What I would like to do is add a panfish that does not reproduce or only reproduces enough to keep the pond at a more or less even population. That includes adding or removing enough panfish annually to accomplish that.
If I find out that some trout have survived this summer, then would also like to add 50 to 100 trout each fall. One thing that I like about trout is that you have the ability to control population. Although it has become frustrating as I am only harvesting about 10% of the trout that I stock, the rest just seem to disappear.
