Hey D
Where I live I can fish off my dock and catch fresh and saltwater.
We have brackish water and both can live in it.
Just change baits to go from saltwater to freshwater and when they are hungry they don't care what kind of bait you have on.
Why sometime I throw a line in with no hook because they wont leave me alone long enough to catch a nap or drink a adult beverage while I'm out there on the pier.
