In the method according to the invention live food organisms for aquaculture, such as rotifers and in particular Artemia, are treated with a bactericidal isothiazolin derivative to suppress bacterial contamination. The isothiazolin derivative is preferably a derivative of 4-isothiazolin-3-one, in particular 5-chloro-2-methyl-4-isothiazolin-3-one and/or 2-methyl-4-isothiazolin-3-one. It can be added as such to the growing media of the food organisms or be coated onto cysts of the organisms and/or included in an enrichment product for preparing an enrichment medium. The invention also relates to cysts of live food organisms coated with the bactericidal isothiazolin derivative and to enrichment products containing such derivative. |
