Abstract

The invention discloses a cultivation technology for planktonic larvae of mytilus coruscus, and relates to artificial shellfish cultivation. The cultivation technology for the planktonic larvae of the mytilus coruscus comprises the following steps: selecting a cultivation time, selecting a cultivation sea area, building an outdoor cultivation pond, cultivating the planktonic larvae, performing cultivation condition management, and performing feeding management. According to the cultivation technology, the survival rate of the planktonic larvae is increased, spat bodies are enlarged, a problem of two 'dangerous periods of spat sinking' ubiquitous in artificial cultivation is solved through a research, a technical problem is solved, and the cultivation risk is lowered.

Description

technical field [0001] The invention relates to the artificial culture of shellfish in the field of aquaculture, in particular to a technique for cultivating planktonic larvae of thick-shelled 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-shell mussel is one of the important economic shellfish in my country. Due to overharvesting and poor breeding protection, the natural thick-shell mussel resources in sea areas are exhausted, and it is difficult to raise seedlings. The large-scale development of farming. In recent years, the annual price of adult shellfish has increased by 20%, and the economic value is high. The current price is about 8 yuan per catty. Thick-...
