Perca flavescens - Yellow perch Perca fluviatilis - European perch Perca schrenkii - Balkhash perch |
The European perch (Perca fluviatilis) is found in Europe and northern Asia. It is 15-60 cm long, and may weigh up to 10.4 kg. It is usually dark green with red fins. It has been successfully introduced in New Zealand and AustraliaAustralia is the sixth-largest country in the world (geographically), the only one to occupy an entire continent, and the largest in the region of Australasia. Australia includes the island of Tasmania, which is an Australian State. Its neighbouring count where it is called redfin perch.
The Balkhash perch (Perca schrenkii) is found in KazakhstanKazakhstan ( Kazakh: #x49A;қ Qazaqstan Russian: Kazakhstan , also spelled Kazakstan is a country that stretches over a vast expanse of Asia and a former republic of the now extinct USSR. It has borders with Russia, the People's Republic of China, and; in Lake BalkhashLake Balkash (sometimes written as Lake Balqash is a large lake in southeastern Kazakhstan, the second largest in Central Asia after the Aral Sea. It is part of the huge west/central asian endorheic basin that includes the Caspian and Aral seas. The lake and Lake Alakol . It is very similar to the European perch, and grows to a comparable size.
In the USThe United States of America also referred to as the United States U. America ¹ or the States is a federal republic in central North America, stretching from the Atlantic in the east to the Pacific Ocean in the west. It shares land borders with Canada in and CanadaCanada historically the Dominion of Canada is the second-largest, and northernmost, country in the world. It is a decentralized federation of 10 provinces and 3 territories, governed as a constitutional monarchy, and formed in 1867 through an act of Confe there is the smaller (10-25 cm long, 1.4-4.5 kg in weight) and wider-mouthed species, the yellow perch (Perca flavescens). It is paler and yellowish and its fins are not as red; although recognized as a distinct species[1], the yellow perch may be a subspeciesIn taxonomy, a subspecies is the taxon immediately subordinate to a species. Members of one subspecies differ morphologically but sometimes only genetically from members of other subspecies of the species. Conventions Conventions regarding infra-specific of the European perch (in which case its binomial name would be Perca fluviatilis flavescens). This view is supported by successful cross-breeding of the two species, which has generated faster growing offspring[2]. However, this may be an example of interspecies hybrid vigor and it is unclear whether or not these hybrids are viable.
Perch have ctenoid scales . When looking through a microscopeA microscope is an instrument for viewing objects that are too small to be seen by the naked or unaided eye. The science of investigating small objects using such an instrument is called microscopy, and the term microscopic means minute or very small, not, the scale look like a plate with growth rings and spikes on the top edges. Externally the anatomy of perch is simple enough. On the dorsal side of the fish, there consists a upper maxilla and lower mandible for the mouth. A pair of nostrils. Two lidless eyes. On the posterior sides are the operculum, which are used to protect the gills. Also there is the lateral line system which is sensitive to vibrations in the water. They have a pair of pectoral and pelvic fins. On the anterior end of the fish, there are two dorsal fins. The first one is spiny and the second is soft. There is also a caudal fin and anal fin. Also there is a cloacal opening right behind the anal fin.
The perch spawns at the end of April or beginning of May, depositing it upon weeds, or the branches of trees or shrubs that have become immersed in the water; it does not come into condition again until July.
The best time for fishing for perch is from September to February; it haunts the neighborhood of heavy deep eddies, camp sheathings, beds of weeds, with sharp streams near, and trees or bushes growing in or overhanging the water. The baits for perch are, minnows, red, marsh, brandling or lob worm s and shrimps. The tackle should be fine but strong, as with a fish bait a trout or pike may frequently be hooked. Perch, unlike fish of prey, are gregarious, and in the winter months, when the frosts and floods have destroyed and carried away the beds of weeds, congregate together in the pools and eddies, and are then to be angled for with greatest success from 10 to 4 o'clock, at the edge of the streams forming such eddies.
