It was stocked in Feburary of this year. At the time the crappie and bg were about 2-3 inches the cc were about 4-5 inches. I recently caught a cc, it was 8-9 inches guesing. I did not measure it. I have no idea what the survival rate is. I can take out however many cc I need to now, but would prefer to wait until spring when I hope they will be big enough to eat.
