ZAROR, L et al. Saprolegnia parasitica in salmon and trout from southern Chile. Arch. med. vet. [online]. 2004, vol.36, n.1, pp.71-78. ISSN 0301-732X. http://dx.doi.org/10.4067/S0301-732X2004000100008.
Thirty five strains of Saprolegnia were isolated from salmon and trout, obtained from the IX, X and XII regions in southern Chile. The strains were obtained from eggs, gills and fins of alevins and smolt phase of different species of salmonids: Salmo salar (Atlantic salmon); Oncorhynchus kisutch (Coho salmon) and Oncorhynchus mykiss (rainbow trout). The strains were re-isolated and purified in Sabouraud agar, Lactrimel and MAO agar, supplemented with antibiotics. The strains were cultured in distilled water and hemp seeds, for the production of sexual structures, and for their morphological identification. All strains collected, were identified as Saprolegnia parasitica. This species was the only one isolated of its genus.
