Several knowledge points of snail farming

[ Agricultural Products Network] We have selected several knowledge points for snail breeding for industry reference.

The snail breeding site should choose a place with sufficient water source, good water quality, humus soil and convenient transportation. It is best to have live water or running water.

Aquaculture pond construction standards. The size of the screw pool is generally 1.5-1.6 meters wide and 10-15 meters in length. The terrain can also be used. The pool is surrounded by squats, and the height is about 50 cm. The water inlets are opened at both ends of the pool and the barriers are installed to prevent the snails from escaping. At the same time, the aquatic plants such as white peony are planted in the middle of the breeding pond, which not only improves the land yield, but also creates a good ecological environment for the growth of snails.

Snail stocking density, per square meter of breeding snails general stocking 100-120, while the summer polyculture per square meter body bighead nobilis cultured for about five fish species. The snail stocking time is generally in March.

Tianluo is a gastropod mollusk. It likes to live in the waters with warm winter and cool summer, soft bottom, rich bait and fresh water. It is especially fond of clustering in micro-flowing water. The snails are miscellaneous, mainly eating tender stems and leaves, organic debris, etc., and the snails prefer nighttime activities and feeding. The optimum temperature for breeding is 20-27 °C.

The snail reproduction law. When the water temperature rises to 15 °C in the late spring and early summer, the snail climbs out of the wintering hole and feeds on the bottom of the water. Reproduction begins in April, and July-August is the season of snail breeding. Female snails of 1 to 2 years old can produce 20 to 30 litters, and female snails of 4 or older age can produce 40 to 50 litters. After being born, the snail grows rapidly and develops sexual maturity in one year. The annual season is from April to September.

What does snail eat? Like to inhabit the humus-rich water environment of the sediment, such as watery lakes, ponds, fields, or slow-flowing rivers and other water bodies, often with microbes and humus in the soil and phytoplankton, young aquatic plants, moss in the water. Waiting for food, but also eating artificial feed , such as fruits and vegetables, vegetable leaves, rice bran, wheat bran, soy flour (cake) and various animal wastes. The snail is cold-resistant and phobia. The suitable temperature for its life is 20-28 °C. When the water temperature is lower than 10 °C or higher than 30 °C, it stops eating, drilling into the soil, and avoiding the cold in the grass. When the water temperature exceeds 40 ° C, the snail is burned to death. In the dry season, it completely shrinks the soft body into the shell, so as to reduce the evaporation of water; in the cold winter, it will penetrate into the soil and stay in the hibernation state. In the spring warm period, when the temperature rises to suit its activities, the head and feet will extend out of the shell to crawl. It is most suitable for growth temperatures of 20 to 26 degrees, at which time it eats the most vigorous and grows fastest. When the water temperature rises to 30 degrees, it stops eating. It is not resistant to high temperatures, but it is very cold-resistant, and it will dig and reproduce in the cold season.

The snail is dioecious and has a male and female. The method of distinguishing between female and male snails is mainly based on the shape of the right antennae. The right antennae of the male snail is bent 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.
