The biochemical characteristics of tench, Tinea tinea (L.), stocking material were examined with regard to the following parameters prior to and after wintering: bactericidal activity of the blood serum; blood glucose level (BG); total proteins (TP); blood serum protein fractions (albumins, and α-, β-, and γ-globulins). The study was conducted over the course of three years (1996 - 1998) on clinically healthy two-summer-old (fall) and two-year-old (spring) tench that ranged in body weight from 30 to 80 g. The study indicated that one of the parameters that characterized the resistance of tench in the wintering period was the relative stability of the bactericidal activity of the blood serum. Seasonal dynamics in the levels of blood glucose and total serum proteins were determined, and the levels of the former were higher in fall and lower in spring. The specific metabolic nature of different protein fractions in the blood serum of tench was characterized by percentage decreases of albumins and α- and γ-globulins and by increases of β-globulins.
