Process for the protection of fish and invertebrates and all their stages of development against or for the treatment of mycoses caused by fungi of the genera Saprolegnia, Aphanomyces, Achlyaflagellata and other species important in aquacultures by use of 2-[[[[1-[3-(1-fluoro-2-phenylethyl)oxy]phenyl]ethylidene]a mino]oxy]methyl]alpha-(methoxyimino)-N-methyl-alphaE-b enzeneacetamide, amisulbrom, cyazofamid, enestrobin, famoxadone, fenamidone, fluoxastrobin, orysastrobin, picoxystrobin and pyribencarb. This use leads to an inhibition or destruction of pathogenic fungi.The composition, comprising at least one fungicide selected from the abovementioned group for use in fish farming and keeping is suitable for the prophylaxis and therapy of diseases of fish in aquaculture, in breeding ponds, breeding tanks, aquariums, natural stretches of game fish waters, ponds, and marine fish farms. Addition to the water and feed and direct application are the associated use forms. The addition of the composition according to the invention to the water decreases fungal infections of spawn and fish.一種用於保護魚類及無脊椎動物及其全部的發育階段以對抗或治療由水黴屬(Saprolegnia)、絲囊黴屬(Aphanomyces)、鞭綿黴(Achlyaflagellata)真菌及水產養殖重要的其他種真菌造成之真菌病的方法，其藉由使用下述之化合物：2-[[[[1-[3-(1-氟-2-苯基乙基)氧]苯基]亞乙基]胺基]氧]甲基]alpha-(甲氧基亞胺基)-N-甲基-alphaE-苯乙醯胺、吲唑磺菌胺(amisulbrom)、賽座滅(cyazofamid)、因司唑賓(enestrobin)、凡殺同(famoxadone)、咪唑菌酮(fenamidone)、氟嘧菌酯(fluoxastrobin)、肟醚菌胺(orysastrobin)、啶氧菌酯(picoxystrobin)及吡本卡布(pyribencarb)，此種用途造成一種病原性真菌(pathogenic fungi)之抑制或摧毀。包含至少一種用於魚的養殖及管理之挑選自上述類型之殺真菌劑之組成物係適於用預防及治療在繁殖的池塘、繁殖的貯水槽、水族箱、天然獵魚場之延伸處、水塘、及海魚農場，供水產養殖中的魚之疾病，相關的使用型式可為加至水及飼料中及直接的施用，添加根據本發明的組成物至水中係減少魚苗及魚的真菌感染。
