The pikeperch (Sander lucioperca, L.-1758) is a valuable fish species, with a high demand among human consumers, due to its superior nutritional and organoleptic characteristics such as: white flesh, soft texture, lack of intramuscular bones and pleasant taste. One of the main challenges of the pikeperch rearing technology is encountered during the first summer of the production cycle. The main desideratum during this period is to obtain large quantities of fingerlings per unit area, with the highest possible survival rate and low production costs, under the conditions specific to the rearing units. Therefore, the aim of the present study was to apply 2 different feeding regimes for the rearing of one summer old pikeperch in earthen ponds, as it follows: V1- with pelleted fish feed and V2- with live fish food. Thus, the experiments were performed at S.C.D.P. Nucet during three different rearing seasons (2018, 2019 and 2020), in triplicate. The best results were obtained in variant V2 (live food administration) and the followed indicators were survival rate, individual growth rate and production per unit area.
