A Comparative Study of the Effect of Hydrogen Peroxide as against Mallachite Green Used for Prevention and Control of Fungal Infection During Hatching Peroid in Rainbow Trout (Oncorhynchus mykiss) Eggs

Abstract

An experiment was conducted to investigate the effects of different doses of hydrogen peroxide on
fertilized eggs of rainbow trout as compared to 'use of mallachite green, which is commonly used in
hatcheries. For In vitro tests, treatment with 250, 500 or 1000 mg/1 ofH202 for either 15 or 30 min was
shown to be effective in control of fungi (controlled fungi in petridish) , and for In vivo test, treatment
with 250 mg/l of H202 for 30 min at 7°C was adequate for complete fungal control. There were no
significant differences doserved with 2 mg/l malachite green in terms of either percentage of eggs
infected or mortality until eyed egg stage . The results indicate that H202is not only not dengerous for
hygienic and environemental conditions but prolitable and suitable due to oxygen release and
improvement of water quality
