It is strictly prohibited to use fishery drugs with high toxicity, high residues, or triple toxicity (carcinogenic, teratogenic, mutagenic). It is strictly prohibited to use fishery drugs that cause severe and difficult-to-repair damage to the aquatic environment, it is strictly prohibited to directly splash antibiotics into aquaculture waters, and it is strictly prohibited to use newly developed human drugs as the main or secondary ingredients of fishery drugs.
Prohibited fishery drugs: phorate (Dafenglei), hexachlorocyclohexane, lindane (gamma-hexachlorocyclohexane), toxaphene (chlorinated camphene), DDT, calomel, mercurous nitrate, mercury acetate, carbofuran (Kebaiwei, Dafunong), chlordimeform (Kesiman), amitraz (dimethylaniline amidine), cyfluthrin (Baishujuzhi, Baishude), flucythrinate (Baohaojiangwu, flucythrinate), sodium pentachlorophenate, malachite green (basic green, basic block green, malachite green), tryparsamide, antimony potassium tartrate, sulfathiazole (Xiaozhilong), sulfaguanidine (sulfaguanidine), nitrofurazone (furanxin), furazolidone (liduoling), nifurpirinol (P-138), chloramphenicol (including its salts, esters, and preparations), bacitracin zinc (bacitracin), tylosin, avoparcin, olaquindox (olaquindox hydroxyethoxy), sudafat (fenbendazole aminomethyl methyl ester), diethylstilbestrol (diethylstilbestrol, artificial estrus hormone, including estradiol and other similar synthetic female hormones), methyltestosterone (methyltestosterone, methyltestosterone, including testosterone propionate, dehydrogenated methyltestosterone, and assimilated male hormones).
