The prawn meat is delicious and has strong stress resistance, so that the prawn meat is suitable for long-distance dry dew transportation and is popular with prawn farmers and consumers. In 2018, the breeding yield of the marsupenaeus japonicus reaches 55,228 tons, and huge economic benefits are brought to coastal farmers. Because of the habit of killing each other and hiding sand, the marsupenaeus japonicus is mainly cultivated in a low-density mode of soil pond or mulching film sand laying at present, and the cultivation yield is limited. Therefore, the invention discloses a culture device and a culture method for improving the survival rate and the culture yield of the penaeus japonicus.
Sea grape (Caulerpa lentillifera) is a scientific name of Caulerpa lentillifera, is a 'rare marine large-scale green algae with rich nutrition, high economic value and ecological restoration type', and is called 'Changshengzhuan' and 'green caviar'. The sea grape is rich in minerals and vitamins, has high protein and low fat, and can supplement minerals and nutrients for human body. Compared with other algae, the EPA and DHA of the sea grape are higher, and the sea grape has the effects of purifying blood, resisting oxidation, cancer and tumor, and can also reduce blood cholesterol, thereby being an ideal health food. The sea grape artificial propagation originates from Japan, the breeding market prospect is very wide, but the sea grape has extremely high requirements on the growth environment and the water quality, and the artificial breeding difficulty is higher.

A method for culturing marsupenaeus japonicus and sea grapes in a mixed mode is characterized by comprising the following steps: the culture device for polyculture of marsupenaeus japonicus and vitis amurensis as claimed in any one of claims 2 to 7, comprising the following culture steps: (1) preparation of an aquaculture pond: fully disinfecting the culture pond, the curved surface sea grape culture device and the nanometer oxygenation device, and then injecting clean seawater with the depth of 1.2-1.5 m; (2) and (3) throwing the sea grapes: uniformly bundling the grapes in curved surface grape cultivation devices after removing attached miscellaneous algae, and bundling 8-15 plants in each device; (3) putting the marsupenaeus japonicus: selecting the penaeus japonicus seedlings which are detected not to carry pathogens, wherein the input amount of the penaeus japonicus seedlings is 80-100 tails/m2(ii) a (4) Daily management: feeding for 2 times every day, keeping the water temperature at 25-30 ℃, the salinity at 20-30 per mill, the pH at 7.8-8.5, the illumination intensity at 3000-5000 Lx, the dissolved oxygen concentration at 9-12 mg/L and the ammonia nitrogen concentration less than 0.2 mg/L; (5) disease control: cutting off the transmission path of water pathogens, fully aerating newly injected seawater after being disinfected by 15ppm bleaching powder, detecting that no residual chlorine exists, and manually cleaning once a day if the aquaculture water contains miscellaneous algae; (6) harvesting of sea grapes: when the growth of the sea grape reaches 0.5kg/m2The curved-surface sea grape cultivation device can be harvested, the curved-surface sea grape cultivation device is lifted by adjusting the floater to harvest, and proper seeds are reserved for primary harvesting; (7) capture of marsupenaeus japonicus: when the specification of the marsupenaeus japonicus reaches 10-50 g, the marsupenaeus japonicus can be captured, the water level is reduced to 10-15 cm, and the marsupenaeus japonicus is captured after all the grapes are harvested.
