Embodiment 1

[0033] A breeding method for thick-shell snails, comprising the following steps:

[0034] a. Construction of snail ponds: choose a place with sufficient water sources and fresh and clean water to build snail ponds, and set up anti-escape walls or fences around the snail ponds. The water depth of the snail ponds is within 80cm, the bottom of the pond is covered with silt, and straw is piled in the pond;

[0035] The water body in the snail pond is disinfected before breeding, and the water body is disinfected every 20 days during the breeding process.

[0036] b. Selection and stocking of parents: choose stone snails as the male parent and field snail as the female parent, and put them into the snail pool with a water temperature of 18°C ​​at a ratio of 1:1, feed them with high-protein feed, and let the snails hybridize and reproduce by themselves. ;

[0037] Among them, the snail age of the stone snail is 8 months old and the body weight is 14g / piece; the snail age of the fie...

Abstract

The invention provides a method for breeding thick-shell river snails, and particularly relates to the technical field of aquaculture. The method comprises the following steps of: a, building a riversnail pool, specifically, a place with sufficient water source and fresh and clean water quality is selected to build the river snail pool; b, selecting and rearing river snail parents, specifically,a stone snail is chosen as a male parent and a river snail is chosen as a female parent; c, breeding young river snails, specifically, the individual young river snails with the shell thickness of 60-80 mm are selected from a first generation produced by the female parents, and hybridization is carried out according to the ratio of female to male of 4-5: 1 to produce a second generation of the young river snails; d, rearing and screening the young river snails, specifically, dead river snails and the river snails with holes at the tails of the second generation of the young river snails are weeded out to obtain the thick-shell river snails; and e, breeding the thick-shell river snails, specifically, the thick-shell river snails are raised to 8-12 months of age and then the thick-shell river snails for the breeding of a next generation of the river snails are reserved according to the ratio of female to male of 4-5: 1. According to the method, the bred thick-shell river snails have theadvantages of being large in body size, thick in shell, convenient to transport, crisp in mouth feeling, fresh and sweet in taste, high in survival rate and stable in quality; and the breeding processof the method is simple and feasible, the elimination rate is low, the management is convenient, and easy to be popularized.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of aquaculture, in particular to a method for breeding thick-shelled snails. [0003] 【Background technique】 [0004] Escargot is a kind of freshwater snail produced in China. It has the effect of clearing away heat and reducing fire. In recent years, with the natural production of snails decreasing day by day, the market of snails has been optimistic. Artificial breeding in Guangxi, Guangdong, Fujian and other regions in the south of my country has developed rapidly, and many farmers have taken the cultivation of snails as a way to start a business and vigorously developed it. [0005] At present, in the cultivation of snails, they are harvested from the wild and collected from the market as seed snails for breeding. The traits of the bred snails are consistent with those of the seed snails, and they have the defect of thin and fragile shells, which are not suitable for transportation in different ...
