After that, take out the fish from the cod net, then reverse the two reels to lower the cod net and net to a predetermined position on the deck, and then throw the sleeve net to be thrown ahead on the deck while rotating the reel. And put it in the casting net standby state, and reversely rotate the reel in the order of the sleeve net, the net, the cod net and the other sleeve net wound on the reel when the net is cast. It is characterized by letting it cast a net.

[0035]

According to the present invention as set forth in claims 1 and 2, it is possible to perform a net-pulling net using a net winch, and the net is first cast by rotating the reel of the net winch. Can be pulled out onto the deck, the other sleeve net can be left wound on the other reel, and the spinning net can be prepared for the next casting net. As a result, it is possible to swiftly and reliably cast the net with a small amount of manpower, and it is possible to improve work efficiency and fishing efficiency.
