The cost of raising 1 kg tilapia is about that of 3.5 yuan. When stocking fish, generally choose healthy and energetic fish with a body length of about15cm and a weight of more than100g. The optimal stocking density is 0/600 fish per mu/kloc-with a certain proportion of clean water fish, such as winter fish, bighead carp and silver carp. The crude protein content of fish feed should reach 35%-40%, which can promote the rapid growth of fry.

First, the cost of farming 1 kg tilapia

1, the cost of tilapia culture includes the introduction of fish species, rental of sites, feed feeding, disease prevention and daily management, etc., and the average cost is about 3.5 yuan/kg.

2. At present, the market price of tilapia is about 4.5-6.5 yuan/kg, and the profit per kg is about 1-3 yuan. Generally, the profit per mu can be about 2,000-4,000 yuan.

3. When stocking fish, generally choose fish with a body length of about15cm and a weight of more than100g. Choose tilapia fry with the characteristics of neat specifications, strong physique, lively swimming and fast growth. The optimal stocking density is 0/600 fish per mu/kloc-with a certain proportion of clean water fish, such as winter fish, bighead carp and silver carp. The crude protein content of fingerling feed is required to reach 35%-40%. With green feed as an auxiliary, it is required that the green feed used has no pesticide accumulation and residue.

2. How long is the breeding cycle of tilapia?

1, tilapia culture cycle is generally about 5-6 months. Increasing water volume, reducing water fertility, eating aerators and strengthening the prevention and control of fish diseases can shorten the tilapia breeding cycle. The feeding time of tilapia fry is generally in the middle of April, and the temperature rises gradually after the spring, and the best feeding time is when the water temperature is stable at 15℃ or above.

2. Pay attention to the control and prevention of fish diseases, and disinfect ponds and fish schools at intervals.

3, according to the weather changes or the growth of fish, reasonable feeding.

4. In summer, insist on turning on the aerator every day, and use the stirring effect of the aerator to increase the dissolved oxygen in the water body, so as to promote the decomposition of the organic matter of the bottom impurities and prevent the fish from floating head due to lack of oxygen.

5. During the breeding period, the fish that have reached the market requirements will be cleared out of the pond to reduce the density in the pond, so that the fish with small specifications can grow faster.
