要となっている。2. Description of the Related Art When a fibrous structure such as a rope or a net is used in water, various aquatic organisms adhere to the surface thereof.
For example, in an anti-pollution sheet used to protect the surrounding sea area from pollution when performing civil engineering work underwater, such as construction of airports and bridges, algae adhered to the entire surface of the sheet in a few weeks and adhered Cleaning is required once every few months to remove the algae.

いる。[0003] In recent years, in addition to conventional marine aquaculture, aquaculture in pools installed on land, called onshore aquaculture, has been actively performed. In addition, since barnacles adhere in large quantities, there is a problem that the flow of water in the culture net is hindered, and the water quality in the culture net deteriorates rapidly. Some parasites of farmed fish breed by laying eggs on the net.

により環境が汚染されるという問題があった。[0005] In order to prevent these aquatic organisms from adhering, a method of attaching a toxic substance to a fiber structure has conventionally been adopted. However, since the fiber structure is used in water, the toxic substance is removed from the fiber structure. There has been a problem that the toxic substances that have flowed out more easily and have been washed away pollute the environment.

とが必要だからである。Means for Solving the Problems In order to solve the above problems, the present inventors first paid attention to the behavior of aquatic organisms attached to a fibrous structure. In other words, algae and barnacles, which are representative of organisms attached to fiber structures used in water, float in the sea as fine organisms, then attach to the fiber structures, and grow on the fiber structures. . For example, algae adhere to the fiber structure in a spore state, and then germinate and grow there.
On the other hand, barnacles, which are crustaceans, attach to the fibrous structure as plankton and then transform, after which they end their lives with being attached to the structure. Algae and barnacles do not grow unless there is sufficient light. The reason is that the growth of algae requires light for photosynthesis, and the growth of barnacles requires the barnacles to be exposed on the sea surface.

する負荷が格段に小さい。In the above-described sterilization mechanism using a photocatalyst, water adhering to the surface of the photocatalyst is radicalized by light, and this radical kills nearby organisms. Thus, in photocatalytic disinfection, light is the energy source for disinfection and, in theory, the effect lasts forever. In addition, the generated radical immediately reacts with a nearby substance and returns to a harmless substance. Therefore, unlike a general toxic substance, the load on the environment is extremely small.
