I have done it for sharks and things which makes the result increase alot but I just relized back when my pond wasn't filled with litter and actually just last summer we were fishing for bluegill and sunny, sunfish I call em Sunnies. Anyway I had a like 2 peices of bread left so I took peices of it for the fish and tossed it in I guess the action brought all the other fish like bass catfish pickerel ect..... Anyway I have done this a lot without relizing it and I was wondering does it really work or just coinsidence? Is it legal
