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.
