ABSTRACT


Effects of temperature (10; 14; 20; 24; 30°C) on the duration and course of embryogenesis, embryo movements in tench Tinca tinca (L.) were observed vertically and horizontally using two set-ups, each consisting of a microscope, digital camera, monitor, video recorder, and a computer. The results showed that small tench eggs including the eggs cells of
v = 0.49 ±0.4 mm3, had sticky egg shell, whose external part had an irregular structure and a few openings that closed rather quickly upon hydration. However, on the internal part of the shell there were oval pores present throughout the entire embryogenesis. During the embryogenesis, which at 24°C lasted approximately 840 H° following observations were made: sideways situated germinal disc due to the lack of the lipid droplet was a characteristic for the cyprinid fishes; yolk sac was divided after approximately 415 H° into two parts; specific somatic and "trembling" embryo movements. Right after the hatching the individuals whose mean length was 3.49 ±0.54 mm had a small (v = 0.21 ±0.15 mm3) yolk sac. The early stage embryogenesis was retarded in the temperatures that were too low.

Key words: tench Tinca tinca (L.), embryogenesis, egg, embryonic morphometry.
