We did put sturgeon in the pond - but if they (us) said it was to control sunfish that is a pretty lame reason because they aren't going to do that.
There is a misconception that sturgeon are used to clean ponds and hatchery raceways and control small fish species and that's just not reality.
The fact is more likely that the person who put them in there wanted to see how they would do in the pond as a way to create a new type of fishery.
The water quality in this lake is horrible and I know that there are groups looking at ways to control the problem. If I had to make a suggestion it would be to use Endothall. This is what we used in Kress Lake. It targets only milfoil, does not harm fish or wildlife or people (although there is a mandatory water closure for a few days) and is VERY effective. Another alternative is grass carp.
The alternative that I have heard mentioned, that I do not like at all, is to drain the pond. That puts the warmwater fish, stunted or not, at too much of a risk for loss - although I would go in and remove as many as possible - this lake is a good water for our channel cats.
I will be sampling this water in May to see what is going on with the sunfish/catfish and figure out what we can do to get the warmwater fish back on the right track.
