Description	Pacu Piaractus mesopotamicus fed diets supplemented with three vitamins C and E levels (zero, 250, and 500mg vitamin/kg diet) were challenged with Aeromonas hydrophila under different temperatures. Fish were kept in 300L plastic tanks and fed during the first 60 days with diets without vitamins C and E, in an attempt to reduce vitamin sources. After this period, fish were maintained at an initial density of 14 fish/tank and test diets were offered during 60 days. At the end of the experiment, all fish were infected with 6×10(6)CFU of A. hydrophila/fish, intraperitoneally injected. No interaction of dietary levels of vitamin C vs. E on mortality was observed. Supplementation with vitamins C and E did not decrease the mortality rate of fish challenged with A. hydrophila. Regardless of vitamin supplementation, after challenge, smaller fish showed higher mortality than larger ones and the fish group maintained in an environment under higher temperatures showed higher mortality rate.
