Název v původním jazyce

Induced artificial and semiartificial spawning by Supergestran in perch (Perca fluviatilis L.) under different temperature

Popis výsledku v původním jazyce

In total, 4 groups of broodstok were used to test of semiartificial and artificial spawning under different temperature (10?0.2 °C and 15?0.2 °C) in perch. All females were injected intramuscularly by uniform hormonal treatment (Supergestran preparation,50 ?g GnRHa. kg-1 BW). Males were not hormonally treated. After spawning, time of latency, female?s fecundity, hatching rates and broodstock survival rates were found in tested groups. All realized values were compared among all groups by ANOVA, Tucky?smultiple comparison test (P< 0.05). Longer latency was found in semiartificial compared to artificial spawning under both temperatures (under 10°C about 14.5?1.1 h and under 15°C about 57.6?5.2 h). Very similar fecundity of females was found in all groups. The highest hatching success (72.9?12.3 %) was found in semiartificial spawning under 15 °C. The lowest hatching success (46.1?9.8 %) was recorded after artificial spawning under 10 °C. During semiartificial and artificial spawning, l
