Kokurewicz, B. (1970) The effect of temperature on embryonic development of Tinca tinca (L.) and Rutilus rutilus (L.). Zool. Pol., pp. 317-337
Species | Development state | Trait | Primary Data | Secondary Data |
Rutilus rutilus | Egg | Temperature for incubation | Most numerous and healthy hatchings were obtained at temperatures ranging within 12 and 24°C | 12.0 °C |
Rutilus rutilus | Egg | Degree-days for incubation | Number of DD until mass hatching for series A in 1965: 297 [At 7.8°C],238 [At 8.2°C],187.5 [At 12.5°C], 151.3 [At 16.1°C], 86 [At 20.0°C], in 1967: 210.3 [At 8.1°C], 145.2 [At 13.4°C], 103.9 [At 21.6°C], 94.6 [At 23.9°C] | 1965.0 °C * day |
Rutilus rutilus | Spawning conditions | Spawning temperature | The temperature of water during spawning in seperate years amounted to 19.4 and 18.7°C | 19.4 °C |
Tinca tinca | Egg | Temperature for incubation | Of 2 cultures incubated at 14.5°C (containing about 300 eggs each) only a few larvas were hatched. In one culture incubated at 15°C only 5 teratogenic larvas were hatched. The highest temperature at which incubation was conducted amounted to 30.2°C. At this temperature the per cent of hatched out larva amounted to 40%. Cultures incubated at temperatures ranging within 21°C-24°C gave a highest per cent of hatched out larvas with a lowest per cent of abnormalities, the asynchronicity of their development was also minimal | 2.0 °C |
Tinca tinca | Egg | Degree-days for incubation | The number of DD used by embryos until mass hatching for series A in 1965: 129.3 [At 14.5°C], 93.7 [At 15°C], 83.2 [At 21.5°C], in 1966: 48.6 [At 16.2°C], 63.6 [At 21.8°C], 55.7 [At 24.7°C], in 1967: 83.4 [At 17.1°C], 72.4 [At 21.7°C], 55.6 [At 23.4°C], 53.6 [At 28°C] | 1965.0 °C * day |
Tinca tinca | Spawning conditions | Spawning temperature | The temperature of water during spawning in seperate years amounted to 22 and 19 | 22.0 °C |
