Rivers, lakes and ponds are the three major aquaculture bases in China. Especially in artificial fish farming, the application is obvious. Cage fish culture has less investment and quick effect, and its economic benefit may be several times that of conventional fish culture. Aquaculture facilities are simple and easy to use, and are deeply loved by aquaculture people. Cage fish culture has developed rapidly in rivers, lakes, reservoirs and even offshore natural waters. However, cage fish culture is relatively rare, and it is generally carried out in dense fish ponds.

The pond can be put in a cage for fishing.

1。 Structure and setting of the cage The length, width and height of the small cage are 1 m, which can be woven with thick fishing nets. The mesh of adult fish cage is about 3 cm, and the mesh of fish species is 1.2 cm. Weld the frame with steel bars with a diameter of 8 mm, or tie the frame with bamboo, and then fix it in the water with heavy stones.

2。 Breeding method 1. Selection of fry: choose fat, disease-free, harmless fish weighing more than 50g, and store 500 fish in each box. Before entering the fish box, the fish is disinfected with 3% salt solution. After entering the fish box, oxytetracycline was fed 10 day, and then every 20 days. 2. Concentrated feed and concentrated feed: properly mix feed and concentrated feed from local resources. Main ingredients: corn flour, alfalfa powder, bran, bean cake, etc. They are fed in groups. Feeding them two or three times a day can gain more than100g a month.

3。 Prevention of water pollution: move the cage in time, adjust the water level, create a suitable water flow environment, pay attention to disinfection with lime milk, and remove the water pollution source in time.

Four. Breeding conditions and advantages: cage fish culture can be carried out in ponds, ditches and rivers and can be moved at any time, which is very suitable for farmers.

The pond can be put in a cage for fishing. Cage fish culture has the advantages of less investment, quick effect and convenient operation. This is an economical and convenient breeding method. To raise fish in cages in ponds, the first thing to do is to set cages, followed by buying and breeding fry. In the process of aquaculture, we should pay attention to water quality management, change water and move cages in time, and adjust the water level to make fish have a fresh water environment. Cage fish culture can be carried out not only in ponds, but also in rivers and other places, which is very convenient!
