Scientific name:
Percidae

Natural spread:
northern hemisphere

the perches (family Percidae), to the better differentiation of other Barschartigen fishings also real perches named, all are on the northern hemisphere at home; there on the other hand, they live in the restrained zone. It is freshwater-fish, however, some types go also in not too salt-rich coast-waters. The real perches have two back-fins, that also are together interconnected with some types. The first back-fin carries thorn-radiations, that second soft Gliederstrahlen. The sheds are comb-shed (fish).

River-perch (Perca fluviatilis)) Most of the types of the family admittedly live in North American waters, however, "the perch" is the European river-perch, who is spread over whole Europe, for us. its two back-fins are separate. The gill-cover is equipped at the rear-edge with a thorn. The sallow one until dark-green fish is weak until powerfully vertically gebändert. Stomach-fins and anus-fin are brass-yellow until blood-red, the tail fluke usually reddish. Perches are found in all possible water-types, the most they estimate clear, standing or not to fast flowing, with water-plants of passed waters. The adaptable fish produced different location-types, that differ in color, food and holding back. One can assume that each loot, that helps become full for it and that can manage it according to the size, is all right with the perch. it is no actual "robbery-fish", however, the big perch doesn't spurn other fish; for the type of the "Jagdbarschs", they are even the reason-food.

Verbutten Some waters lodge masses of perches, that hardly can then grow because of the feed-shortage and still are dwarfs after numerous years of life. One then speaks of a "Verbutten of the continuances." With better food-offer, perches can measure already 9 cm after a summer, a length, that some copies hardly exceed in a densely busy residential-precinct in the whole life. "Record-perches" can 50 cm long and 5 kg heavy becomes.

Reproduction River-perches spawn in the flat shore-zones from March to May. The barely 2 mm big eggs is approximately 2 cm wide to one and until connected 1 m of long "spawn-band." The perches, Egli or Krätzer, are excellent food-fish; however, only the big copies are desired.

One very narrowly relative and practically immediately looking type, the yellow-perch (Perca flavescens), represents the European perch in North America. Yellow-perches remain somewhat smaller.

Zander (Stizostedion lucioperca)) From the consumer more highly valued as the river-perches becomes the Zander that is called in the Danube-area of Schill and at the plate-lake Fogosch. Zander are stretched as river-perches, colored not so colorfully and expelled as robbery-fish through a number of big fangs between numerous small "Hechelzähnen" in the wide mouth. Zander, that can become 1,30 m long and then are heavy 18 kg, gain usually however only weights by 5 kg. They have its main-spread in Eastern Europe. they love warmer, standing, through big plankton-occurrences (that is small and smallest animal and vegetable creatures) of clouded waters. Also the "Haffzander" of the Baltic sea are known. Further, they like the big, inert streams with hard reason. Smaller fish (Ukelei, Stint) are main-food. Spawn-time is from April to June. The parents-animals kick spawn-pits, the eggs stick at plant-work or stones. They much faster than the river-perches of growing Zander are moved also in pond-economies where one gives artificial "spawn-nests" to the Laichzandern from juniper-branches or brushwood. Zander were put into many waters, in which they were not native originally.

The Berschik much smaller with approximately 30 cm or Wolgazander (Stizostedion volgensis) are less predatory as our Zander; the fangs are much less trained.

As well, it is with the Meerzander (Stizostedion marina) from the Kaspischen sea, that gains a length of 60 cm after all. Further types live in North America.

Kaulbarsch (Gymnocephalus cernua)) Another perch-type native with us is the Kaulbarsch. People-names like "snot-perch" or "Pfaffenlaus" speak in behalf of its prestige not exactly. Usually, 18, at most 25 cm long, will remain Kaulbarsche it even smaller. For this reason, they are eaten only in some areas - there however is worth it as delicacy. The großäugigen Kaulbarsche, with which thorn-ray-y and soft-ray-y share is interconnected to only one back-fin, finds predominantly in the lower reaches of the streams and in flat seas, also in the Baltic Sea*-lagoons, one. they spawn between Marches and Mays. The eggs usually sit in strips or lumps on stones. Kaulbarsche live on small animals, they make themselves beside it unpleasantly noticeable as spawn-robbers. Today, the Kaulbarsch belongs to the endangered types with us.

Further types In the Danube-area, there are still the next relatives of the Kaulbarsches, the Schrätzer (Gymnocephalus schraetzer) and this, like this, long-stretched types Zingel (ace-pro zingel) and nerds (ace-pro nerds). It is loners, who are not especially frequent. The Schrätzer even is on the red list of the types threatened by the extinction. Remarkably, the Groppenbarsch (Romanichthys valsanicola) still is from Romania. it was discovered only in the year 1957 - no miracle, because it sees the Groppe deceptive like.
