Device for collecting young field snails in rice field and using method of device

Abstract

The invention discloses a device for collecting young field snails in a rice field and a using method of the device. The device for collecting the young field snails in the rice field comprises a young field snail collecting groove, an attaching device and a groove bottom, wherein the young field snail collecting groove is in an inverted circular truncated cone shape with the small bottom and the large top, the top of the young field snail collecting groove is open, the side wall of the young field snail collecting groove is a first mesh piece with square mesh holes, the attaching device is installed in the young field snail collecting groove, the groove bottom is installed at the bottom of the young field snail collecting groove, and a second mesh is laid at the groove bottom. The device solves the problems that in the prior art, due to the fact that young field snail collection is difficult and mainly depends on wild breeding field snail stocking and multi-batch young field snail collection, the field snails in the rice field are affected by external factors such as bait richness, large-specification snail food grabbing stress and insufficient growth environment, young field snail supply is difficult, and field snail industry development is slow.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of aquaculture, in particular to a device for collecting seedlings in a snail paddy field and a method for using the same. Background technique [0002] In the natural environment, the snails in the paddy field like to attach to the fields with rich bait and corrosive substances, or attach to aquatic plants for food. The female snails lay eggs in batches, and the spawning time is from April to October every year. The female snail nursery develops into young snails and produces 20-50 snails per litter, which can produce more than 100-150 snails a year. Generally, it is difficult to separate the female snail from the young snail. The young snail has swimming ability and quick movements at birth. As it grows and develops, it gradually loses its swimming ability and slows down its movements. The snail likes the shade, and also likes to forage on the water surface, or on the aquatic pla...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the present invention provides a kind of snail paddy field seedling collection device and its use method, to solve the problem of snails in paddy fields caused by the difficulties in collecting snail seedlings in the prior art mainly relying on wild snail species stocking and multi-batch collection of snails. Affected by external factors such as the abundance of bait, the stress of large-scale snails, and the lack of growth environment, it is difficult to supply seedlings for snails and the development of the snail industry is slow.
