Tilapia breeding methods and fish pond management are as follows:

I. Breeding conditions

? Before releasing the fry, the pond must be completely emptied of other fish, especially tilapia, removed, otherwise it will be the same hall for four generations, everyone competing for food and space, not conducive to the growth of tilapia; usually lime or tea bran powder to clear the pond, such as the use of quicklime, the pond should be dried first, thoroughly drained the pond, and then apply quicklime according to the 100kg/mu. Normal water injection and drainage should be filtered through a 30-mesh sieve to avoid other tilapia mixing into the pond.

2. Stocking density

If breeding fry, the stocking density of fry is 30000-100000 fishes/mu. If breeding adult fish, there are two modes, one is pure breeding of a single species, the stocking density should be adjusted according to the size of the breeding water body, to ensure that the fish pond is ventilated and permeable to light, with sufficient feed. Some bighead carp or catfish should be stocked to prevent incomplete pond clearing or mixing with other species of tilapia and wild miscellaneous fish growing and reproducing in the pond during drainage and irrigation. Secondly, three-dimensional multi-species mixing, mainly fish as omnivorous fish, mixing in the traditional four major fish and famous ponds to remove residual bait and feces.

3, feeding intensity

? The key is feeding, first of all, optimize the feed. Instead of choosing feed, we should choose the feed manufacturer, we should choose the brand feed produced by the big old factory with high safety coefficient; secondly, the floating material is preferred among the sinking material, semi-sinking material and floating material. The feed should be fed regularly, regularly and quantitatively, two meals a day, and the feeding time is best at 10:00 am and 3:00 pm. In the hot summer, especially when the weather is sultry, you can't feed the fish to avoid overfeeding, and if the dissolved oxygen is insufficient at night, it will damage the gastrointestinal digestion and absorption function of the fish.

4. Disease control

The fish not only grows fast and has a large body size, but also has a strong resistance to disease, it usually has little or no disease. It is usually susceptible to death from bacterial infection after wear and tear and damage caused during fishing or transportation. Especially in cold weather, after fishing or long-distance transportation is easy to water mold; fish fry in the pool on the day of sprinkling iodized water or chlorinated water in the whole pool.

5, daily management

Regulating water quality is the key link. Improve the sediment environment, morning and evening should check the fish pond, see the color of the water, smell the water, observe the activities of the fish, to prevent the fish from lack of oxygen. Especially in hot and muggy weather, once the floating head of the fish is found, the oxygenator should be turned on in time. If the water quality is found to be over-fertilized, feed should be reduced, new water should be injected, water concentration should be reduced or water should be changed; especially in summer, the aquaculture water level should be deepened, attention should be paid to the pond foundation and drainage and irrigation outlets, and it is forbidden for other tilapia to be mixed into the fish pond. At the same time, pay attention to improve the substrate environment, to create a good ecological environment for the healthy growth of fish.
