Good afternoon,

I just found this site today and it is awesome! More info than I can wrap my head around.

I have a one acre and quite deep (23ft in some spots) pond that I have been working on to fix a bass overpopulation problem for the last 5 years. Two years ago (2017) I decided to add 100 6-8" catfish to the pond for fishing pleasure. In 2018 I caught one catfish about 14", but since then I have not as much as had a bite from a catfish. I'm starting to wonder what happened to them all. The bass are coming along nicely but I am worried about my catfish investment. Should I start feeding a floating fish food to confirm their existence, or could that cause problems? Anybody have some other suggestions for confirming my whiskered friends are in there still? Thanks in advance from the newbie.
