Abstract :This review examines the effectiveness and dosages of chemical and herbal disinfectants used against fungal infections encountered by trout (Oncorhynchus mykiss) eggs during incubation. Formalin, potassium permanganate and copper sulfate are prominent chemicals among disinfectants. Formalin provides effective antifungal treatment when used in concentrations of 1000-2000 ppm, but it can have toxic effects in excessive doses. Potassium permanganate can control fungal pathogens when applied at concentrations of 1-5 ppm, but it can have negative effects on fish at high doses. Copper sulfate helps prevent fungal infections when applied at a dosage of 0.5-1 ppm. Herbal disinfectants include tea tree oil, thyme oil and garlic extracts. It has been observed that tea tree oil and thyme oil can be effective against fungal infections when used at 0.5-1%. It has been determined that garlic extracts can reduce fungal infections when used at 1-2% on trout eggs. Plant-based disinfectants are compounds that generally have lower toxicity and may reduce adverse environmental impacts, but their effectiveness may be variable compared to chemical disinfectants. Future research should focus on evaluating the effectiveness of chemical alternatives and developing more sustainable methods.
