Abstract

A method for controlling fish parasites by administering to fish having such parasites or to a habitat of fish having such parasites an effective amount of at least one substituted 1,2,4-triazinedione of the formula ##STR1## in which R.sup.1 represents optionally substituted aromatic radicals or represents optionally substituted heteroaromatic radicals linked via carbon; X represents O, S, SO, SO.sub.2 or -CH(CN)-; R.sup.2 represents one or more identical or different hydrogen, halogen, nitro, alkyl, alkoxy, halogenoalkyl, or halogenoalkoxy radicals; and R.sup.3 represents hydrogen, optionally substituted alkyl, alkenyl, alkinyl, or aralkyl; or a salt thereof with a base.
