If using advanced fingerling LMB (6-8in)in a pond with no adult large predators (LMB , NP , cats etc) then use fewer per acre than with 2in stockers. I will be using similar LMB this fall in a 12 acre lake and am only using 400. 30 per acre is enough.

The GSF will be ok. They will eat some FH and GShiner fry. What is your BG status? That is where you may need to focus.
