MORPHOLOGICAL AND BIOCHEMICAL STRUCTURE OF CASPIAN SPRAT (CLUPEONELLA CULTRIVENTRIS CASPIA)
The biological (length and weight, condition factor by Fulton) and biochemical characteristics (protein, lipids, mineral substances, α-amylase, maltase, alkaline phosphatase and morphotypes of homogenates) of the Caspian sprat caught in the Northern Caspian during 2008-2009 were studied. The increase in length and weight relations and sprat condition factor in the studied years is fixed. It was established that in 2009 with respect to the results of 2008 total lipids increased by a factor of 1.8 while the level of mineral substances increased by 1.5. α-Amylase activity of 30 % studied species exceeded that of alkaline phosphatase in sprat muscles by a factor of 3. The presence of morphological texture coloration is a result of functional changes in major (protein-lipid) components of fish homogenized tissue.
