The industrial seedling raising method of pipe horn snails

Abstract

The invention discloses an industrialized breeding method for hemifusus tuba gmelin. The method comprises the following steps: collecting healthy, strong, fatty, relatively large and relatively heavy parent hemifusus tuba gmelin, temporarily rearing the parent hemifusus tuba gmelin in a round net bag and a plastic basket for later egg laying, naturally propagating to obtain egg pods, putting the egg pods into a plastic sieve basket floating in a hatching pond, and hatching for 30-60 days under the condition that the water temperature, the salt content, the pH value and the egg pod density are proper, wherein the hatching process is carried out in a dark place for first 20 days, the hatching pond is directly irradiated by sunlight for 2-3 days, and the hatching pond is kept out of sun, so that the hatching rate can be increased and is about 90% and the death rate of hatched young hemifusus tuba gmelin is reduced; moving the young hemifusus tuba gmelin into a breeding pond with benthic diatoms covering the bottom and walls, and breeding for more than 20 days under the condition that the water temperature, the salt content, the pH value and the egg pod density are proper, shelled sinonovacula constricta meat is fed, water is changed and the pond is overturned, so as to obtain hemifusus tuba gmelin eggs, wherein the breeding rate reaches more than 80%. Therefore, a large amount of the young hemifusus tuba gmelin can be bred and put in a suitable place to breed, and hemifusus tuba gmelin resources can be recovered.

Description

technical field [0001] The invention relates to the breeding of picornis snails, in particular to an industrial seedling raising method of picornis snails. Background technique [0002] Pipe angle screw ( Hemifusus tuba Gmelin ) belongs to the mollusca (Mollusca), gastropoda (Gastropoda), neogastropoda (Neogastropoda), helmet snail family (Galeodidae), horned snail ( Hemifusus ), which are economical gastropods in shallow seas, are mainly distributed in soft mud and sandy seabeds of 11-40m along the coasts of Zhejiang, Fujian, Guangxi, Guangdong and Hainan provinces in China. Efficacy, and the glycoprotein in the muscle has significant anti-cancer activity, it is a rare seafood. In recent years, due to the pollution of sea areas and over-harvesting by humans, the resources of snails are becoming increasingly depleted. At present, the research on snails mainly focuses on natural reproduction and artificial maturation, and large-scale industrial seedling breeding has not ...
