Welcome to the forum Yurdon, sounds like your planning a real zoo of a pond. I agree with JHAP, watch the total poundage of fish so your pond can handle the diversity.
You didn't mention if you had aeration, which would be a good addition especially with Trout.
The main thing now is sample the pond in the spring to see if you had winterkill of any species.
Good luck, and Trout Rule!!
