Mud snails, also known as spit iron, wheat snail, and soft snail, are marine molluscs. The shells are ovoid, thin and brittle. The shells are about 40 mm long and about 12 mm to 15 mm wide. It is distributed on both the north and south coasts of China and is a fine shellfish variety along the beach.
Bullacta exarata is a typical intertidal zone benthic animal, living in muddy or muddy tidal flats in the mid-low tide area, crawling on the surface of the mudflat after ebb tide. When the rain is cloudy or the weather is cold, use a head plate and dig a hole to hide in the surface layer of the sediment from 1 cm to 3 cm. It is not easy to be discovered. After sunrise, it climbs out to feed. The benthic algae, organic debris, and no Vertebrate eggs, larvae, and small crustaceans are the main foods. It has strong adaptability, and it can survive in severe cold winter (1.5°C) and hot summer (33°C), but the optimum growth water temperature is 15°C～30°C. There is no low temperature problem in the south of China, but it is also necessary to prevent High temperature, if the water temperature exceeds 33°C, the survival rate is only 60% within 48 hours. After being raised for one year, the mud snails can reach sexual maturity. From May to June each year, it is a breeding season. Usually spawning is performed in the evening or in the middle of the night. Bullacta exarata grows faster. According to reports, general stocking is 5 months to 6 months. Specimens of 100 to 150 grains per kilogram can be captured and listed, and small and small can be captured. The most full of meat.
Bullacta exarata is one of the precious marine products. Its body is hypertrophic, the meat is refreshing, the fragrance is clear, the nutrition is rich, and it has the therapeutic effects of supplementing the liver, kidney, essence, eyes and eyes and body fluid. Its variety of food, fresh food, porridge, fried snail meat is fresh and delicious, processed salted wine stained mud screw cans, wine stains mud snail meat, in addition to domestic best-selling, but also exported to Hong Kong, Macao, Taiwan and Southeast Asia area. It was also learned that the meat was processed and sold well in European and American markets after being frozen. As mud snails are becoming more and more popular, the market demand for mud snails is increasing day by day. It is reported that Shanghai's annual sales volume has exceeded 1,000 tons, and the annual growth rate of 30%, Guangzhou, Shenzhen and other large and medium-sized cities are expensive, and often out of stock. Due to the limited amount of wild resources, artificial breeding has not developed very well. As a result, the supply of scarce resources has steadily increased. For instance, the price of mud mud in Guangzhou has increased from 110 to 116 yuan per kilogram in August to November of last year. Yuan ~ 150 yuan. Therefore, experts believe that mud snails raw omnivorous, strong adaptability, and actively develop aquaculture promising.
