1 Undersea culture: Place young abalone about 2 cm in a breeding cage, feed 10-30% of the bait, seal it and place it on the seabed; you can also place the young abalone directly in a place with good natural conditions Sea area (proliferation). 2) Raft culture: place young abalone in an abalone culture cage, and then fix it on a floating cage for culture. Feed regularly, remove fecal impurities and residual bait, wash away sludge, and dredge water flow. 3) Pond culture: In areas where conditions are favorable, ponds can be built on land, and flowing water and inflatable culture can be used. 4) Factory farming: A farming method that builds abalone breeding rooms and controls water temperature by building cooling and heating systems. 5) Tunnel farming: Intensive farming (which can be called a type of factory farming) takes advantage of the natural conditions of constant temperature in the tunnel itself and treats water quality. At present, our city mainly uses tunnel farming and bottom sowing in the waters of the first three islands. There are two methods of proliferation. Feeding is required for feeding young abalone, and the quality of the feed is directly related to the growth rate of the abalone. Generally, abalone cannot eat large algae at about 3 mm, and mainly relies on adherent diatoms for food. There is no need to feed at this time. After growing to 5-6 mm, they begin to feed on delicate enteromorpha and other algae. As the individual grows, the number and quantity of feeding in natural sea areas and breeding depends on the season and the water temperature in summer. High, seaweed is easy to rot, the fronds will rot and sink to the bottom, ammonia nitrogen in the water will increase, and dissolved oxygen will decrease, which can easily cause the deterioration of the culture environment and affect the normal activities of abalone. Therefore, feed once every 2-3 days at this time, and the amount of feed should be The amount should be less, as long as it can be eaten. Autumn is the season when abalone grows faster, so it needs to be fed with enough fresh food every 4-5 days. In winter, the water temperature is low, and the food intake of abalone is small, and fresh algae are soaked. It will not rot in the water for 7-8 days, so feeding can be done every 8-10 days in winter. Note that each feeding should be done after removing the bait residue and abalone excrement and replacing it with fresh seawater. , in the absence of fresh seaweed, dried algae can be soaked and fed as bait, and the algae feeding effect is better to be mixed. Among the algae, wakame, kelp, kelp, horsetail, etc. are the ones that abalone prefers to eat. Seaweed has good feed effect and fast growth rate. The test results of seaweed, which is rich in local resources, are not ideal and have a great impact on the digestion of abalone. Artificial feed can also be fed to abalone, and the animal content should be considered when using it. Egg whites are perishable when soaked in water, so the feeding time for factory-cultured abalone or tunnel-cultured abalone is basically the same as above. The difference is that the water temperature and room temperature of factory-cultured or tunnel-cultured abalone are relatively constant, so the feeding time is shortened accordingly. There is a difference in baiting time
