Hatchability and survival of H. longifilis fertilized at varying latencies
In determining the optimum latency period of H. longifilis, of which the hatchability and higher Survival percentage were used as a determining factors to determine the optimum latency period of H. longifilis. The result from these varying latencies period shows that the best latency periods at the ambient temperature of 26degreesC, that support mass production and higher survival of H longifilis ranges between 15-19 hours. There was low or zero hatchability from the egg stripped early and the one stripped late.
