid fishes, yellow perch have two dorsal fins. The anterior is convex in shape and consists of 11–15 spines. The posterior dorsal fin has a straight margin, consisting of one or two spines and 12–16 rays. The nape, breast, and belly of yellow perch are all fully scaled. A complete lateral line (50–70 scales) is present. The anal fin consists of two spines and six to nine rays. A single spine and five rays make up the pelvic fins, and the pectoral fins consist of 13–15 rays. The caudal fin of the yellow perch is forked.


Yellow perch are only found in North America; they are native to the Arctic, Atlantic, Great Lakes-St. Lawrence River, and Mississippi River basins. In Canada, its native range extends throughout Nova Scotia and Quebec north to the Mackenzie River. It also is common in the northwest to Great Slave Lake and west into Alberta. It is not native to any other areas of Canada. In the United States, the native range extends south into Ohio, Illinois, and throughout the majority of the northeastern United States. It is also considered native to the Atlantic Slope basin, extending south to the Savannah River.

The yellow perch has also been widely introduced for sport and commercial fishing purposes. It has also been introduced to establish a forage base for bass and walleye. These introductions were predominantly performed by the U.S. Fish Commission in the late 19th and early 20th centuries. However, unauthorized introductions have likely occurred from illegal introductions, dispersal through connected waterways, and use as live bait. Isolated populations now occur in the northwest and southwest portions of the United States. Currently, the yellow perch has not been introduced outside of North America. Introductions in Canada have been less intense than in the United States.


Yellow perch typically reach sexual maturity in 2–3 years for males and 3–4 years for females. They are iteroparous, spawning annually in the spring when water temperatures are between 2.0 and 18.6 °C. Spawning is communal and typically occurs at night. Yellow perch are oviparous, as eggs are fertilized externally. Eggs in a gelatinous strand (commonly 10,000–40,000), a characteristic unique among North American freshwater fishes. Egg strands are commonly draped over weeds, the branches of submerged trees or shrubs, or some other structure. Eggs hatch in 11–27 days, depending on temperature and other abiotic factors. They are commonly found in the littoral zones of both large and small lakes, but they also inhabit slow-moving rivers and streams, brackish waters, and ponds. Yellow perch commonly reside in shallow water, but are occasionally found deeper than 15 m or on the bottom.

In the northern waters, females often are larger, grow faster, live longer, and mature in three to four years. Males mature in two to three years at a smaller size. Perch do not grow as large in the northern waters, but tend to live longer.(contradicts size in description) Most research has showed the maximum age to be about 9–10 years, with a few living past 11 years. The preferred temperature range for the yellow perch is 17.6 to 25 °C (63 to 77 °F), with an optimum range of 21 to 24 °C (70 to 75 °F) and a lethal limit in upwards of 33 °C (91 °F) and a stress limit over 26 °C (79 °F). Yellow perch spawn once a year in spring using large schools and shallow areas of a lake or low-current tributary streams. They do not build a redd or nest. Spawning typically takes place at night or in the early morning. Females have the potential to spawn up to eight times in their lifetimes.

A small aquaculture industry in the US Midwest contributes about 90,800 kg (200,180 lbs) of yellow perch annually, but the aquaculture is not expanding rapidly. The yellow perch is absolutely crucial to the survival of the walleye and largemouth bass in its range. Cormorants feed heavily on yellow perch in early spring, but over the entire season, only 10% of their diets is perch. Cormorants and anglers combined harvest 40% of age-1 and age-2 yellow perch and 25% of the adult yellow perch population in Lake Michigan. Total annual mortality of adult yellow perch has not changed since cormorant colonization.

