Rice field breeding device for field snails and use method of rice field breeding device

Abstract

The invention discloses a rice field breeding device for field snails and a using method of the rice field breeding device. The rice field breeding device comprises a spawning groove, a spawning groove attachment plate, a bottom net, an attachment device and an anti-escape cover, wherein the spawning groove with the small bottom and the large top opening is defined by the spawning groove attachment plate, a net piece is fixed to the side wall of the spawning groove attachment plate, the bottom net is fixedly installed at the bottom of the spawning groove, the attachment device is installed in the spawning groove, the bottom of the attachment device is fixedly connected with the bottom net, and the anti-escape cover is arranged at the top of the spawning groove. The problems that in the prior art, due to the fact that field snails are difficult to breed and separate, the survival rate of the field snails is low, batch breeding cannot be conducted, dead snail shells of the field snails are difficult to clean and decompose due to mixed breeding of young field snails and breeding field snails, and consequently the production efficiency of the whole field snail breeding industry is low, and the industry development is slow are solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of aquaculture, and in particular to a snail paddy field breeding device and a method for using the same. Background technique [0002] In the natural environment, adult snails in paddy fields like to attach to the edge of the field or fields rich in bait and humus, and do not have the ability to swim and do not like to move; while young snails have swimming ability, like to move, and like to eat small algae. Field snails have a short lifespan and need to be sexually mature in one year. Female snails have a lifespan of 3 years and male snails 3-5 years. Parental snail breeding is spawning in batches. The spawning time can be from April to October. The fertilized eggs are produced after they develop into young snails in the female snail nursery. Each litter can produce 20-50 eggs and can produce 80-180 eggs a year. egg. After the snails are born, the snails will actively forage for...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the present invention provides a snail paddy field breeding device and its use method to solve the problem of low survival rate of snails and seed snails in the prior art due to the difficulty in breeding and separation of snails and the inability to carry out batches. It is difficult to clean and decompose dead snail shells after secondary breeding and planting snails, which leads to low production efficiency and slow industrial development of the entire snail farming industry.
