| Abstract: | The present study was designed to assess the embryonic development of Labeo rohita fertilized eggs incubated at four different temperatures (26, 31, 33 and 36°C) until hatching. Fertilization was carried out at ambient temperature (26 °C) and was considered as 0 h of embryonic development. Developmental stages were monitored by sampling embryos in different temperatures at particular intervals. Highest hatching percentage and least time for attaining each ontogenic stage were observed at 31N33N26N36 °C and were significantly different (pb0.05). The lowest hatching percentage and maximum time duration for attaining a given ontogenic stage were observed at 36 °C; this treatment also resulted in malformed embryos. Our study demonstrated that incubation temperature significantly (pb0.05) influences hatching duration, hatching rate and survival of L. rohita eggs. |
