Breeding method of limnaea peregra

Abstract

The invention discloses a breeding method of limnaea peregra. The breeding method comprises the following steps of (1), base construction; (2), breeding of seed limnaea peregra; (3), breeding management. According to the breeding method of the limnaea peregra, the defects that existing limnaea peregra is low in breeding survival rate, low in breeding density, small in yield and low in quality areovercome.

Description

technical field [0001] The invention relates to the technical field of breeding methods, in particular to a method for breeding snails. Background technique [0002] Snails are a general term for molluscs of the gastropod family Snail family, hermaphrodites. With a spiral shell, the spiral part is generally low. The shape is as small as a vertebra, and the shell is thin, dark and translucent. The spiral part is pointed, the body spiral layer is quite large, the shell mouth is wide, and there is no shell; the body is soft and can be retracted into the shell. The head has 1 pair of retractable antennae, and there are eyes at the base of the inner side of the antennae; the ventral part of the head has mouthparts, which are short and enlarged. There is a genital opening on the right front of the body, and the female and male pores are separated. It has lungs for breathing, but because it lives in water, part of its mantle extends into secondary gills. It hibernates in the s...
