This issue is primarily due to the significant difference in growth rates between male and female tilapia. Male tilapia tend to grow faster, as females allocate a considerable amount of their energy to the production of eggs and fry. Consequently, the production of all-male tilapia has become an essential strategy for the aquaculture industry. Initial attempts at producing all-male tilapia involved the use of closely related species, such as Oreochromis hornorum, O. niloticus, O. aureus, and O. mossambicus crosses. Some of these hybridizations yielded nearly 98% male fish. However, hatchery production o...
