Just joined. Hope you might help me with your experience and knowledge.
Some very good fortune came the way of my fella, in the way of a small rural house. It has a small acreage now, and we expect to be able to add to it (connecting land) in the future. It needs a lot of work, but it's all good. He's native to the locale, so we're good with everything related to the area.
I haven't seen it yet, but he tells me there is a small area that will lend itself to being a full time pond, since it currently is a part time pond when irrigation ditches fill it. He feels it wouldn't be unreasonable to re-work it to make it a "real" pond.
The place is surrounded by farmland. A lot of it is rice - which leads to ... mosquitoes.
Near the house is a commercial chicken operation ... flies.
I've done loads of research on what it will take to contend with each of those pests. So far so good.
Then I came to the pond issue. There are already a lot of native dragonflies, likely due to the rice fields. They must be keeping the flies relatively manageable, because this place isn't nearly as bad as some places near commercial chicken houses. It's likely they may like our pond. I know the winged ones eat all the types of pests we'll have. Their nymphs love mosquito larva. Great.
However, could we supplement the pond with some native fish that could also help?
I read that pygmy sunfish are local to SE Missouri, but I don't know much about them.
I don't think regular mosquitofish might be a good idea - as they seem to not actually eat as many mosquitoes as their name might suggest (per some studies that call them invasive pests. I dunno if that's true.)
I thought maybe the Least Killifish would be good. (Heterandria formosa) - but then I see they probably wouldn't like winter in the pond.
I thought maybe regular bluegills would be fantastic - I mean - you could actually eat the extras - until I read that only the babies eat the mosquitoes and the adults might eat other mosquito eating critters.

What might you suggest for us? It's SE Missouri - near the corner - by Arkansas, Kentucky, and Tennessee.
PS: This is important - we are going to have various small farm animals - in limited number. Some will be muscovy ducks - which are mainly land-ducks, but they don't mind getting into a pond now and then. Will they decimate the fish if we let them in there? They're fantastic fly eating machines - the muscovies. I think it could be possible to keep them out of there and give them their own wading pool. (They're not as water oriented as other ducks.)
