Abstract

The present work aimed to investigate the effect of incubation temperature on the embryonic development of the minor carp < em> Labeo rajasthanicus. To assess the embryonic development of L. rajasthanicus, eggs were incubated at five different temperatures (22, 26, 30, 34, and 38°C). Developmental stages were monitored by sampling embryos in these five different temperatures at particular intervals. The results showed that the eggs incubated at 38°C did not develop beyond the two-cell stage. The maximum duration for hatching and times to reach different life stages was observed at 22°C followed by 26°C. Hatching of eggs was observed after 20.27±0.29, 17.48±0.16, 15.03±0.13, and 17.13±0.20 hours of fertilization at 22, 26, 30, and 34°C respectively. The hatching time and time to attain different ontogenic stages were decreased with increased temperatures. This study demonstrated that incubation temperature significantly (p < 0.05) influenced hatching duration and ontogenic development in L. rajasthanicus.
