Different fishes present in farms can be voracious predators of fingerlings to be stocked in the rearing. To eliminate these predators, calcium hypochlorite 65% (HC65%) and sodium dichloroisocyanurate 65% (DS65%) were evaluated in tilapia, yellow-tail characin and South America catfish juveniles. Initially, clear water assays were performed to determine the lethal concentration (LC) for these three fish species. Subsequently, tests were performed in a fish pond to observe the CL100. The CL100 at 8 hours in clear water was 4mg L-1 HC65% or 6mg L-1 DS65% for all three species. Already in ponds, containing 2.4% of organic matter in the soil, the CL100 was 30mg L-1, for both products. According to the result, it advises the concentration above 30mg of chlorine L-1 (3-6g m-2 DS65% or HC65% in ponds containing an average of 10 ~ 20cm water height).
