以上の事情を踏まえ、本発明は、ＴＢＴＯに代る安全か
つ有効な漁、ｉｐ＋防手段を提供するのを目的とす(Background) Fishing nets set up in the sea (fixed nets, aquarium AP4) are covered with flora and fauna such as snails, serpura, green lettuce, and sea lettuce, damaging the fishing nets and impairing the flow of water.
Damage such as weakening, killing, and sipping of the fish within 'fI occurs. Conventionally, to prevent these harms, cuprous oxide,
Antifouling agents such as tributyltin oxide (TBTO) have been used. (Problems with the Prior Art) However, cuprous oxide quickly turns into insoluble sulfide and loses its effectiveness in modern polluted ports due to hydrogen sulfide contained in seawater. In addition, organic heavy metal compounds such as TBTO,
It has become difficult to use because it is highly toxic to humans, accumulates in fish bodies, and causes environmental pollution. Even more recently,
At farms around the world that use antifouling agents in place of TBTO, damage from spider worms (Benedenia), a parasite of yellowtail, has frequently occurred at each farm. It has recently been discovered that this is due to its ability to exterminate spider mite eggs. For this reason, there is a strong desire among aquaculture farmers to develop a safe and effective antifouling agent for fishing nets. [Problem to be solved by the invention] Based on the above circumstances, the present invention aims to provide a safe and effective fishing and IP+ prevention means in place of TBTO.

０％、この内の酵素は２％以下が適当である。(Summary) In order to solve the above problems, the fishing net antifouling agent according to the present invention is characterized by containing a proteolytic enzyme and a binder. (Principle of the Invention) As a result of research, the present inventor has discovered that the reason why marine fouling organisms, especially the larvae of animals such as barnacles and the eggs of spider worms, adhere to fishing nets is due to the adhesive action of certain proteins secreted by these organisms. We have discovered that this is due to the adhesive protein, and that proteolytic enzymes are effective in eliminating the action of this adhesive protein. This is the principle of the invention. (Proteolytic enzyme @) As the protease used here, since the pH of seawater is around 8.2, alkaline protease is more effective than neutral protease. In addition, since the average temperature of seawater is 15 to 20°C, proteases that work at low temperatures are preferred. (Binder and treatment method) In order to attach water-soluble proteolytic enzymes to fishing nets, it is desirable to use a seawater-insoluble binder. Since enzymes are proteins, they are deactivated by heat, PI3 organic solvents, etc. Therefore, enzymes are mixed into a water-dispersible binder such as water-dispersible urethane or acrylic emulsion, and fishing nets are dipped in this and dried. However, it is preferable to use a photocurable resin in an organic solvent that does not deactivate the enzyme, add a photosensitizer, disperse the enzyme in an organic solvent that does not deactivate the enzyme, soak the fishing net, and dry it. There is also a method of attaching resin to fishing nets. The amount of adhesion to fishing nets is 5 to 2 in total, including enzymes.
0%, of which 2% or less of enzyme is suitable.

されることがない。When the present invention is applied to a fishing net, the action of the proteolytic enzyme contained in the net decomposes the sticky proteins secreted by the larvae of animals such as barnacles and the eggs of spider worms, resulting in these larvae and eggs losing their adhesive properties. Therefore, the net will not be contaminated for a long time.
