Welcome back Big Pond. Let's just crunch some numbers quickly(it's an engineering thang)
Let's say 500 fish survived. For them to each gain 1# just on feed at 2# in=1# out, you would have had to feed 20 50# bags of feed. For them to gain 5# each, 5000# of feed(4 to 5 times that much natural diet) How many bags per year have you gone thru? What is your forage base?
Blues, as you know, like mostly live forage, but will eat dead fish, ie, cut bait and feed. 1st thought is you need to have a variety of forage and that the size changes as the fish grow. I would start some large varieties of minnows behind a blocking net so they can get a jump on reproduction thru this summer. What other predators do you have and have you sampled them by angling? I know you like LARGE blues, so you need to whittle down the numbers. Just a WAG, you have a BIG POND?