General description

Yellow perch is often recognized by its dark vertical stripes and gold or yellow body color. Perca is derived from early Greek for "perch" and flavescens is Latin for "becoming gold" or "yellow colored". Adult sizes typically range from 3.9–11.4 in (10–30 cm); though have been known to grow larger. The yellow perch has a laterally compressed body with an oval, oblong shape. The anal fins are a green or yellow-orange, the dorsal fin is an olive color, and the belly is cream-colored. The vertical bands fade as they near the belly. Spawning intensifies the bands in males, and they can be nonexistent in juveniles. The spiny anterior dorsal fin has 13 to 15 spines. The soft rear fins also have one or two spines, but which are mostly made up of rays that range from 12 to 15 in number. The pelvic fins are close together, and the homocercal caudal fin is forked. The operculum tip has one spine, and the anal fin has two spines. There are seven to eight branchiostegal rays. Yellow perch has many fine and sharp teeth. They are rough to the touch because of their ctenoid scales. Common names for the perch are yellow perch, American perch, and lake perch. Yellow perch are one of the smaller-sized members of the perch family (Percidae). Due to its ability to crossbreed and the similar morphology, the yellow perch is sometimes classified as a subspecies of the European perch. For over 100 years, Canada and the United States have been commercially harvesting yellow perch in the Great Lakes with trapnets, gillnets, and poundnets. In Canada, the estimated catch in 2002 was 3,622 tons with a value of $16.7 million, second only to walleye at $28.2 million. The greatest demand in the United States is in the north-central region, where nearly 70% of all yellow perch sales in the US occur within 80 km (49.7 mi) of the Great Lakes. Yellow perch is one of the easiest fish to catch, and can be taken in all seasons, and tastes great. Therefore, it is a desirable sport fish in some locations of the US and Canada. It even makes up around 85% of the sport fish caught in Lake Michigan.

Geographic distribution

Yellow perch are native to North America in the northern region east of the Rocky Mountains, including tributaries of the Arctic and Atlantic Oceans and the Mississippi River. Native distribution was driven by postglacial melt from the Mississippi River. It has been widely dispersed from its native range. Its distribution to other areas of the eastern US and Canada are due to its popularity as a sport and commercial fish, as well as being a forage fish for other sport fish species, such as bass or walleye. The current native and introduced range in the United States is through northern Missouri to western Pennsylvania to South Carolina and north to Maine. Introduced areas currently have not expanded outside of North America. These introductions were predominantly performed by the US Fish Commission in the late 1800s and early 1900s. The non-native dispersal was not as intense in Canada. It was primarily limited to the lakes in the Peace River drainage of British Columbia, but has currently expanded to other bordering areas since.

Yellow perch are commonly found in the littoral zones of both large and small lakes, but also inhabit slow-moving rivers and streams, brackish waters, and ponds. Due to human intervention, they are currently found in many man-made lakes, reservoirs, and river impoundments. The perch are most abundant in lakes which may be warm or cool and are extremely productive in smaller lakes where they can dominate unless controlled by predation.


Primarily age and body size determine the diets of yellow perch. Zooplankton is the primary food source for young and larval perch. By age one, they shift to macroinvertebrates, such as midges and mosquitos. Large adult perch feed on invertebrates, fish eggs, crayfish, mysid shrimp, and juvenile fish. They have been known to be predominantly piscivorous and even cannibalistic in some cases. About 20% of the diet of a yellow perch over 32 grams (1.1 oz) in weight consists of small fish. Maximum feeding occurs just before dark, with typical consumption averaging 1.4% of their body weight.

Their microhabitat is usually along the shore among reeds and aquatic weeds, docks, and other structures. They are most dense within aquatic vegetation, since they naturally school, but also prefer small weed-filled water bodies with muck, gravel, or sand bottoms. They are less abundant in deep and clear open water or unproductive lakes. Within rivers, they only frequent pools, slack water, and moderately vegetated habitat. They frequent inshore surface waters during the summer. Almost every cool to warm water predatory fish species, such as northern pike, muskellunge, bass, sunfish, crappie, walleye, lake trout, and even other yellow perch, are predators of the yellow perch. They are the primary prey for walleye Sander vitreus, and they consume 58% of the age zero and 47% of the age one yellow perch in northern lakes. However, in shallow natural lakes, largemouth bass Micropterus salmoides may be most influential in structuring the quality of yellow perch populations. In Nebraska's Sandhill lakes, the mean weight and quality of yellow perch is not related to invertebrate abundance, but is related to the abundance of largemouth bass. The three primary factors influencing quality panfish populations are predators, prey, and the environment.

