مجهول. Fungal infection on fish eggs leading to low hatching rate and production of larvae is a common problem encountered in fish hatcheries. Various disinfectants are applied on eggs for control of infection and improving larval survival of the aquacultured species. In this study, the doseresponse of methylene blue (MB) and hydrogen peroxide (HP) on the fungal infection and hatching success of eggs of Melon barb was studied. Fungal infection on eggs were observed during the incubation. Higher dosages of both MB and HP have resulted in significantly higher egg mortality and hatchling deformity (p<0.05). The MB dosage of 1.5 ppm has prevented the fungal growth on eggs along with improving the hatching rate and hatchling survival rate. HP dosage of 9.5 ppm has prevented fungal growth in the main study. Application of these disinfectants had increased 7-9% hatchling production than without using any disinfectant (control treatment).
