Mastering techniques for conducting the controlled reproduction of a given fish species, the procedures for performing hormonal stimulation, and the choice of the appropriate hormonal preparation and dosage all have a significant impact on the effectiveness of spawning, and, in turn, on the quantity of stocking material produced. This paper presents reproduction techniques for pikeperch, one of the most economically valuable species of freshwater European fish. The methods discussed include cage spawning, the artificial reproduction of wild fish (obtained from the natural environment), and out-of-season spawning. The principles of stimulating spawning with either photothermal or hormonal methods are also described. It is demonstrated that using
