1. Water selection. Should choose reservoirs, rivers and other larger bodies of water. The cages are set up to shelter from the wind, have clean water, have small water flows, depths of 2.5 to 3 meters, and 6 meters offshore. The cage spacing is 3.5 meters.
2. Fish feeding. Mainly grass carp, with appropriate amounts of blue, oysters, oysters, clams, squid. Each cage puts 0.25 to 0.3 kg grass carp 600 to 800 tails, and fish 20 to 30 tails (carp feeding should not exceed 10 tails). Fish species must be robust, disease-free, non-injury, and uniform in size. Before stocking, they were sterilized with a concentration of 3% to 4% saline for 5 to 15 minutes, and a grass carp hemorrhagic disease vaccine was injected.
3. Feed feeding. It is mainly fed with ryegrass and Sudan grass. If the water temperature is lower after the fish is put in the box, you should feed the cooked sweet potato mixed rice bran or wheat bran, or feed the fish grain bait to ensure the growth. When the water temperature is normal, it is necessary to ensure adequate supply of grass every day, and regularly feed a small amount of rice bran, wheat bran, bean cake and so on. When the fodder is insufficient, fresh leaves can also be fed. The feed must be scheduled (8 to 9 am, 2 to 3 pm), quantitative (generally 1.2 to 1.5 times the total weight), and positioning (fixed in the feeding frame).
4. Daily management. Before and after the fish is placed under the box, check the cage for holes to prevent fish species from fleeing. Frequently remove attachments on the net to avoid clogging. Before the feeding, the remaining bait will be cleared out of the box. The newly cast forage should be fully wetted and spread evenly over the surface of the water. With the increase of feed, the feeding range will increase. In the hot season, feed should be taken in the morning and in the evening, and a arbor should be placed on the feeding box to avoid burning of hot hay.
5. Fish disease control. In the summer and autumn fish disease epidemic season, periodical full-bore sprinkling of bleaching liquid and lime slurry shall be performed periodically. The bamboo powder or cloth bag shall be used alternately with strong chlorine, bleaching powder, copper sulphate, trichlorfon, etc. and be hung around the cage to prevent fish. disease. In the event of a fish disease, baits can be taken orally.
