In industrial aquaculture, spawning of t*he Clarias catfish (lat. Clarias gariepinus) is complicated by the fact that it is impossible to obtain sperm due to the physiology of the fish. Fish farmers deal with the problem in different ways. They have to expect natural spawning, do a resection of the gonads or kill and dissect the fish (slaughter). We would like to propose a method for collecting sperm through the puncture of the gonads of the fish. The method is intended to save male broodstock. If the weight of the fish does not exceed 2 kg, the procedure can be performed any anesthesia. There is no need for the fish to be separated from the rest of the broodstock after the surgery. 43 of the 65 stimulated one-year-old males with an average weight of 1250 g have given motile sperm with a volume of 1.5 ± 0.1 ml.
