Embodiment 1

[0026] Select thick-shelled mussels with large individual, fresh shell surface, complete gills, full gonads, orange-red ovaries, and milky white testes as parents, clean up the silk and body surface attachments of the thick-shelled mussel parents, and then use seawater to clean them. After rinsing, put it in a potassium permanganate solution with a concentration of 10mg / L for disinfection for 10 minutes, and then put it into a culture pool for intensive cultivation.

[0027] Thick-shelled mussels were placed in a culture tank with a water temperature of 15°C, and then the temperature was raised to 21°C at a rate of 0.5°C per day. During this period, all seawater was replaced once a day, and the bait golden algae was fed twice a day. The feeding density was 2,000,000 cells / ml until the gonads are mature and the temperature is constant for delivery.

[0028] Cover the thick-shelled mussels with artificially ripened gonads with gauze, firstly dry them in the shade for 4 hours, an...

Embodiment 2

[0034] Select thick-shelled mussels with large individual, fresh shell surface, complete gills, full gonads, orange-red ovaries, and milky white testes as parents, clean up the silk and body surface attachments of the thick-shelled mussel parents, and then use seawater to clean them. After rinsing, put it in a potassium permanganate solution with a concentration of 15mg / L for disinfection for 10 minutes, and then put it into a culture pool for intensive cultivation.

[0035] Thick-shelled mussels were placed in a culture pond with a water temperature of 15°C, and then the temperature was raised to 22°C at a rate of 0.5°C per day, during which all seawater was replaced once a day, and golden algae were fed 3 times a day, and the feeding density was 2,000,000 cells / ml until the gonads are mature and the temperature is constant for delivery.

[0036] Cover the thick-shelled mussels with artificially ripened gonads with gauze, firstly dry them in the shade for 5 hours, and then st...

Embodiment 3

[0042] Select thick-shelled mussels with large individual, fresh shell surface, complete gills, full gonads, orange-red ovaries, and milky white testes as parents, clean up the silk and body surface attachments of the thick-shelled mussel parents, and then use seawater to clean them. After rinsing, put it in a potassium permanganate solution with a concentration of 20mg / L for disinfection for 5 minutes, and then put it into a culture pool for intensive cultivation.

[0043] Thick-shelled mussels were placed in a culture tank with a water temperature of 15°C, and then the temperature was raised to 24°C at a rate of 1°C per day. During this period, all seawater was replaced once a day, and the bait golden algae was fed 3 times a day. The feeding density was 3,000,000 cells / ml until the gonads are mature and the temperature is constant for delivery.

[0044] Cover the thick-shelled mussels with artificially ripened gonads with gauze, firstly dry them in the shade for 6 hours, and...

Abstract

The invention relates to an artificial spawning and cultivation method for mytilus coruscus. The method comprises the following steps of parent selection, intensified parent cultivation, artificial acceleration of maturation, artificial spawning, larvae rearing, larva cultivation and juvenile mytilus coruscus cultivation. The artificial spawning and cultivation method has the advantages that the season limit on mytilus coruscus reproduction is broken through, the time limit on mytilus coruscus reproduction is avoided, and the artificial spawning and cultivation method is of great significance in developing juvenile mollusk production and sustainable cultivation of economic mussels such as mytilus coruscus. On the basis of existing artificial cultivation technology for mytilus coruscus, through further study, experiment parameters are optimized for control over artificial spawning and larvae hatching conditions in the experiment process, the cultivation technology is more precise, and the cultivation hatchability and young mytilus coruscus survival rate are improved.

Description

technical field [0001] The invention relates to the artificial breeding of shellfish in the field of aquaculture, in particular to a method for artificially inducing spawning and cultivating of thick-shelled mussels. Background technique [0002] Mussels belong to the phylum Molluscs, Phallobranches, Mytilidae, Mytilaceae, and the genus Mytilus. They are marine bivalve molluscs, commonly known as mussels and sea reds. Their dried products are called mussels, which are highly nutritious. It also has good medicinal and therapeutic effects. The cultured mussels in my country mainly include blue mussels, thick-shelled mussels and emerald mussels. [0003] Thick-shelled mussels are seawater economic shellfish with high nutritional value. They have high edible value, broad breeding prospects and market development potential. They are distributed along the coasts of the Yellow Sea, the Bohai Sea and the East China Sea. There are many natural resources in the eastern sea area such...
