Attachment for improving survival rate of juvenile mytilus coruscuses and using method thereof

Abstract

The invention discloses an attachment for improving the survival rate of juvenile mytilus coruscuses and a using method thereof, and relates to artificial shellfish breeding in the field of aquaculture. The attachment is formed by putting a bamboo fiber-woven mesh into a special pressure cooker, cooking for 1 hour by using tea water, fishing out, and drying in the sunlight, wherein the mesh is 60-mesh, has the width of 60cm and the length of 100cm; pendants with proper weights are hung on the length side of the mesh. The using method of the attachment comprises the following steps: selecting creeping larvae, collecting the growing creeping larvae, attaching and controlling an attachment condition. The attachment improves the attaching survival rate and the attaching density so as to increase the metamorphosis rate of the larvae, reduce the breeding cost of the mytilus coruscuses and promote the development of the breeding industry of the mytilus coruscuses.

Description

technical field [0001] The invention relates to artificial culture of shellfish in the field of aquaculture, in particular to an attachment and a use method for improving the survival rate of juvenile mussel mussels. Background technique [0002] Mussels belong to the phylum Molluscs, Phallobranches, Mytilidae, Mytilidae, and the genus Mytilus. They are marine bivalve molluscs. The valleys are called Qingkou and Haihong. nutritional value. Edible mussels produced along the coast of China mainly include blue mussels, thick-shelled mussels and emerald mussels. Thick shelled mussels are one of the important economic shellfish in my country. Due to artificial overharvesting and poor breeding protection, the natural thick shelled mussels resources in sea areas are exhausted, and it is difficult to raise seedlings. Large-scale development of shellfish farming. In recent years, the annual price of adult shellfish has increased by 20%, and the economic value is high. The current p...

Problems solved by technology

[0003] The invention provides a kind of attachment and using method for improving the survival rate of thick-shelled mussel spat, which overcomes the conventional use of "transparent PP corrugated tile", "palm rope", "straw rope" and "polymer rope" in the process of artificial seedling cultivation. "Ethylene mesh" and other material attaching seedlings are screened and placed, and the attachment survival rate is only below 30%. Such a low attachment abnormality rate seriously restricts the development of thick-shelled mussel culture. Survival rate of shell mussel juveniles to increase larval metamorphosis rate, save the cost of thick shell mussel culture, and promote the development of thick shell mussel culture.
