My friend has a pond which he will be using for trout, smallmouth and walleye. He wants to start a forage base. His water never gets over 59 degrees. What type of minnow would spawn in such a pond and make good forage for these types of fish.
Smelt!
Not technically a minnow of course.
Doubt you'd get a viable population in the pond anyway.
Why not stock with trout and feed pellets?
