The paper includes the results of experiments on the combat of philopod crustacean (Cyzicus sp.) which cause significant economic losses to the post-embryonic development of common carp and Asian cyprinids (silver carp, bighead carp and grass carp). To combat them, the effectiveness of the insecticide Proteus-OD 110 was tested, correlated with the application of technological procedures for the preparation of the ponds adapted for the growth of fish larvae. The experiments were conducted at S.C.D.P. Nucet, within the Mircea-Vodă experimental base. In order to ensure a profitable harvest, before the stocking of 3-5 days old fish larvae, the ponds were prepared according to the technological procedures. Disinfection and loosening of the bottom of the ponds was achieved by administering quicklime (CaO) in the amount of 200-1000 kg/ha and to increase the productivity of the ponds, manure (5000-10000 kg/ha) and rice bran were administered. In conclusion, in order to obtain optimal results in the period of post-embryonic development and growth in first year of cyprinids, we recommend that the technological instructions be adapted to each type of technology.
