Abstract

For incubation of eggs, prophylactic treatments are applied to minimize negative effects of microorganisms on eggs and larvae. The effects of treatments with formaldehyde, acriflavine and glutaraldehyde to spotted rose snapper Lutjanus guttatus eggs, were studied. Reduction of colony forming units (CFU), the percentages of hatching, live larvae, live normal larvae and larval size, were studied. Best treatment with significant reduction of CFU, but without observable effects on the eggs with controls was with acriflavine at 5 ppm.
