  Extinguishing measures for large jellyfish (Echizen jellyfish) that have caused a large amount of damage to the fixed net fishery, such as damaging nets and fish gear or reducing catches, by visiting a lot in the coast of Tohoku and entering the fixed net There is nothing to see in the past.

  The large jellyfish that causes damage to the nets and fish gear by hanging on the stationary net, the large jellyfish that entered the stationary net together with the fish will be an obstacle to the work when lifting the stationary net and landing the fish, Although it is excluded outside the net, the exclusion work is to remove the large jellyfish as it is to the sea outside the net, so it will be applied to other stationary nets, so it must be cut into small pieces and excluded, Usually, it is done by cutting and removing jellyfish one by one using a hand tool, which is a time-consuming and time-consuming work, and the workability of fixed net fishery operations is significantly deteriorated. There is.

  The problem that arises in this manual jellyfish removal processing means can be solved by developing a discharge discharger with high discharge and processing capacity driven by power, and dealing with it, As pre-processing work for this landing, the jellyfish contained in the stationary net together with the fish are discharged and removed from the net, and only the jellyfish is selected not to damage the fish contained in the net. It must be discharged outside the net, and when discharging the jellyfish into the sea outside the net, it will affect other stationary nets. There is a restriction that the cutting process must be performed in advance, and that these processing operations must be performed quickly.

  The problem to be solved by the present invention is to pick out a large jellyfish that has entered a stationary net, without damaging the fish in the stationary net, and to discharge it outside the net as a state of being cut into small pieces. However, it is to obtain a power-driven large jellyfish discharger that can be efficiently operated.
