[15][16], Huso huso is a pelagic predator which local distribution is not influenced by the nature of the substrates, unlike most of the sturgeons which show demersal attitude. Bestěr – Acipenser ruthenus × Huso huso. Acipenser baerii), Russian sturgeon (A. gueldenstaedti), Atlantic sturgeon (A. oxyrinchus), sterlet (A. ruthenus) and sevruga (A. stellatus).

[6], Huso huso shows typical characteristics of sturgeons, i.e., elongated body, heterocercal tail, partially cartilaginous skeleton, naked skin, longitudinal series of scutes. Based on morphological features, H. huso has been classified into two subspecies, Huso huso ponticus and Huso huso maeoticus (Salnikov and Malyatskii, 1934). huso dauricus. However, during the growth Beluga sturgeon shows evident morphologic changes: Among all extant bony fishes, Beluga sturgeon may be considered a rival to the ocean sunfish (Mola sp.) 2014 Concours, Caviar Passion fête Noël et son nouveau site. Beluga of such great sizes are very old (continuing to grow throughout life) and have become increasingly rare in recent decades due to the heavy fishing of this species. It is a protected species listed in appendix III of the Bern Convention, and its trade is restricted under CITES appendix II. At one time, beluga sturgeons could migrate up to 1,000 km (620 mi) upriver to spawn but dams in almost every major tributary they utilize has impeded historic spawning routes.

Beluga caviar is considered a delicacy worldwide. This is in brief the accepted explanation of the fact that different individuals of the same long-migratory species spawned as far upstream as Danube river km 1700, while others spawned at river km 100. In both sexes, they will go to spawn every 4 to 7 years. Survives largely by artificial propagation. It is found primarily in the Caspian and Black Sea basins, and formerly in the Adriatic Sea. The Mediterranean population is strongly protected under appendix II of the Bern Convention, prohibiting any intentional killing of these fish.

The barbels are laterally compressed with foliate appendages, arranged in two pairs, originating midway or closer to the mouth than the tip of the snout.[6]. The beluga also rivals the great white shark (Carcharodon carcharias) and the greenland shark (somniosus microcephalus) for the title of largest actively predatory fish.[9][10]. It is edible. The surface of the skin is covered by fine denticles. Feasibility of collagens obtained from bester sturgeon Huso huso × Acipenser ruthenus for industrial use. The United States Fish and Wildlife Service has banned imports of beluga caviar and other beluga products from the Caspian Sea since 6 October 2005, after listing beluga sturgeon under the U.S. It is little known about the diet of the Adriatic population, it has been reported that in marine and brackish environments adult H. huso foraged primarily on molluscs (Cephalopoda, of which common cuttlefish, Sepia officinalis, and European squid, Loligo vulgaris, are particularly common in the Adriatic sea) and fish belonging to the families Gadidae, Pleuronectidae, Gobiidae, Clupeidae, Scombridae and Mugilidae, but also on big crustaceans; in the rivers, they fed mainly on local Cyprinidae.[8]. By The study demonstrates the effects of antigens on specific and non-specific immune response in bester (Huso huso x Acipenser ruthenus). Sokolov & V.P. In the present study, we used embryos from pairs of sterlet (Acipenser ruthenus), Russian sturgeon (A. gueldenstaedtii), Beluga sturgeon (Huso huso), and Siberian sturgeon (A. baerii). IUCN classifies the beluga as critically endangered. Abdominal distention occurred at an incidence of 1% (15 from 1500 fish) in the population of 1-year-old bester (Huso huso × Acipenser ruthenus). Juveniles feed on benthic invertebrates in rivers and shallow coastal waters, where they grow quickly, then, at the length of 8–10 cm, they become largely piscivorous. To make the long journey to very distant spawning grounds, sturgeons adopted to a two-stage migration strategy entering the river in fall and staying over winter in reaches of the river offering adequate substrate and water flow resting conditions. Thereafter, the larvae usually subsist on benthic invertebrates but at as small as 10 cm (3.9 in) in length will switch to a fish-based diet.

[9] Another specimen reportedly weighted 1,220 kg (2,690 lb) and measured 6.1 m (20 ft 0 in) in length. [24]. [13] Spawning biology and development of larval stages of sturgeons - the most ancient fish of the Danube - co-evolved with the formation of the Danube valley, resulting in very different survival strategies of their early life stages. The hybrid Bester sturgeon (Huso huso × Acipenser ruthenus) is one of the most important commercial fish species in the world. Ukazuje tedy jen část galerie omezenou na určitý taxon. About 360,000-7,700,000 eggs per female. Only very few locations of existing wintering and spawning grounds for sturgeons are presently known in the Lower Danube River, none in the Middle Danube River and Upper Danube River. The series of longitudinal scutes are five: dorsal (1 series, 9-17 scutes), lateral (2 series, one per side, 28-60 scutes each) and ventral series (2 series, one per side, 7-14 scutes each). Different diets have been observed throughout the distribution range of Beluga sturgeon, as well as according to the stage of migration of the spawners, anyway it mainly consists for adults in a great diversity of large fish (73% of the diet).
