Embodiment Construction

[0008] The nursery of thick-shelled mussels includes steps such as intensive cultivation of broodstock, induction of spawning, hatching of eggs, larvae cultivation, and juvenile cultivation. Wherein in the larva cultivation step:

[0009] Cultivation conditions: water temperature 14~21℃, salinity 25~28, pH 8.0~8.2, dissolved oxygen above 5mg / L, ammonia nitrogen below 0.2mg / L, light 500~1000LX.

[0010] Change the water: Change the water once every morning with the siphon method or the bottom drainage method, and gradually increase the total water change from 30% to 50%.

[0011] Feed: golden algae, diatoms, chlorella and flat algae, feed twice a day, that is, feed once in the morning after changing the water, and feed once in the evening according to the density of algae in the cultivated water. Feed combination and feeding amount at each stage of larvae (expressed in the density reached by the algae in the cultivation water):

[0012] stage of larval development

Abstract

The invention provides a artificial breeding method for Mytilus coruscus, which comprises the step of larval breeding with the water temperature of 14-21 DEG C and the salinity of 25-28. Water is changed once through siphonage or a method of discharging water from the bottom of a pool in the morning every day, and the total water change volume is gradually increased from 30 percent to 50 percent; bait is taken as algae and fed twice every day, namely, being fed once after water change in the morning, and being fed once more in the evening according to the density of algae in the cultivating water body, so as to satisfy the requirement on algae density. The method provided by the invention has the advantages that as the prior art is further researched, the requirement on water temperature in the larval breeding step is decreased, and the breeding process is more reasonable by optimizing other parameters, therefore, compared with the prior art, the energy consumption is low, and the bred young Mytilus coruscus is strong.

Description

technical field [0001] The present invention relates to a method for artificial seedling cultivation of thick-shelled mussels, especially a method for cultivating larvae, which belongs to the technical field of raising fish in agriculture which is necessary for human life. 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, but also has good medicinal and therapeutic effects. Edible mussels produced along the coast of China mainly include blue mussels, thick-shelled mussels and emerald mussels. Among them, thick-shelled mussels are large in size, good in nutrition and high in value. There has been a history of collecting wild seedlings for many years for cultivation. For a long time, the seedlings of mussels have relied on wild collection and a small amount of natural attached seedlings. The number of...