In eastern North America, yellow perch are an extremely important food source for birds such as double-crested cormorants. The cormorants specifically target yellow perch as primary prey. Other birds also prey on them, such as eagles, herring gulls, hawks, diving ducks, kingfishers, herons, mergansers, loons, and white pelicans. High estimates show that cormorants were capable of consuming 29% of the age three perch population. Yellow perch have such an extensive impact on trout species in the bodies of water in which they were introduced and established, they caused a drastic change in the food habits and reduced the growth rates of the trout by more than 50% in some locations. Trout in lakes where perch have been introduced typically cannot compete successfully for the available food, and once yellow perch get established in small lakes, even intervention by the use of trout hatcheries has been shown to be ineffective. In Canada, yellow perch are effective at escaping predation by lake trout and other native fishes during summer due to their high thermal tolerance. Parasites and diseases in yellow perch are often shared with salmonids in eastern North American lakes. A few examples are: brain parasite Flavobacterium columnare, red worm Eustrongylides tubifex, broad tapeworm Diphyllobothrium latum, and parasitic copepods Ergasilus spp.

Perch are commonly active during the day and inactive at night except during spawning, when they are active both day and night. Perch are most often found in schools. Their vision is necessary for schooling and the schools break up at dusk and reform at dawn. The schools typically contain 50 to 200 fish, and are arranged by age and size in a spindle shape. Younger perch tend to school more than older and larger fish, which occasionally like to travel alone, and males and females often form separate schools. Some perch are migratory, but only in a short and local form. They also have been observed leading a semi-anadromous life. Yellow perch do not accelerate quickly and are relatively poor swimmers. The fastest recorded speed for a school was 54 cm/s (12.08 mph), with individual fish swimming at less than half that speed.

Life history

Yellow perch spawn once a year in spring using large schools and shallow areas of a lake or low-current tributary streams. They do not build a redd or nest. Spawning typically takes place at night or in the early morning. Females have the potential to spawn up to eight times in their lifetimes. Two to five males go to the spawning grounds first and are with the female throughout the spawning process. The female deposits her egg mass, and then at least two males release their milt over the eggs, with the total process taking about five seconds. The males stay with the eggs for a short time, but the females leave immediately. There is no parental care provided for the eggs or fry. The average clutch size is 23,000 eggs, but can range from 2,000 to 90,000. The egg mass is a jelly-like, semibuoyant and can reach up to two meters long. The egg mass attaches to some vegetation while the rest flows with the water current. Other substrate includes sand, gravel, rubble and submerged trees and brush in wetland habitat. Yellow perch eggs are thought to contain a chemical in the jelly-like sheath that protects the eggs and makes them undesirable since they are rarely ever eaten by other fish. The eggs usually hatch in eight to ten days, but can take up to 21 days depending upon temperature and proper spawning habitat. Yellow perch do not travel far during the year but move into deeper water during winter and return to shallow water in spring to spawn. Spawning occurs in the spring when water temperatures are between 6.7 and 12.8 °C. Growth of fry is initiated at 6–10 °C, but is inactive below 5.3 °C. Larval yellow perch survival is based on a variety of factors such as wind speed, turbidity, food availability, and food composition. Immediately after hatching, yellow perch head for the pelagic shores to school and are typically 5mm long at this point. This pelagic phase is usually 30–40 days long.

Sexual dimorphism is known to occur in the northern waters where females are often larger, grow faster, live longer, and mature in three to four years. Males mature in two to three years at a smaller size. Perch do not grow as large in the northern waters, but tend to live longer. Maximum age estimates vary widely. The age of the perch is highly based on the condition of the lake. Most research has shown the maximum age to be approximately 9–10 years, with a few living past 11 years. Yellow perch have been proven to grow the best in lakes where they are piscivorous due to the lack of predators. Perch do not perform well in cold, deep, oligotrophic lakes. Seasonal movements tend to follow the 20 °C isotherm and researchers have concluded water temperature was the most important factor influencing fish distribution. Yellow perch commonly reside in shallow water, but are occasionally found deeper than 15 meters or on the bottom. Their optimum temperature range is 21–24 °C, but have been known to adapt to warmer or cooler habitats. The common lethal limit is 26.5 °C, but some research has shown it to be in upwards of 33 °C with a stress limit at anything over 26 °C. To grow properly, yellow perch prefer a pH of 7 to 8. The tolerable pH ranges have been found to be about 3.9 to 9.5. They also may survive in brackish and saline waters, as well as water with low dissolved oxygen levels.

