MORPHOMETRIC FIGURES OF PERSIAN STURGEON BROODSTOCK OF HILINSKI STURGEON HATCHERY ^{[№ 5 ' 2016]}
For a long time the decision on necessity of creation of sturgeon broodstock at the existing sturgeon hatcheries (SH) on reproduction was extremely difficult in biological terms and costly in economic. However, the catastrophic decline of natural sturgeon stocks in the Caspian Sea forced the experts to reconsider their opinion on the question of the formation of broodstock, as SH began to feel the acute shortage of breeders. Persian sturgeon lives mainly in the middle and South Caspian, preferring the warmer water. The Persian sturgeon catches are dramatically reduced. While fishing in the sea near the Iranian coast, when caught immature fish, the number of the spawning population is reduced, resulting in reduced volumes of natural reproduction. In Persian sturgeon, in contrast to the Russian, more elongated body with a bluish tint, with a longer head component to 17.6 % of body length, and a bigger snout and postorbital space. The building has a distinctive snout: in profile it is clearly bent downwards and comparatively short and pointed, but more bulky than that of the Russian sturgeon. Persian sturgeon is different from Russian also a relatively large thickness and volume of the body. The aim of this work was carried out to characterize the morphometric parameters of the Persian sturgeon Hilinski SH, Republic of Azerbaijan. Work on the formation of broodstock in terms of Hilinski SH began from annual fish of age with an average weight of 54.5  ± 1.2 age fish renovation group morphological indices were little changed, with the exception of data related to body length, height and width of the head. Morphometry data obtained in the further cultivation of broodstock confirm the previous conclusion that with age, growth in length is reduced, increasing the girth of the body, which is supported by data length to end of middle beam, antianal distance, anteventral distance. The indicators characterizing the size of the parts of the head should be considered as species specific differences.
