In the fishing nets and fixed nets that have become popular in recent years, it is necessary to immerse the fishing nets in seawater for a long period of time. They adhere to the ropes and block the nets, resulting in insufficient seawater movement and damage to fish due to lack of oxygen, and in fixed nets, the net formation is poor due to increased resistance to ocean currents, and the weight increases during construction. This may cause difficulty in lifting.

The present inventors have developed a fishing net treatment agent that is effective in eliminating aquatic organisms, is harmless to fish, can stably maintain its effectiveness over a long period of time, and does not impair the flexibility of fishing nets. As a result of intensive research to develop this, it was discovered that these objectives could be achieved with a treatment agent containing zinc or manganese salt of ethylene bisdithiocarbamate as an active ingredient and cellulose acetate or cellulose nitrate as a binder ingredient. The present invention was made based on this knowledge.
