The article analyzes an aquatic fishing control systems, using a selective electromagnetic emitter functioning in the optical band. Light sources have been created and are used in fishing for Caspian sprats, anchovies, Black Sea scads, sauries and calamari. But changes are taking place in the species composition due to the depleted state of commercial fishing stocks. Moreover, in the critique’s view, to avoid the accidental catching of turtles and frogs, the automated control systems for aquatic fishing need to be optimized and have their basic information quality elements refined. Objectively, optimization would limit optical information to the control system, which includes the ’signal-noise’ function. This document features analytical expressions for the specified function of the Caspian sprat fishery, formulae for describing the light source’s spectral emissivity, information on underwater light transmission, and data on the sensitivity of the eye fish (allowing the researcher to investigate the dependence of the function within the parameters of the selected fishing control system).
