Резюме: The aim of thе study is to determine the effect of sudden temperature changes on the behavior and
survival rate of European catfish larvae. The experiment was carried out with 100 larvae (body weight
86.17 ± 20.07 mg and length 22.67 ± 1.44 mm) in laboratory conditions and control temperature of 25
°C. Five temperature variants were studied, with increasing and decreasing temperature at 5 °C interval.
Thermal shock, expressed in change of the behavior, was observed in Variant B (final temperature of
35 °C), Variant D (final temperature of 15 °C), and in Variant E (final temperature of 10 °C).
