Sounds like a cool place! How about some photos?
One thing to consider is that you could use the small "tanks" as species-specific, forage-only ponds. You could seine and dump the progeny into the big pond on a regular basis.
I have considered on a couple of the ponds. I especially like to do that with shad but I don't think they are deep enough for them to survive a winter. I have been trying to upload pictures but for whatever reason I can't. I can email them to somebody to upload.
