Hello guys , new to the forum but been reading alot of stuff on here past couple weeks. After all my reading i have come to the conclusion i have messed up in everyway possible. I redug my pond in 2009 and stocked it with 250 blugill and 250 redear and 75 catfish. Also fathead minnows. At the time i wanted mainly a catfish pond. Well 2 years later i think i started adding bass, 4 or so 12 inchers. Then i threw in some whoppers, 2 five pounders and few in the 3 two 4 pound range. Then i added some crappie. It gets even better tho. I then threw in 3 flatheads. Two were 12 inchers and one was 4 lbs. pond is 1/3 of an acre. So problem is i am trying to grow big bg and not having much luck. I have recently caught out both of the smaller flatheads but cant get the bigger one. I feel there isnt many crappie left in there as i have been taking them out and rarely catch one anymore. I put in hybrid blugill past two springs and they seem to be disapearing also. I added some big male bg couple weeks ago to help my other bg not reach maturity to early. Sorry for long post here but whats everybody think. I called a biologist today about killing everything out and starting over. Also have removed many of the catfish guessing maybe 20 left. I feed my fish too started aq500 this year but fish get fewer and fewer eating.
