What should be paid attention to in bream culture? How to breed bream?

1. In order to breed excellent bream, it is necessary to choose fish ponds and places with sufficient water resources. It is generally recommended to breed bream in a living pond, which can supply and drain water and needs clean and sufficient water resources. The size of the fish pond should be more than 2 mu, and the water depth should be 1.5 m to 3 m. In winter, the bottom of the pond should be exposed to the sun and cracked, and there should not be too much silt in the pond. The most important thing is not to discharge sewage. Ten days after the water is discharged into Tang Qian, the pond should be disinfected with quicklime, with 50 kilograms of quicklime per mu, and then discharged into the pond after exposure for ten days.

2. The stocking time of bream is generally around Tomb-Sweeping Day, and the fry after Tomb-Sweeping Day should be placed in a relatively cold place. In the choice of fry, it is required to be harmless and weak, and try to choose healthy and robust fry, the size of which is better than two fingers. Generally speaking, bream is mainly polyculture, such as silver carp, bighead carp, grass carp, herring and crucian carp. Mixed culture is helpful to the activity of Megalobrama amblycephala, about 200 Megalobrama amblycephala per mu, and 500-800 Megalobrama amblycephala per mu if Megalobrama amblycephala is the main species.

3. The water quality requirements of the cultured bream are generally the same as those of the four major fishes, with the water transparency of 25-30cm and the pH value of 7.6-8.5. The growing season of bream is from June to September, so it is necessary to pay attention to changing water, observing weather changes and correctly installing oxygen-increasing equipment. If it is rainy, windless and sultry, turn on the oxygen every morning. When you get up in the morning, you should pay more attention to the estrus of fish. If the fish's floating head is found to be short of oxygen, it should be irrigated in time and the oxygen should be turned on.

4. bream, like grass carp, is mainly grass or artificial feed, which is fed twice a day. If grass is fed, duckweed is generally recommended. Duckweed is small and tender, and bream likes it very much. You can also feed artificial granular feed such as peanut bran, wheat bran and corn flour. Feeding should be fixed at regular intervals to make the fish full.

5. Rural retail farmers don't need water disinfection, because their farming density is low and diseases don't occur. All the fish are fed in until they grow up, and basically do not need to be disinfected with drugs. If it is aquaculture, it is best to disinfect the water quality of the fish pond when you have time, about once a month, and use 20 kilograms of quicklime per mu to make limewater and sprinkle it all over the fish pond. Quicklime has the efficacy of sterilization, treatment and prevention. It can also purify water, prevent fish from getting sick, reduce the salinity and acidity of water, and contribute to the growth of fish.
