Don't be.

I went with a low density stocking strategy in order to keep trash fish out my pond. I will say don't buy a lot minnows as there is likely to be some undesirables mixed in with them. I made that mistake and probably have some bullheads now. You could stock a few dozen fathead minnows now just to keep the mosquito larvae down. This would give you the opportunity to make sure they are all indeed fatheads. They will reproduce like mad over the summer and by the time you are ready to stock some game fish there will be a forage base established for your fingelring fish.

What do you want to put into your pond?