Current management

Managers employed management techniques at Drummond Island, Michigan, such as harassing the cormorants and killing them as needed. Overall, the harassment deterred 90% of cormorant foraging attempts while killing less than 6% on average at each site; yellow perch abundance increased significantly due to yellow perch being the predominant prey of cormorants by total number and weight at that lake. Lakes in South Dakota without suitable spawning substrate have had conifers introduced, such as short-needle spruce, to increase both spawning habitat and hatching success. Managers have identified seven key unauthorized pathways for the introduction of the yellow perch to non-native regions: shipping, recreational and commercial boating, construction of new canals and water diversions, releases from live food fish markets, releases from the aquarium and water garden trade, use of live bait, and illegal introductions to create new fisheries. The most likely unofficial pathways are illegal introductions, dispersal through connected waterways and live bait. Many authorized introductions by natural resources agencies have taken place, as well, due to the sport fishing demand.

In 2000, the parasite Heterosporis spp. was discovered in yellow perch in Wisconsin, and has since been found in Minnesota, Michigan, and Ontario. The parasite does not infect people, but can infect many important sport and forage fish including the yellow perch. It does not kill the infected fish, but the flesh of a severely infected fish becomes inedible when the fish dies and the spores are then spread through the water to infect another fish. That concerns commercial fisherman in the Great Lakes regions that depend on these fish. The infected perch are not marketable. The current infection rates are 5% of harvest. Viral hemorrhagic septicemia is another serious disease in perch in the Great Lakes region. It has already killed thousands of drum in Lake Ontario and caused a large die-off of yellow perch in Lake Erie in 2006. Ontario is restricting commercial bait licenses as a precaution against this disease. Outside its native range, very few diseases or parasites have been found.


Yellow perch are a popular sport fish, prized by both recreational anglers and commercial fishermen for their delicious, mild flavor. Because yellow perch are among the finest flavored pan-fish, they are occasionally misrepresented on menus within the restaurant industry. White perch, rock bass, and many species of sunfish (genus Lepomis) are sometimes referred to as "perch" on menus.

The voracious feeding habits of yellow perch make them fairly easy to catch when schools are located, and they are frequently caught by recreational anglers targeting other species. Perch will at times attack lures normally used for bass such a 3" tubes, Rapala minnows and larger curl tail grubs on jigheads,Small bright colored casting spoons, but the simplest way to catch them is to use light line, 4#–8# test and light jig heads, 1/32–1/16 oz. There are too many small soft plastic lure designs to mention that catch all panfish, but minnow shaped lures with a quivering tail work much of the time so long as the retrieve speed is slow and the lure fished at the depth the perch are swimming. Curl tail grubs require the slowest speed of retrieve and may not be preferred when the bite is slow.

Some good baits for perch include worms, live and dead minnows, small freshwater clams, crickets, and any small lure resembling any of these. Larger perch are often caught on large live minnow on a jighead, especially when fished over weed beds. Bobbers, if used, should be spindle type for the least resistance when the bait is struck, but small round Bobbers work well too, yet indicate any slight pull of the bait. Raising the rod top is usually more than enough force to set the hook.

Some yellow perch fisheries have been impacted through intense harvesting, and commercial and recreational harvest rates often regulated by management agencies. In most aquatic systems, yellow perch are an important prey source for larger, insectivorous species, and many fishing lures are designed to resemble yellow perch, though fish-eating fish do not have the intelligence to tell the difference between lures but are some times weary of lures.
