I would suggest if that is the general plan then I would add the small BG/RES soon (by early summer). It is ok for FH and small BG to go in together. Small fish (yoy) morts go up if you stock small yoy LMB (2in) in fall to close to cold weather. The bigger and better conditioned the yoy are before cold temps the better the survival. If you are going to use larger yoy LMB (4-6 in in fall) then I would add the BG/RES now and also add about 20-25 adult BG (male and female) per acre early this summer. That way you know you will have reproducing BG next spring. As Theo notes it is a big puzzle depending on what you want and what fish you can get.
