Recently, Liu Changlin, Yellow Sea Fisheries Research Institute, Chinese Academy of Fishery Sciences, and other research and invention of "a method for the conversion of chilled bait and live bait feeding of Lai's quasi-squid" was authorized by the national invention patent, patent number: ZL 202010582816.

The present invention discloses a method for transforming and feeding fresh bait of Ry's quasi-squid, which belongs to the field of
aquaculture technology.
The Lai's quasi-squid lives in the middle and upper layers of water, almost not active in the lower layer of water, does not feed on dead bait, does not prey on live bait living underwater, and it is difficult to domesticate and feed factory breeding bait

aquaculture technology.
The Lai's quasi-squid lives in the middle and upper layers of water, almost not active in the lower layer of water, does not feed on dead bait, does not prey on live bait living underwater, and it is difficult to domesticate and feed factory breeding bait
.
The present invention aims at the characteristics of Lyce's squid not feeding on bottom bait, and successfully domesticates the squid feeding on the bottom live bait by lowering the water level, reducing the distance between the squid and the bottom of the pond in the early stage of seed cultivation, and feeding compound feed to increase the activity frequency of mysis shrimp and fry feeding on bait; In view of the characteristics of Lay's quasi-squid immediately spit out after ingesting chilled bait, the present invention uses the method of cold anesthesia to anesthetize the live bait, after the squid feeds, the bait struggles in the mouth, so that the squid feels that it is feeding on the live bait without spitting out, and at the same time, the live bait after anesthesia recovery can survive at the bottom of the pool, and then be fed by the squid, and then domesticated to solve the problem that the squid does not eat the chilled bait; At the same time, when feeding the bait, Lay's quasi-squid actively competes for the bait in the sinking stage, in view of this feature, the present invention increases the sinking distance of the bait by raising the water level, prolongs the sinking time of the bait, and significantly increases the feeding frequency of the squid, thereby solving the problem
of domestication feeding of the Lay's quasi-squid bait.
of domestication feeding of the Lay's quasi-squid bait.
