Abstract

PURPOSE:To obtain a red tide controlling agent, consisting of a specific polyunsaturated fatty acid ester, capable of exhibiting excellent red tide controlling effects by addition of a small amount thereof and having improved dispersibility and solubility without clouding even in dissolving in seawater. CONSTITUTION:A red tide controlling agent consisting of polyethylene glycol ester of an 18-22C polyunsaturated fatty acid, preferably a mixture of 30-90% monoester with 10-70% diester. Eicosapentaenoic acid, docosapentaenoic acid, arachidonic acid, linolenic acid, etc., are cited as the 18-22C polyunsaturated fatty acid which is a constituent component of the above-mentioned ester. Polyethylene glycol having 40-2,000mol.wt. is preferred as the polyethylene glycol which is the constituent component. The afore-mentioned controlling agent in a small amount (about 10ppm) may be added to seawater may be added and can be used by scattering and dissolving in seawater and further coating fishing nets or blending with coatings for fishing boats. Red tide controlling effects can be expected for a long period.
