The white perch (Morone americana) is not a true perch but is a fish of the temperate bass family, Moronidae, notable as a food and game fish in eastern North America. In some places it is referred to as "Silver Bass". [citation needed] The common name "white perch" is sometimes applied to the white crappie (Pomoxis annularis). [3]
The species data on this page is taken from the Minnesota DNR, which also uses several labels to indicate a fish's status within Minnesota waters. An endangered fish species is near extinction in Minnesota, a threatened species is likely to become endangered within the foreseeable future, and a special concern species is either extremely ...
Moronidae basses move into inshore waters, estuaries and rivermouths in the summer, but in winter they move farther offshore and into deeper waters. The young fish gather in schools, but the adults appear to be more solitary. They are predatory, feeding mainly on shrimp and mollusks, as well as smaller fish. [8]
The number is similar to 2023 and shows a rebound from the low of 5 perch in 2017 but is a shadow of the catch from decades ago. In 1997, for example, the assessment netted 14,474 perch.
The eggs usually hatch in 8–10 days, but can take up to 21 days depending on 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.
The reproductive biology of the yellow bass is similar to that of the white bass, where spawning occurs during the spring with fish swimming into the tributaries to make spawning runs. [ 6 ] [ 7 ] Spawning usually occurs in moderately shallow waters during which the female lies on her side and exposes the eggs as the male fertilizes from above.
Lake whitefish spawn from September through January in water two to four metres in depth during the night. In the autumn, mature lake whitefish enter the shallows to lay their eggs on shoals of rubble and gravel. There is no parental care of the young. In the following spring the young will hatch. [8]
White crappies are also slightly more elongated than black crappies. [8] The white crappie is a deep-bodied fish with a flattened body, or a depth that is one-third of the length of the fish. White crappies have spinous rays and ctenoid fish scales found in advanced teleosts. The exposed part of the scale has tiny tooth-like projections (cteni).
