I agree add adult BG and RES. Also follow tried and true fisheries science advice from guys like Nate and forget any advice from Ken's. That stocking advice they provided is garbage. Think about this - A few FH (5 lbs per acre) and 5000 GG that don't produce hardly any offspring - and dye that suppresses plankton production - what were those 300 LMB going to eat - not much. With no structure or shallow water where were thee FH going to reproduce and live - not much.
Can you do a seine survey or make notes from observations looking for small fish , types and numbers. The more info the better.
