Overview

Top of page

Huso huso (beluga or giant sturgeon) is the largest actinopterygian species (length up to 5.6 m, weight up to 1.5 t). Wild H. huso are found mostly in the Caspian Sea, Black Sea and the Sea of Azov basins. Based on morphological features, H. huso has been classified into two subspecies, Huso huso ponticus and Huso huso maeoticus (Salnikov and Malyatskii, 1934). Those in the Caspian Sea were subdivided into three populations: the Kura, Ural and Volga great sturgeons. The local populations (forms) exhibit slightly different characteristics of maturation, growth, fecundity. Seasonal (vernal and hiemal) races (forms) of H. huso can also be differentiated (Pirogovskii et al., 1989). It is a long-lived (more than 100 years), anadromous and eurybathic fish. H. huso is one of the three major commercial sturgeons. This species is considered a most valuable fish. The roe harvested from female beluga sturgeon is processed for the most highly-prized caviar. Sturgeon aquaculture has more than 130 years of history and been developing rapidly since the early 1990s. H. huso and bester (a hybrid of female H. huso and male Acipenser ruthenus) aquaculture has subsequently expanded into some regions of the world.

Description

Top of page Morphology

Huso huso is identified by its large, inferior crescent-shaped mouth (small and transverse in other sturgeon) and the gill membranes forming a fold across the isthmus. Snout is moderate and pointed, turning slightly upward. Lower lip is interrupted at centre. The caudal fin is heterocercal. Barbels are oval or flat, with leaf-like appendages, reaching almost to mouth. Five lines of scutes: one dorsal (11-14 scutes, first one smallest as distinct from the related species Huso dauricus), two lateral (41-52 scutes), two ventral (9-11 scutes). Scutes in older fish may be reabsorbed. The dorsal scutes are covered with skin in mature fish. The back is from dark grey and black to greenish, the ventral side is white. A very detailed description of beluga morphology on the basis of few dozen characteristics was given by Bemis et al. (1997).

Distribution

Top of page

Huso huso is distributed in the Black Sea (the Danube, Rioni, Dniepr, Dniestr and Bug rivers), the Sea of Azov (the Don and Kuban rivers), the Caspian Sea (the Volga, Ural, Kura, Gorgan and Sefid Rud rivers) and rarely in the Adriatic Sea (the Po river). H. huso has been extirpated from Austria, Croatia, the Czech. Republic, Hungary, Serbia Montenegro, Slovakia and Slovenia (FishBase, 2004). The presence of H. huso in Greece is questionable (Economidis, 1991).

It has been introduced to Armenia, China, Poland and the USA.
