Mikrosal is used with forage mixtures. The forage mixture containing 2% of Mikrosal is singly applied without the preliminary hungry diet in the standard way of free-access feeding.

The forage mixture with Mikrosal is prepared directly in the fish farm. For this purpose 98 kg of forage mixture is loaded directly into the mixer of any type, 2 kg of  Mikrosal are added and carefully mixed, then  25% of warm water added and  again carefully mixed.

Before a mass dehelmintization, each series of Mikrosal is preliminary tested on fish from one pond, observing fishes within the next 3 days.

If there are no complications, the preparation can be used in all fish farming ponds.

The evaluation of the efficiency of treatment is carried out by helminthological dissection of 25 fishes from each pond before giving a medical forage and of 25 fishes on the fourth or fifth day of treatment. If necessary, Mikrosal is applied again 10-20 days after the first treatment.
