I keep notes of stocking rates when I come across them in writing. Here are a couple suggestions. The Michigan article is adamant about not mixing trout with other species, but that may be 1970's thinking.

For what it is worth: I just stocked my new 0.5+ acre pond today with 25 RBT from Imlay City. $5.00 each. Water temp is currently 64°F with diffused aeration. I plan on feeding. This is my first stocking, so we shall see.
