Tilapia Fish Farming Cage Culture

Tilapia are very adaptable fish and can breed in cages, despite  the high fish density and lack of spawning substrate. Female fish  grow slower than male fish and the result of these two factors is  reduced and uneven growth  of the fish. To overcome  this problem, Nam Sai  Farms produces all male  fish by feeding male  hormone-impregnated fish  meal for 21 days to  hatchlings. The fish at Nam Sai are tested on a monthly basis by  gonad squash method and are very close to 100% male.  Furthermore, they are male for life, despite what some people would  have you believe. Growth of these fish is much quicker and more  uniform than mixed sex fish.
