Cage fish culture is a production method in which cages made of net pieces are placed in a certain water area for fish culture. Custom-made barrier nets believe that it has high output, low cost, small investment, easy management, land and water saving and energy saving, and effective development of large water fishery waiting points in rivers, lakes and reservoirs. At present, the output of cage fish culture is getting higher and higher, and the requirements for feed and feeding management are getting higher and higher. How is fish culture in cages? How to raise it? what should I be aware of?
Advantages of cage fish culture technology
1. Using large and medium-sized waters such as lakes, reservoirs, rivers, and shallow seas, harbors and other waters for fishery production can improve the utilization and utilization efficiency of land resources, without occupying arable land, borrowing water to return water, and using one water for multiple purposes.
2. Large input, large output and high efficiency.
3. In principle, any fish that can be cultured in a pond can be cultured in a cage.
4. Applying "small-volume and high-density net-cage fish culture technology" in fish ponds can also prevent disease.
5. "Small-volume and high-density net-cage fish culture technology" can also be implemented in smaller water areas, such as mountain ponds, pit ponds, and deep waters of streams. It not only effectively uses water resources, but also has high yields (fish production per cubic meter). 120 kilograms or more), great benefits (more than 200 yuan per cubic meter of profit, as high as 600 yuan).
6. The "seawater deep-water large-cage fish culture technology" has a wider seawater fish culture area, which is a good way for the majority of fishermen to switch to employment and get rich.
Key points of fish culture in cages
1. Choose suitable waters for breeding, and the selected waters should meet the ecological and growth requirements of the fish to be cultivated.
2. Design, manufacture and set up net cages according to technical requirements.
3. Choose suitable farmed fish, determine the stocking specifications, stocking time, stocking amount, and stocking methods and methods.
4. Design, produce or purchase special artificial compound pellet feeds for the species to be bred.
5. Do a good job in daily feeding management, such as feed feeding, water quality monitoring, disease prevention, inspection and maintenance of cage facilities, etc.
