An Aphanomyces sp recovered from and thought to be a pathogen of Atlantic menhaden was subjected to salinity stress to see if its behavior suggested that it was a salt-resistant isolate. Respiration during prolonged salinity exposure as well as hyphal morphology suggested a degree of salinity tolerance generally greater than previously reported for this or other saprolegniaceous fungi. Furthermore, zoospores were shown to germinate during salinity stress if exogenous nutrients are present.
