The prolific breeder, Morone Americana has been introduced to several of the Great Lakes like Lake Erie, Lake Michigan, Lake Ontario, and other smaller lakes in North America. The white perch appeared in the Great Lakes in the 1940s. They are thought to have entered through the Erie and Welland canals from the brackish waters of the Atlantic coastal region.

The domed back, white perch has silvery coloration. They can live in freshwater as well as brackish estuary waters of the Chesapeake Bay and its tidal tributaries, freshwater lakes, and ponds. For fisheries, increasing populations of the white perch invasive species is considered a menace. White perch are often mistaken with crappies. When talking about white perch vs crappie there are few differences. The white perch is a silvery fish but the crappie has blackish spots and a slight green tint on its body.  The white perch and crappies are both found in the tidal waters of the Chesapeake Bay.

White Perch Interesting Facts

What type of animal is a white perch?

White perch are small fishes that breed rapidly and are considered a nuisance in their aquatic habitats. They are abundantly found in the freshwater Winnebago lakes in Wisconsin, Pennsylvania, Lake Eerie, River Detroit, South Dakota, and Oklahoma. Apart from that, these sport fishes are found all across North America.

The white perch is not a welcome species in most lakes or ponds as they threaten the existence of several other fish species populations like the walleye and white bass. These voracious feeders eat the share of baitfish meant for other species, leaving the native fishes out of food and enough space.

What class of animal does a white perch belong to?

White perch are a species of fish belonging to the class Actinopterygii. They are mainly game fish. Another perch variety is the yellow perch.

What is a white perch's habitat?

White perch prefer to live in shallow lakes. They may spend the summer months in 15-20 ft (4.5-6 m) deep in water. In deeper water bodies, white perch populations are found gathered around rocky, submerged islands. In such places, they may live at the depth of 20-30 ft (6-9.1 m). Sometimes they also live near lake bottoms in soft mud. In spring, these fishes are mostly found in shoals near vegetated areas in clear water. Perch varieties are also found in slow-flowing rivers and creek pools. These fishes also thrive well in brackish water.

Who do white perch live with?

White perch species of fish are often seen in shoals or groups. They are predators and feed on invertebrates, small fish and their eggs, crayfish, and zooplanktons. These fish feed in groups in their natural habitats in canals, lakes, ponds, bays, reservoirs, and lowland rivers.

How long does a white perch live?

A white perch can live up to 17 years.

How do they reproduce?

The white perch species does not travel to the ocean for spawning and is thus considered to be a semianadromous fish. They are a category of fish that are in between the complete resident fishes and anadromous fishes that go out to the open sea or ocean for reproduction and spawning. White perch spawning happens in warm freshwater rivers. Spawning begins in March when the river water temperature is suitable. The adults move to slow-moving upstream rivers with fresh or mild brackish waters for spawning. The female white perch spawn only once a year.

Once the spawning is done the adults, males, and females both migrate downstream. In this species, parents do not wait for the eggs to hatch, or rear the larvae to their adult stage. The white perch adults prefer waters with salinity levels as high as 4.2 ppt for reproduction. The ideal waters are found in tidal or nontidal, gentle waters. From the mouth of Chesapeake Bay, resident white perch adults travel up to warmer tributaries to spawn.

Spawning happens in April. The eggs are laid by the females in form of long sticky bands. The length of the band depends on the size, nutritional status, and age of the female. Females wrap the eggs around aquatic vegetation and underwater rocks so that they do not drift away. The males then fertilize the eggs externally. A female can lay 150,000 eggs in a season. The eggs hatch in about a week. When the larvae are hatched, the yolk sac is attached to their body from which they draw nutrition. When it is finished the larvae feed on zooplankton.

The larvae and the juveniles remain in shallow waters of the river where they were born.  The juveniles spend the entire summer and autumn months in the same place. When they grow, the juveniles migrate downstream to live in brackish waters.

What is their conservation status?

The conservation status of the white perch is of Least Concern. These fishes are heavy breeders and their increasing population is considered a menace for several native freshwater fish species.
