Most tilapias are omnivorous and often eat plants and debris in the water. This fish can also breed in small waters. It can even grow in rice fields. It usually lives in fresh water, but can also live in salt water with different salt contents. It can survive in shallow water in lakes, rivers and ponds.

Artificial breeding:

1. Fish cultivation

The pond area is 667-3333 square meters (1-5 acres). The pond should be cleaned and disinfected about half a month before the seedlings are released, and then filled with water. The water depth should be controlled at 0.8-1 meter. Apply about 500 kilograms of manure and green manure every 667 square meters as base fertilizer to keep the transparency of the pool water at about 25 centimeters. About 100,000 seedlings are placed per 667 square meters. In addition to applying basic fertilizer, soy milk is poured on the seedlings every day to strengthen the seedling cultivation. When the water temperature is about 25°C, after 15-20 days of cultivation, the fry can grow to about 1 g/tail, and they can emerge in time to be raised as commercial fish.

2. Commercial Fish Breeding

Pond breeding of Tilapia is the same as other tilapia breeding techniques, and a variety of feeding modes are possible. But at that time, the main promotion was mixed culture. What this refers to is that the four major species of fish are mainly raised, and the lucky fish is only raised as a matching species. In ponds where fat-water fish are generally raised, stocking can be carried out according to the water temperature as long as the water temperature can be stably maintained above 18°C.

3. The stocking specifications are 5-15g/tail for small ones, and 25-30g/tail for large ones. The size of early-breeding seedlings is smaller, but it should not be less than 3g/tail. Stocking density generally depends on the size of the seedlings and the source of the seedlings. As an adult fish pond mainly composed of four major species of fish, every 667 square meters can be stocked with 200-1,000 lucky fish. The fry that are hatched that year are raised for 150 days, and the individual fish can reach 150-250 grams. When mixed with four domestic fish, the individual output is as high as 150-500 kilograms per 667 square meters.
