ORGANISM-GROWING RESIN COMPOSITION, FISHERY MATERIAL, FISHERY MATERIAL FOR CULTURE, ARTIFICIAL ALGAE FIELD, ARTIFICIAL GATHERING-PLACE FOR FISH, AND PRODUCTION OF FISHERY MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an organism-growing resin compsn., a fishery material, a fishery material for culture, an artificial algae field, and an artificial gathering-place for fish, all exhibiting fiber characteristics well balanced with other fibers, a very low sweepback contact angle, excellent sticking of spores of algae, and excellent durability. SOLUTION: This organism-growing resin compsn. is a mixture of a synthetic resin and a compd. having at least three hydroxyl groups in the molecule (e.g. a pyrogallite compd.). The compsn. constitutes at least the surface of this fishery material; that is, the compsn. constitutes at least the surface of a fibrous structure selected from among ropes, nets, and knit fabrics. This artificial gathering- place for fish comprises members of which at least a part is coated with the compsn.
