Even in freshwater we have things like whirling disease caused by a parasite that seriously impacts trout populations and is very communicable to other fish, some species (rainbow and cutthroat) are dramatically impacted while others are somehow resistant (browns and bulls). It’s actually a pretty big issue out west for trout fisheries after it made it’s way from Europe in the 50’s
