FIELD: fish farming.
SUBSTANCE: electro-optical transducer for fish feeding has post, supply unit, photorelay and case inside which there is attracting radiation source is located. Radiation source has one red (λ=624 nm), two green (λ=522 nm), two blue (λ=469 nm0 and one ultraviolet light-emitting diodes. Attracting radiation source is switched on by means of photorelay. Coordinates of chromaticity of radiations mixture are equal to x=0,22943 and y=0,23662 according to chromaticity diagram.
EFFECT: improved efficiency.
