Problems solved by technology

[0003] However, at present, the source of mysis is still mainly fishing, and less artificial cultivation is carried out. At the same time, the existing artificial cultivation methods still have a series of problems such as occupying a large area of ​​water body, high cost, and unclean bait. Therefore, the current scale There are some difficulties in cultivating

Embodiment 1

[0036] Such as figure 1 with figure 2 The mysis culture device shown in , wherein, 1 is a fish pond; 2 is a mysis cage; 3 is an aerator; 4 is a horizontal plane; wherein, the arrow represents the direction of water flow. The device is a cage structure, and the bottom area of ​​the cage is 30m 2 , the height is 1.5m, the mesh diameter is 0.28mm, and the upper surface of the cage is above the horizontal plane, and the vertical distance between the upper surface and the horizontal plane is 0.2m.

[0037] In spring or autumn, screen the complete and viable mysis and remove the harmful organisms; inoculate the screened mysis into the floating modular cage system placed in the grouper culture water, and the inoculation density is 300 / L; During the breeding process, the temperature of the breeding water is kept at 20°C, and the salinity of the breeding water is 30‰, and feeding and harvesting are carried out according to the growth of mysis. Two days after the inoculation, use a ...

Embodiment 2

[0044] Such as figure 1 with figure 2 The mysis culture device shown in , the device is a net cage structure, and the bottom area of ​​the net cage is 15m2, the height is 1m, the mesh diameter is 0.25mm, and the upper surface of the net cage is above the water level, the said net cage The vertical distance between the upper surface and the horizontal plane is 0.1m.

[0045] In spring or autumn, screen complete and viable mysis and remove harmful organisms; inoculate the screened mysis into the floating modular cage system placed in the seahorse culture water, and the inoculation density is 200 / L; During the breeding process, the temperature of the cultured water body is kept at 25°C, and the salinity of the cultured water body is 30‰, and feeding and harvesting are carried out according to the growth of mysis. Two days after the inoculation, use a flashlight to irradiate the mysis at night. If mysis swarms, it means that the inoculation is effective. Otherwise, it is neces...

Abstract

The invention belongs to the animal culture industry, and in particular relates to an artificial culture method and culture equipment of mysid. According to the artificial culture method of the mysid, the mysid is cultured in an aquatic economic animal culture pond and cultured in a floating modular net cage system placed in a culture water body; and the temperature in the culture process is below 30 DEG C, the salinity of the culture water body is 0 to 300 percent, and the inoculating density is over 100 pieces per liter. The modular net cage culture system is used in the culture method, the mysid is cultured in the aquatic economic animal culture pond, and the size of net cage modules is regulated according to the size of the pond, so that the space of the water body is fully utilized. Meanwhile, the modular net cage culture system prevents the mysid from taking water bottom detritus so as to ensure the cleanliness of the mysid serving as bait.

Description

technical field [0001] The invention belongs to the animal breeding industry, and in particular relates to an artificial breeding method and breeding equipment for mysis. Background technique [0002] Mysid shrimp belongs to Crustacea, Soft A subclass, and Mysidacea (Mysidacea). Mysis can adapt to a wide range of salinity and temperature, and is an omnivorous type. Due to the high nutritional value of mysis, the protein is close to 70% of the dry weight, and the fat is about 15%, and it has the characteristics of short life cycle, fast growth, easy cultivation, and sensitivity to poisons. Some countries use mysis to improve And strengthen the fish bait foundation, and thus improve the survival rate of seedlings, and achieved good results. [0003] However, at present, the source of mysis is still mainly fishing, and less artificial cultivation is carried out. At the same time, the existing artificial cultivation methods still have a series of problems such as occupying a l...
