Not really sure how old they are. I know there are tons of variables to attain trophy bass and some of them like fertilizing and such I have never messed with. There is hardly any cover in this pond which I thought would be good as the forage has not many places to hide but I'm just guessing. Are the bass relying on the pellets and not putting a dent in the gill population? Should I try to put some shad in there? It's frustrating to fish a couple nearby ponds that arent managed and catch 3-5lb bass from them and they are only a couple acres. Will the pellets only get them so big? Sorry for all the questions.
