The effects of heat (40 °C, 1.5 min) and cold (2-4 °C, 60 min) shocks applied within 2nd, 8th, 15, and 30th minute after fertilization on the results of gynogenetic reproduction of common carp were compared. The sperm was inactivated using ultraviolet radiation. The temperature of fertilization and incubation of eggs was 22 °C. Greater numbers of larvae were obtained in the case of the heat shocks (0.3-3.4% of the incubated eggs) than of the cold ones (0-0.4%).

PL

Porównano wpływ szoków ciepła (40 °C, 1.5 min) i zimna (2-4 °C, 60 min) zastosowanych w 2, 8, 15 i 30 min po zapłodnieniu na wyniki gynogenetycznego rozrodu karpia. Plemniki inaktywowano przy pomocy promieniowania ultrafioletowego. Temperatura przy zapłodnieniu oraz inkubacji ikry wynosiła 22 °C. Większe ilości larw otrzymano przy zastosowaniu szoku ciepła (0.3-3.4% ilości inkubowanej ikry) niż zimna (0.0-0.4).
