| Abstract: | Inter-specific hybrids were produced between the threatened catfish species Mystus gulio × Mystus montanus. The differences in percentage of fertilization and hatching between control and interspecies were significant. The survival of hybrid was significantly lower (24.80 ± 4.3%) when compared to control (95.1 ± 3.5%). Time difference in yolk absorption by hybrid (73.30 h) was higher than that of control (72 h). When compared to interspecific fertilized egg the hatching time (24-25 h) and viability of larvae of the control were significantly better. In hybrids more deformed hatchlings (52.7 ± 4.2 %) were noticed than the control (24.80 ± 4.3%). |
