Формирование популяций осетровых (Acipenseridae) Волго-Каспийского бассейна
Вопросы ихтиологии, 2014Представлен анализ динамики промысловых уловов и состояния популяций русского осетра Acipenser gueldenstaedtii, севрюги A. stellatus и белуги A. huso (Huso husо) в Каспийском море. В ретроспективе рассматривается роль естественного и искусственного воспроизводства в формировании популяций осетровых.

Olfactory Receptors in Acipenseridae Fish Larvae
1992Basic aspects of the development of the olfactory system of Acipenseridae occurs during the period between the embryo’s hatching and its period of independent feeding. It was found that actively feeding Acipenseridae larvae have the same types of olfactory receptor cells as observed in adults (Pyatkina, 1976).

Ultrastructure of the Caudal Neurosecretory System in Acipenseridae
1978The fine structure of the cells of the caudal neurosecretory system in Acipenseridae exhibits all characteristic neurosecretory features. They have large, polymorphic nuclei rich in chromatin, with numerous nucleoli. The nuclear envelope has many pores. Numerous intranuclear cytoplasmic invaginations are observed; these are characteristic of the nuclei

[Brain lipid biochemistry of the sturgeons Acipenseridae].
Zhurnal evoliutsionnoi biokhimii i fiziologii, 1976Brain lipids of 4 species of sturgeons-Acipenser güldenstädti, A. stellatus, A. ruthenus and Huso huso-have been investigated. In whole brain homogenates the content of the basic phospholipid families, their fatty acid composition as well as the content of glycosphingolipids-gangliosides, cerebrosides and sulfatides were studied.

Age and growth rate of Black Sea starry sturgeon (Acipenser stellatus, Pallas 1771) were studied based on analysis of pectoral fin spine sections internal structure. Time of annual growth marks formation was determined. Parameters of von Bertalanffy growth equation were estimated.

Crown cells are considered to be typical for the Saccus vasculosus of gnathostome fishes. In Acipenser ruthenus these cells could be found on the entire floor of the diencephalon by SEM. There is one accumulation of crown cells in the frontal Recessus praeopticus, one caudal to the optic chiasma and one on the floor of the Recessus lateralis.
