Abstract
Interannual dynamics of physiological and biochemical indicators of blood, muscles, gonads and liver of the Caspian vobla is studied. Data in 5 years are generalized and multidirectional changes in quantitative characteristics of these indicators – hemoglobin, total serum protein, β-lipoproteids, cholesterol, general lipids and water-soluble protein in interannual aspect are revealed. The analysis of the obtained data is carried out taking into account the period of the annual cycle of vobla – in the prespawning (the IV SZG) and the prewintering (the III SZG) periods. The average amount of hemoglobin in blood of vobla did not go beyond the norm of the spawning state and preparation to wintering at the most part of the studied individuals. During the spring periods of 2009–2013 the content of the total serum protein varied from 45.97 to 58.10 g/l, during the prewintering periods – from 44.52 to 69.58 g/l. It is established that during the spawning periods, the average content of β-lipoproteins in blood serum is much higher than during the prewintering periods. During the spawning periods of 2009–2013 the cholesterol level in blood serum was 1.74–2.89 g/l, the total lipids – 11.10–15.95 g/l, during the prewintering periods – 2.30–6.14 g/l and 12.68–19.04 respectively. Data on quantity of the general lipids and water-soluble protein in muscles, gonads and liver showed their relative quantitative stability in 2009–2012. Since 2013 the tendency of increase of accumulation of lipid and protein components in the studied tissue has been noted.
