- Abstract
Two saprolcgniaceous fungi, one recovered from Atlantic menhaden, Brevoortia tyrannus Latrobe, and the other from fresh water, were compared for their abilities to withstand salinity stress. Results of stress protein analyses indicated that vegetative mycelium of the isolate from menhaden was better adapted to mesohaline salinities than the freshwater isolate. Experiments testing the propagative ability of both fungi during salt exposure further suggested that the fungus recovered from menhaden was more salt tolerant and possibly survives in estuaries because of nutrients present in susceptible fish. Implications of the findings relative to the pathogenic potential of fish pathogenic saprolegniaceous fungi in estuarine water columns are discussed.
