Abalone is a valuable marine product. In recent years, artificial abalone cultivation in China has developed rapidly. The main breeding models include factory culture, floating raft breeding, and sowing. The caisson culture mode is a new type of abalone breeding mode recently emerged. In 1999, we conducted caisson tests at Weizhou Island in Beihai City and achieved good results. First, the characteristics of caisson Bao holding 1. Investment in small-scale farming may vary, small-scale breeding investment 1-20,000 yuan can be operated for general farmers. 2. Low cost Compared with factory-made abalone, etc., the cost of raising caisson in the caisson is very low. 3. Short period from seeding to harvest only 5-6 months. 4. Strong wind and wave resistance The cement caisson is very strong and can be installed on the beach to resist wind and waves. 5. Low risk From a practical point of view, as long as the survival rate reaches 40%, even if the price drops to 80--100 yuan per kilogram (current price is about 170), it can still maintain the cost. Second, the eco-characteristics of abalone 1. abalone-abalone abalone like to eat Gizzard, Sargassum, wakame, etc., these types of seaweed are very rich in the coastal areas of our region. The 2 cm seedlings of abalone were cultured to 4 cm and the bait coefficient was approximately 25. 2. The juvenile abalone grows rapidly. From 2 cm seedlings to 5 cm commercial abalone, it usually takes only 5-6 months. After the abalone grows to 6 cm, the growth rate is significantly reduced. The peak of its growth is between September and December of each year. 3. Living environment Abalone likes to live in places where water is clear and flowing. Tests have shown that the abundance of abalone in the calm and turbid sea area is extremely high. The abundance of abalone life is relatively high. When the specific gravity of seawater is lower than 1.015 or higher than 1.026, the growth is inhibited and there is even a risk of death. The optimum proportion is 1.020--1.025, and the suitable temperature range is 10-33. C. Third, caisson design Caisson is reinforced concrete structure. The profile height is 60 centimeters, the outer diameter is 105 centimeters, and the inner diameter is 100 centimeters. The caisson consists of five parts: (1) The caisson body, which is the main part of the caisson. There are seven circular holes with a diameter of 16 cm at the bottom, and eight circular holes with a diameter of 4 cm are also provided at the bottom of the side of the box to facilitate the passage of water. (2) The caisson lid, also a concrete structure, makes the caisson a closed environment with a feeding opening in the center of the lid and a diameter of 30 cm. (3) Sets of nets, made of 0.3--0.5 cm mesh polyethylene mesh, placed on the inner wall of the caisson to prevent abalone from escaping. (4) Iron wire bracket, composed of 8# iron wire, supporting the net. (5) The abalone inhabits the platform and the concrete structure is placed inside the caisson cover net for the abalone to inhabit. Each caisson can be stocked with 600 abalones. 4. Caisson placement Casings shall be placed in the sea one month prior to the seedlings. In addition to satisfying the ecological requirements of abalone, the caisson settlement must also have the following points: smooth flow, gravel bottoms, small wind waves, and a 20- to 30-cm box must be exposed after ebb tide to facilitate aquaculture management. Fifth, seedlings to buy and transport the abalone seedlings must be more than 2 cm in size. Requires uniform specifications, no nicks, vibrant colors, and fresh, visible signs of shell edge growth. This kind of seedling has good vigor and is suitable for breeding. Seedlings are generally purchased during March-April, and are also available from August to October. Abalone is very resistant to transport, transport time is less than 2 hours, can be dry dew transport, longer than 2 hours, can be used live transport vehicles. Sixth, daily management Abalone can be fed on the next day to feed the bait and enter the normal management stage. In this stage, every 12-15 days, it is necessary to feed Sargassum or G. argentea once, and the feeding amount of each caisson is 5-6 kg at each time. During the peak of growth, it is necessary to feed 8-9 kg each time. . The cages should be thoroughly cleaned once a month, mainly to clean up the sand, leftovers, shrimp, and small crabs inside the box. When cleaning, avoid abalone exposure time is too long, bruises or dead. During the entire cultivation period, abalone activity, sea salinity, pH, and water temperature were recorded every day.
