Resumen:
Two fungal parasites isolated from the fish Odontesthes bonariensis in Argentina were
identified as Achlya racemosa and Saprolegnia ferax based on morphology and ITS rDNA sequence
comparison. Studies were conducted to determine the effect of culture temperature and culture medium
on growth rate and stimulation of sexual reproduction. Both isolates showed an increased rate of
vegetative growth with increasing temperature; the growth rate of Saprolegnia ferax was higher than
that of Achlya racemosa. Culture medium did not significantly affect growth rate of either species at the
same temperature. However, differences attributable to culture medium in the formation of sexual
structures were detected.
