Abstract | Ponds and small reservoirs are the main base of the fishing industry in Moldavia. However, the fish productivity of the ponds is still low. One of the causes of low fish productivity of the majority of ponds and small reservoirs is the high clogging of them with species of fish, which are hard to raise, mainly consumers of the same natural food on which valuable commercial fish (carp, bream, etc.) feed. Thus, for example, in the raceway of the Lazovsk Reservoir, trash fish (Leucaspius, gudgeon, bitterling, loach, small southern stickleback and bullheads) constituted 95.7% of the total in 1960. The report describes the methods used to limit reproduction of trash fish in all possible ways. |
