What about darters, could or should they be moved to a pond?
I'm having a tough time really understanding what you are looking for here, I think. The fish in the creek survived on their own prior to you taking ownership of the land, so there is obviously no need to move the fish to your pond for any reason other than just wanting to do so. If you are cool with the idea that there's a chance they could carry parasites or other unwanted stuff into your pond and maybe impact your purchased fish, then go for it. If you aren't comfortable with that chance, then I say don't go for it. The reality is that if you want to add the fish just for fun, then you need to do it and watch how the experiment pans out for you. It might actually be a fun way to add to your pond's diversity and could lead to some fun time with your kids. If you are asking whether you should do so to ensure the fish survive the winter, my feeling is that it's an unequivocal no. Again, they survived just fine before you owned the place and will survive just fine if you never do anything to them.
The main question I had was about the fish making it through the winter or not.
I am sure most would make it but that does not mean they will not leave anyway when the water is up correct.
Nor does that mean new fish will not be trapped as well.
So I guess this just leaves me to decide if I want to fish and keep them then fine if not throw them back.
Now onto the thought of adding some fish from another pond, lake, creek, etc., what are some things to worry about?
I hear people say you can transfer parasites, disease, etc., but have yet to find examples.
Does anyone have, or is there a post on here with a list of items like parasites, diseases, plants, etc. that could be moved and why they are a problem.
I would just like to know some of these, I am aware of the grubs that snails host but have not heard of other issues.
Also is there really a River Bass?
I was always under the impression of the Northern and Florida strains and that was it.
