Embodiment 1

[0039] This embodiment discloses a snail paddy field breeding device, the snail paddy field breeding device includes: spawning tank 1, spawning tank attachment plate, bottom net 2, attachment device 3 and escape prevention cover 4, the spawning tank is attached The plate surrounds and forms a spawning tank 1 with a small bottom and a large opening at the top. A mesh is fixed on the side wall of the attachment plate of the spawning tank, and the bottom net 2 is fixedly installed on the bottom of the spawning tank 1. The attachment device 3 Installed in the spawning tank 1, the bottom of the attachment device 3 is fixedly connected with the bottom net 2, and the escape prevention cover 4 is arranged on the top of the spawning tank 1.

[0040] The length and width of the bottom of the spawning tank 1 is 180cm * 60cm, and the length and width of the top are 240cm * 100cm. The bottom is small and the top is large, which can reduce the floor space at the bottom and increase the shadi...

Embodiment 2

[0048] This embodiment discloses a method for using a snail paddy field propagation device, the method is:

[0049] Soak the spawning tank and attachment device 3 in potassium permanganate solution for 10-20 minutes to fully sterilize;

[0050] After cleaning, put it into the paddy field for 3-7 days, place the snails after the spawning tank and attachment device 3 are covered with biofilm and algae;

[0051] The seed snails lay eggs naturally in the breeding device, observe the spawning situation and the situation of the young snails swimming out of the spawning tank, and feed the seed snails feed and green material for 2-3 days, which can be properly sprinkled in the paddy field outside the spawning tank algae, to lure larvae to swim out;

[0052] When the seed snails produce enough young snails, the whole spawning device is lifted, and the young snails are rinsed into the paddy field, and the spawning device is placed in another paddy field.

[0053] Adopting this method ...

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...
