Like Fusiliers, snails are also good feed for snappers.

(1) The varieties of snails distributed in China include Chinese round snail, Chinese round snail, bloated round snail, long spiral round snail and Ussuri snail. The following is the more widely distributed Chinese round snail. (2) the snail's habits of the snail like to inhabit in the humus-rich bottom mud of the water environment, such as lush lakes, ponds and marshes, field puddles or slow-flowing gullies and other bodies of water, often microbes and humus in the soil and phytoplankton in the water, young aquatic plants, moss and so on as a food. It also likes to eat artificial feed, such as fruits and vegetables, vegetable leaves, rice bran, wheat bran, soybean meal (cake) and various animal scraps. Snail cold and fear of heat, the appropriate temperature of its life for 20 ~ 28 ℃, the water temperature is lower than 10 ℃ or higher than 30 ℃ that is to stop feeding, drilling into the soil, and into the grass to avoid the cold and heat. When the water temperature exceeds 40℃, the snail will be scalded to death. (3) The reproductive habits of the snail is dioecious. The method of distinguishing between male and female snails is mainly based on the morphology of their right antennae. The right antenna of the male snail is curved to the right (the curved part is the male genitalia), in addition, the female snail is large and round, and the male snail is small and long. The snail is an ovoviviparous animal with a unique reproductive pattern, in which the embryonic development of the snail and the development of the young snail are completed within the mother's body. From the fertilized egg to the baby snail, it takes about one year of gestation in the mother's body. The snails lay eggs in batches and start breeding from March to April every year. While producing young, the female and male parents will mate and fertilize the snails, and at the same time, the snails that will be produced the following year will be conceived in the mother's body. Each female snail produces about 100 to 150 young snails throughout the year. (4) snail pond conditions culture snail pond, single pool area of 100 meters 2 is appropriate. The pond is rectangular, with a depth of 80 centimeters and a water depth of 50 centimeters. The bottom of the pond should maintain a thickness of 10 to 15 centimeters of substrate. The pond is surrounded by some long vines and vegetables to shade, and the water is arranged with bamboo tails, tree branches or stones, grass, etc. for snails to hide and live. (5) snail breeding water requirements snail like clean slightly fertile water, water quality requirements for dissolved oxygen, pH7 or so, the water body can not have pesticides, fertilizers and industrial pollution. Snail adaptability, less disease, as long as the avoidance of a large number of poisonous, many flat rivers and canals in rural areas, beaches, pits, rice paddies, ponds and other ordinary water bodies can be stocked. If you dig a special pool to raise can choose a convenient water source, keep the water body in a good place, breeding the water surface can be cultivated a small amount of redbuds and water lilies and so on. (6) species of snails stocking species of snails put before 10 days, according to the dosage of 50 to 100 kg per acre of the whole pool of quicklime, to remove the wild fish and shrimp and other miscellaneous snails, 3 to 4 days after the water in the body of the pile of organic fertilizers and propagation of bait organisms for snails to feed on. Seed snail stocking is best accomplished in the pre-breeding period of the snail. The source of seed snails: one is the field collection, the second is the market collection. Choose fresh snails that are light brown in color, with thin and intact shells, and rounded bodies with blunt tops. General natural rough water body per square meter put seed snails 0.1 ~ 0.5 kg, intensive pool can increase the amount of seed 2 ~ 3 times. Cultivation of snails can be stocked alone, can also be part of silver and bighead carp species or take snails, loach mixed culture. (7) Careful feeding In the case of high-density artificial intensive culture, artificial baiting must be done carefully. Snails do not have high nutritional requirements, simply use rice bran, wheat bran, soybean meal to 60%, 25% and 15% of the proportion of the snail's top feed. According to the snail eating situation and climate, in the growth of suitable temperature (i.e., 20 ~ 28 ℃), snail appetite, can be fed every 2 days, each feeding amount of 2% to 3% of body weight. When the water temperature is in the range of 15～20℃ and 28～30℃, feed twice a week and give about 1% each time. When the temperature is lower than 15℃ or higher than 30℃, less or no feeding. (8) Daily management strictly prohibit the inflow of water contaminated by pesticides and fertilizers; prevent the invasion of ducks, snakes, rats, birds and other hostile pests; and remove weeds and grass roots from the water in time. Normally take the form of micro-flow water, keep the water level at about 30 centimeters. Increase the water flow in the high temperature season to control the water temperature rise and ensure that the water body has sufficient dissolved oxygen. Cold weather snails into the mud hibernation, at this time, change the water 1 to 2 times a week, and to the water body to sprinkle some chopped straw, in order to facilitate the snail overwintering. (9) snail fishing when the snail grows to 1 kg 80 or so, can be harvested to feed turtles. When harvesting snails, you can take the method of catching big and keeping small, selectively catching adult snails, keeping young snails and paying attention to keeping some female snails, so as to achieve natural replenishment, and then do not need to put the seed snails again. According to its habits, in the summer and fall high temperature season, choose early morning, night in the bank or water body rotating bamboo branches, grass handle picking; winter and spring is to choose a sunny day at noon picking. In addition, you can also use the pool to touch and catch or drainage dry pool picking methods such as harvesting snails. It is best to feed the snails fresh on the same day and not leave them for too long.
