river rat welcome to the PB Forum, normally I wouldn't recommend putting wild fish in your pond due to possible disease or not being able to identify the species, but you have to decide that.
I get trout from a stream on my property but my pond is also supplied water from the same stream and I haven't had any problems, also I get some fish from a Mt. lake nearby but there are no problems with this remote lake.
If you can get your fatheads or golden shiners from a supplier it's probably a safer way to start your fish forage base.
