The study looked at how profitable tilapia farming is in different ways. They visited 47 farms in China and found that all were owned by men. Most farmers were between 30 and 50 years old, and half had training. The farms were around 4.7 hectares in size, mostly for pond farming. It costs about $1168 to produce tilapia, but farmers make a profit. Tilapia farming is a good investment, especially in monoculture. To make more money, farmers should increase fish stocking and improve feed use. They can sell fish for a good price and look for new markets like Africa.
