CATDOLL : CATDOLL: If you want to use silver carp cage farming technology to breed silver carp, what issues should you pay attention to during the actual operation?

Silver carp cage culture is a three-dimensional culture technology that makes full use of reservoir resources. Its advantages are low cost and high efficiency. There is a large profit margin, which is conducive to the improvement of economic benefits. Let me introduce some technical points to you.

First, pay attention to the structure of the cage frame. Most cages are made of polyethylene with a diameter of 1.13mm, a mesh size of 3~5cm, and a cage size of 4m×7m×2m. Use a single-layer frame, and the frame is a bamboo pole with a diameter of about 10cm. Multiple cages are connected together to fix the water tank and avoid drifting.

The layout of the cage will affect the growth rate of catfish. Generally speaking, the cage needs to be placed in a relatively wide water body, the water body should not be too large, the water quality should be good and pollution-free. It needs a reservoir with sufficient sunshine, leeward, sufficient sunshine, high water temperature, sufficient bait, 4-7m water depth and convenient transportation.

November to December or February to March is the best time to stock cages. The water temperature is lower at this time, which is less harmful to fish and has a higher survival rate. The breeding scales are 80g and 350g respectively. If the stock is 80g, there are 450 to 550 fish per box. If the stock is 350g, the number of fish per box is 200 to 250. Disinfect the fish before releasing to prevent them from getting sick and dying in the fish tank.

Good breeding and management are essential for fish farming. The quality of breeding is directly related to the success of breeding. With reasonable feeding and management, silver carp grows rapidly, has low mortality and good benefits. If it is not managed properly, the growth of catfish will slow down, and the morbidity and mortality will be high. Therefore, attention should be paid to cage fish farming and management. If the fish is placed in a new cage, it should be soaked in water 7-10 days in advance to prevent the rough surface of the new cage from injuring the fish. When the cage is placed in the reservoir, a lot of dust will adhere to the cage due to the action of plankton, which will reduce the amount of plankton in the cage and cause insufficient feed for silver carp. Therefore, the cage needs to be cleaned frequently, usually every 15 to 20 days.

During the cage culture process, the cages should be moved according to the actual situation. In order to prevent the cages from being washed away during the flood season, it is necessary to move the cages. Moving the cages can also increase the biological content of erbium in the cages and increase the growth rate of catfish. Although catfish feed on plankton, when the water body is too thin or there are too many nets, it is necessary to increase the biomass of the bait net to provide sufficient bait for silver carp and increase the growth rate of catfish.

The daily management of captive silverfish also needs to be taken seriously. Check the cages frequently, observe the activities of catfish, and find problems in time. The above are the key points of catfish cage farming operation technology for your reference and learning.

The size of the cages should be determined based on the area of ​​the aquaculture waters. The cages can be set in medium to large water environments with relatively slow water flows, such as lakes and the lower reaches of rivers.

It is necessary to pay attention to the water temperature for breeding silver carp, the fish in the reservoir, the fish breeding methods, the fish storage process, and the health of the feed. These are all issues that need to be paid attention to when breeding fish.

During the actual operation, you should pay attention to preparing oxygen generators and disinfectants, ensuring the water quality is clear, and having surplus bait and feed.
