Embodiment 1

[0041] Such as figure 1 , image 3 , Figure 4 As shown, a large-scale device for establishing a family of pear-shaped snails includes a screw 1, a support surface 2, and a cage 3. The screw 1 is used as a column to support the entire device, and the support surface 2 is socketed with the screw 1 and distributed on the screw 1. The upper and lower ends of the screw 1 are fixed, the upper and lower parts of the snail cage 3 are detachably connected with each other, and the snail cages 3 are superimposed on each other and placed between the adjacent support surfaces 2. The upper end of each snail cage 3 combination and the lower ends are against the adjacent supporting surface 2 respectively.

[0042] The supporting surface 2 is movably connected with the screw rod 1, and the supporting surface 2 moves up and down along the axial direction of the screw rod 1.

[0043] The material of the screw 1 is stainless steel, the length is 1500 mm, and the diameter is 5 mm.

Abstract

The invention relates to a device and method for establishing a bellamya purificata family on a large scale. The device comprises bellamya purificata climbing rods, supporting surfaces and bellamya purificata cages; and the bellamya purificata climbing rods are used as stand columns to support the whole device, supporting surfaces are connected with the bellamya purificata climbing rods in a sleeving manner, the upper and lower ends of the bellamya purificata climbing rods are fixed, the bellamya purificata cages are mutually overlapped and placed between adjacent supporting surfaces, and theupper and lower ends of each bellamya purificata cage combination separately abut against the adjacent supporting surfaces. According to needs, each group of device is equipped with M bellamya purificata cages, N groups of devices are arranged to construct M*N families, and offsprings of each female bellamya purificata are raised in one same bellamya purificata cage. According to the device and method disclosed by the invention, a plurality of bellamya purificata families can simultaneously constructed according to needs, the device occupies less land and has a high space utilization rate, young bellamya purificata has a high survival rate and grows well, and the requirements for large-scale establishment of the bellamya purificata family are met; and meanwhile, female individuals and maleindividuals are raised separately, mating frequency of the male individuals is controlled, so that consumption of excellent male individuals is reduced, precious germplasm resources are protected, and the reproductive efficiency and offspring quality of the bellamya purificata are improved.

Description

technical field [0001] The invention relates to the field of genetic breeding of aquatic animals, in particular to a device and method for establishing a large-scale family of piriform snails. Background technique [0002] Pear-shaped ring-shaped snail (Bellamya purificata), commonly known as snail, bean snail, and stone snail, is the largest species of the genus Bellamya purificata. This species is widely distributed throughout the country, with a large output and many uses. It is one of the important baits for aquatic economic animals such as herring, wide-bodied golden leech, Chinese mitten crab and soft-shelled turtle, and some waterfowl. It is also one of the aquatic products that are very popular among residents. One, it has thus received increasing attention. As an important part of the freshwater ecosystem, the piriform snail is both a consumer and a decomposer. It feeds on plankton in the filter-feeding water body and licks organic debris in the environment. It con...
