Recommended trout stockings average 300 per acre, with the usual variables at play (water depth, water quality, water temperature, available food sources, etc.).

I don't put trout in to fish for them or dine on them, although I certainly do enjoy eating trout. Mine are for my LMB to gorge on.

Here are some links with information on trout stocking:
