Abramis brama Spawning conditions Spawning temperature Our five years observations showed that the temperature during the spawning time (May and June) of bream fluctuated on spawning grounds between 13.5 and 26.5°C. On the other hand, when temperatures decreased below 20°C bream discontinuted spawning and left the spawning grounds. [...] Bream spawn at different temperatures depending on location: in the Volga River, spawning occurs between 10.0 and 13.5°C, in the Don River between 23 and 24°C, in Finland between 18 and 19°C, and in Masurian Lakes, Poland, bream spawn at about 17°C. In Kortowskie Lake, where spawners were caught, bream spawn at 20-21°C 20.5 °C
Abramis brama Egg Incubation time Based on graph => 220 hours [at 15°C] and 100 hours [at 25°C]. Regression equation for 50% of hatched embryos was Y = 910.1 - 65.88X + 1.318 X² (R² = 0.994) 33.44 days
Abramis brama Egg Temperature for incubation Incubated at 19-20°C 19.5 °C
Carassius auratus Egg Temperature for incubation Similarly, goldfish (Carassius auratus) eggs incubated at 12°C yielded significantly higher frequencies of abnormal larvae than those incubated at highest temperatures 12.0 °C
Scardinius erythrophthalmus Egg Temperature for incubation Incubated at 19-21 20.0 °C
Abramis brama Spawning conditions Spawning season Lake bream usually spawn in the beginning of June ['June']
Abramis brama Larvae Temperature during larval development Fastest growth of bream larvae (weight and length) was observed at a temperature of 27.9°C, the slowest growth was at 13.5°C. Fish reared at the highest temperature (34.0°C) grew much more slowly than those at 27.9°C, showing high weight and length variation. Lowest mortality was observed at 27.9°C, the highest was as 34°C. 27.9 °C
Esox lucius Larvae Sibling intracohort cannibalism The frequency of all cannibalistic attacks decreased in the order: highest>middle>lowest density Present
