It depends on how fast the YOY grow, and how large the trout are. Don't forget, you can be the predator too, by harvesting "X" amount of fish for the table every year.

It'll probably all depend on how many RBT you stock, what size they are, and what size the YOY fish are. Plus RBT aren't as piscivorous as Browns.

SMB wouldnt' be a bad idea. You could still stock RBT seasonally.
