The taimen lives in flowing water and is only occasionally found in lakes, usually near the … But the other side of the medal is a massive reduction of genetic diversity in those fish.

Zur Laichzeit im Mai wandert er in die Oberläufe und selbst in flache Bäche. Juraj Holčik, Karol Hensel, Josef Nieslanik, Ladislav Skácel:, „Creative Commons Attribution/Share Alike“. - In contrast to many trouts, salmons and chars, male huchen never grow a hooked mandible during the mating season. The largest reliably recorded specimen, caught in Russia’s Kotui River in 1943, measured an astonishing 83 inches long and weighed 231 pounds. Fifteen aquaria (200 L per aquarium) were randomly allocated into triplicate groups of 500 larvae. [3][4][5] Most mature fish caught weigh from 15 to 30 kg (33 to 66 lb). [2] Some authors consider the taimen to be a subspecies of the huchen, i.e. The fish travel upstream to smaller tributaries, where spawning occurs, and then drop back into the larger rivers.

The Huchen has been in sharp decline for the past 100 years, due mostly to habitat destruction and fragmentation.

But I could sadly find no further information about this.

Hard to believe the perch can out compete the shellcracker. Der Körper des langgestreckten Fisches erreicht eine Länge von einem Meter und mehr und hat ein Gewicht von 30 bis 60, in den sibirischen Flüssen bis über 80 Kilogramm. The huchen lives in fast-streaming water, and has a very elongated and spindle- shaped body.

The head of the huchen is comparably flat with a very wide mouth, and its jaws and tongue are equipped with well developed teeth.

Range and Species History

That’s a good call on getting JSTOR access at the public library; I’m going to check that out. I am sure all the info is tucked away in a thesis somewhere. It lives with several other huchen and some brown trouts in a big paludarium. Zolotukhin, S., Makeev, S., & Semenchenko, A. The tank colour did not significantly affect survival, condition factor, and feed conversion ratio among all the treatments (P > 0.05). It has also an unusually large adipose fin. None of the other species reach the same proportions of an adult Siberian taimen, but the huchen can grow to almost five feet long and weigh over 100 pounds.

The huchen also lives and even breeds in the river Isar, even right within the city of Munich.

The taimen is distributed from the Volga and Pechora River basins east to the Yana River in the north to the Amur River in the south.

While the taimen is sometimes (often illegally) harvested commercially, its low price and slow growth and reproduction make it more valuable as a game fish. They’ve got landlocked Sockeye Salmon in one south eastern waterway which lots of guys daydream about but the crazy fishermen been able to spread those everywhere. Because these fish are slow-growing–they take up to seven years to reach sexual maturity–populations can’t bounce back very quickly, and the taimen is listed as “vulnerable” on the “Red List” maintained by the International Union for Conservation of Nature.

There are lots of other power plant lakes outside of Texas that I’m sure guys wouldn’t mind hauling double-digit redfish out of too. volume 25, pages437–446(2017)Cite this article.

You can see some photos of exceptionally big specimens here. PubMed Google Scholar. Seine Nahrung besteht vorwiegend aus Karpfenfischen und Coregonen. [6] The average length is from 70 to 120 cm (28 to 47 in).

Because the fish tend to attack their prey near the surface, there is little “dredging”: the standard line is a weight-forward floater, although it pays to bring a multi-tip sinking line system, as well. For this reason, baits which imitate swimming rodents are quite popular huchen lures.

The taimen is not anadromous, but does show increased movement rates during the spawning season.

Hucho hucho taimen. Froese, Rainer and Pauly, Daniel, eds. They already destroyed those fisheries when they starting blasting rock and pouring concrete. The European version of Taimen occurs only in the drainage of the Danube river, in — for Russian standards — tiny countries such as Bavaria (part of Germany), Austria, Slowakia, Slowenia and Bosnia.

One of the most serious problems is the loss of most of its spawning grounds. They are aggressive and breed like rabbits don’t they? The greenie side is going “don’t you dare introduce foreign fish at the top of the foodchain, knucklehead”. They are one of the largest ‘salmonids’ on the planet, with an ‘average’ fish thought to weigh between 30 and 65lbs.

Zander dagegen bevorzugen langsamer fließendes und tieferes Wasser mit weniger Strömung, dahingehend sind beide Arten nur bedingt miteinander in Konkurenz, selbst wenn sie sich in manchen Übergangszonen sicher auch mal über den Weg schwimmen.

Most anglers use single-hand or switch rods in weights 8 or 9 with a reel capable of holding 200 yards of backing and featuring a drag system capable of slowing down a 60-pounder. According to the IUCN list of threatened and endangered species, "The main current threat to the species is the flow regulation from hydropower dams which impact the species, and their prey's, habitat and pollution. of Fish and Game aged it by using the otoliths. Taimen are known to live up to 55 years of age, which means they have a long time to get very very big. Er hat 26 bis 30 Schuppenreihen über der Seitenlinie, der Huchen nur 22 bis 26.
