FIELD: fishery, in particular, method which may be used in curative and prophylactic processing of hydrobionts. ^ SUBSTANCE: method involves feeding substance under control into aqueous medium until maximum allowable concentration at given exposure is reached; providing reduction of concentration of said substance in said medium; initially setting mass ratio of substance introduced into medium and mass accumulated in medium, with ratio being coordinated with exposure and water-exchange of medium; feeding substance under control at predetermined flow velocity directly into flow-through reservoir without cutting off water supplying process; determining substance concentration on the basis of dependence: F=Mo/Mtau x Q/V x tau, where F is dimensionless concentration criterion; Mo is mass of substance introduced into medium; Mtau is mass of substance accumulated in medium; Q is flow velocity of flow-through water in substance; V is volume of medium; tau is exposure, with Mo=gt, where g is flow velocity of substance per unit of time; Mtau=Wtau x V, where Wtau is maximal concentration of substance in medium at exposure tau. ^ EFFECT: useful utilization of fungicide and increased efficiency in treatment procedure. ^ 1 dwg, 1 ex |
