Greater yield and uniformity in tilapia farming
Mono-sex tilapia farming is a bit more complicated but it's worth it. It allows for mostly male tilapia to be grown, sometimes up to 98% male. This is done using methods like picking out males and females by hand, using hormones, or natural methods. Using specially bred tilapia (GIFT) is best for commercial farming. Using hormones can change most fish from female to male, usually about 98% of them. Another method uses changes in temperature after the fish hatch, turning about 86% of them into males. The natural method gives you all-natural males. It's important to know that with hormone-treated fish, some might look like males but genetically they're still females.
