Variety Name: Wrinkle Pan-Board Commonly known as: Cassia genus Species: Haliotis Hatiotis disws hannai Ino I. Abalone Overview 1. Biological characteristics Abalone is widely distributed, while Haliotis discus hannai is mainly produced in Huang Bohai is an abalone with a relatively high economic value. Its output is also relatively large, accounting for about 70% of the total output of abalone. The whelk abalone shells are large and thick, with three layers of spirals, sutures and blunt shells. The shell edge has a row of protrusions, with 4-5 openings at the ends, and is in the shape of a tube. There is a groove parallel to the protrusions on the outside of the protrusions. Dark greenish brown shell, growth pattern is obvious, no large pleated shells and silvery white. Bao Ying’s life is inhabited by surrounding seaweeds, with clear water quality, smooth water circulation, and caves, and caves. It grows into variegated animals. Bao is a variegated animal. The food department is mainly composed of brown algae and eats green algae and red. Algae, diatoms, seed plants, and lower animals and plants. The color of the shell is usually closely related to the food it eats. 2. Economic traits Abalone is listed as the first of eight treasures. Its taste is delicious, tender and delicious, and it is rich in nutrients. It is analyzed by dry products, including protein 40%, liver sugar 33.7%, fat 0.9%, vitamins and other trace elements. In addition to fresh meat, Bao meat can also be made into a collection of dry products and various types of canned food. Baocha, also known as Shi Ju Ming, is a multicolored Guang Yan nacre, which is a good raw material for fine decorations and shell carvings. What's more important is its medicinal value. The pharmacological effects of abalone can help the liver to clear away heat, nourishing yin and strengthening the yang, while abalone can reduce blood pressure. Bowenin I and Baolingsu II contained in abalone can strongly inhibit cancer. The role of cell growth. 3. Status Quo of aquaculture Due to its clear habitat, clear water quality, abundant algae, and the habit of water flowing through the caves, abalone is distributed in the southern boundary of the Huangpu Sea in the south of Lianyungang. Since the water depth of the city is not suitable for its growth, the existing abalone breeding method adopts aquaculture, that is, artificially purifying seawater, utilizing the characteristics of the constant temperature of the tunnel, intensive cultivation, and its main breeding site is mainly Shuidao Village of Liandao Town. 4. Economic analysis Abalone farming needs high-input, high-yield, and high-efficiency aquaculture projects. It has a long breeding cycle and high technical requirements. As a result, investment risk is high, but its high profit is still deeply appealing to breeding units. An example of aquaculture of 1 million abalones is used in the tunnels: 100 million head farms will raise abalone farms. The total investment is about 10 million yuan. Among them, the assets investment is more than 6.5 million yuan, the production cost is more than 3.6 million yuan, and the survival rate of breeding can reach 90%. Sales price of 400,000 yuan / T, then the sales income of up to 13.68 million yuan, total profits and taxes can be achieved more than 870 million, sales profit and tax rate of 63.35%, investment recovery period of 2.56 years. In summary, it can be seen that the use of pits to cultivate abalone, if the technical measures are appropriate, the effective control of disease, its prospects are still broad.
