The objective of this study was to evaluate the technical viability of the ooplankton enriched used in the feeding of pacu (Piaractus mesopotamicus) pos-larvaes. In the Environmental Station of Itutinga of the Energy Company of Minas Gerais (CEMIG) this experiment was developmented, for 5 days last , the pacu larvicultura, by using 30 plastic boxes with capacity of 30 liters of water and continuous renewal, in a density of 10 powder-larvas per liter; they were appraised 6 feeding treatments: ooplankton without enrichment, ooplankton with 4 different enrichment levels (0,1; 0,5; 1,0; 1,5 g of fish oil) and artêmia náuplios, in a randomly blocks design with 6 treatments and 5 repetitions. The performance of larvaes as well as length, weight, survival and resistance to the stress were evaluated. The results shown that the ooplankton enriched is viable in the pacu (Piaractus mesopotamicus) pos-larvaes performance in terms of length , survival and the resistance to the stress
