In the present study the infested fishes were exposed to 100 ppm & 200 ppm hydrogen peroxide 20% for thirty
minutes. The control infested fishes were examined and found to have a mean of 18 ±0.93 trophonts per gill
biopsy & 10 ±0.91 trophonts per skin smear. The fish that were to be treated with100ppm showed a mean of 10 ±
1.01 trophonts per gill biopsy in first week & 6 ±1.11 trophonts per skin smear. While in after six days, the count
was down to 5 ±0.93 trophonts per gill biopsy & 3 ±1.03 trophonts per skin smear .The fishes were retreated
with 200 ppm hydrogen peroxide for thirty minute for another 6days. The fish that were to be treated with100ppm
showed a mean of 10±0.93trophonts per gill biopsy in first week & 3 ±1.03 trophonts per skin smear. While in
after six days, the count was down to 4 ±0.93 trophonts per gill biopsy & 2 ±0.97 trophonts per skin smear.
Fishes that exposed to 100 ppm & 200 ppm of showed no mortalities recoreded.in the termination of experiment.
