Formalin treatments before eyeing and hand-picking of Arctic charr (Salvelinus alpinus) eggs – re-evaluating the timing of antifungal treatments ...
Arctic charr ( Salvelinus alpinus ) eggs in hatcheries are treated for fungal infections using formalin before, and hand-picking during the eyed stage. The relative effectiveness of the treatments was evaluated using a factorial design with the application of weekly hand-picking, and formalin treatm...
