Artificial culture snail technology

Snail is thick, delicate, delicate, fresh and delicious. It is called therapeutic food and snails are effective for kidney fire, ascites, edema, edema, and urination. Artificial farmed snails have less investment, simple methods and high benefits. The breeding techniques are introduced as follows:

First, choose a good variety of screw species can be collected in rice fields, ponds, ditches. The snails should be selected for light-colored snails, thin shells, large shells, no broken ear shells, and high-quality snails. Female snails are large and round. The antennae on the right and left sides of the head are equal in size and extend forward. The male snails are small and long. The right tentacles of the head are thicker and shorter than the left tentacles, and the ends are curved inwards rightward. The curved part is the genitalia, male and female screw species. The proportion is raised with 8:2.

Second, the breeding grounds can be set up to build a single pool, but also can use paddy fields, ditches, ponds, aquaculture, but also polyculture. The single-cultivated snail pond is located in a place where drainage is convenient and no waste water is polluted. Pool width 1.5 meters, water depth 35-45 cm, unlimited length. The bank is built with a dike about 20 cm above the water surface. The pool opens and exits at the opposite corners, and it is designed to prevent escape. Artificially-built fish must also be covered with a certain thickness of silt layer. The surface of the pond should be cultured with aquatic plants such as algae, water lettuce, and red peony for edible snails, shade shelter, summer shelter and habitat.

Third, the good reproductive period for laying and breeding of snails is from April to October, the optimum growth temperature is 20°C-27°C. Fertilized eggs develop into snails in females and female snails each time. Thirty ones can produce more than 150 a year, and can feed 2-3 weeks after delivery. Artificially raise the pool, place 100-150 snails per square meter, and place 15-25 square meters per square meter in natural waters. Snails are very miscellaneous and can feed green vegetables, bean cakes, rice bran, red clams, insects, fish and shrimp, as well as animal organs and waste. Should first soak the solid bait, fish, shrimp, animal viscera crushed, and then use rice bran or bean cake, wheat bran mixed and dispersed after feeding. Feeding once a day at 8 and 9 AM, the daily feeding amount is 1%-3% of the snail's body weight and increases or decreases with weight gain and food intake. For more fertile rice paddies and mollusc polyculture pools, there is a wealth of natural food, but also less or no feeding.

Fourth, to strengthen the management of snails in the water is less than 1.5 mg per liter or when the water temperature exceeds 40 °C will die. In order to promote the rapid growth of snails, in addition to planting aquatic plants in advance in the breeding ponds during the spring season, snails in the high-temperature season during which the snails are actively eating, in order to reduce the water temperature, they should use live water irrigation ponds in semi-fluid water ways. Increase dissolved oxygen. For the performance of calcium deficiency spillage after shrinking the snail lice, fish meal, shell powder, etc. should be added to the feed. Slug is trapped in the shell for lack of food, should increase feeding. It is impossible to raise omnivorous and carnivorous meat, such as fish and squid, in the breeding pond. It is forbidden to inject pesticides in Yangluotian or sources of pesticides.
