The objective of this study was to evaluate the economic effectiveness of various hormonal products for stimulating the reproduction of the cultured and wild forms of the common barbel Barbus barbus (L.). Three hormonal products were analyzed: Ovopel, Ovaprim (cultured and wild fish) and hCG (cultured fish). The economic effectiveness of hormonal stimulants was analyzed in view of ovulation rates, the price of hormonal products and spawner mortality rates. The cost of hormonal injection per 1000 eggs and 1000 hatchlings was adopted as an indicator of economic effectiveness. The best results were reported for hormonal stimulation using synthetic GnRH analogues during induced spawning of the barbel in a group of cultured fish. The above product’s effectiveness in the controlled spawning of cyprinids is demonstrated by high ovulation rates and high embryo survival rates.
