Genetics
Genetics is the study of how different qualities, called traits, are passed down from tilapia broodstock to fry. Genetics helps explain what makes a fish unique, why related fish are very similar, and why some diseases or abnormalities run in strains or not.

In tilapia farming, selection on traits can be used to improve an entire fish stock by supporting higher survival rates, improved growth rates or increased resistance against pathogens. To be able to select on more desirable genetics, it is important to understand how tilapia is reproduced and how the selection is done. Good and well-managed broodstock, egg and fry management all play a pivotal role in improving fish genetics. Farming fish that is a result of careful genetic selection has a significant positive effect on farm profitability.
