Amostras de ovos fertilizados foram coletadas do tanque de incubação usando conta-gotas em uma petreta junto com água e os estágios de desenvolvimento foram observados sob microscópio e fotografados a cada intervalo de 10 minutos. Para o estudo histológico, os embriões foram fixados em lÃquido de Bouin recentemente preparado à temperatura ambiente durante 10-12 horas e lavados com água corrente da torneira durante 8-10 horas. Os córions foram removidos manualmente e os embriões nus foram embebidos em parafina e seccionados a 7 m com uma máquina micrótomo. As secções foram duplamente coradas com hematoxilina e eosina, montadas em DPX e observadas e fotografadas ao microscópio Olympus C35DX com câmara digital Coslab. O perÃodo de incubação do Bhakur foi de 13 horas após a fertilização a 3010C de temperatura da água. O presente trabalho gerou algumas informações importantes sobre o inÃcio da história de vida e as fases de desenvolvimento do Bhakur no Nepal. Este estudo ajudará os biólogos da pesca a compreender a biologia e a ecologia do peixe, o que poderá ser de grande utilidade para tomar medidas adequadas para o desenvolvimento sustentável da cultura, gestão e produção de raças indÃgenas necessárias para a piscicultura nas condições climáticas do Nepal.
