As a kid we took a couple of cheap cans of fish-flavored catfood and pitched them out after we poked them full of holes with a "church-key" type can opener but I'm not sure that it helped all that much in a small lake wihout a current.
Reminds me of a time when I was feeding some white bread to the bluegills in the deeper end of a small farm pond... After about 5 minutes I see the big grey head and wide mouth of an 8 pound white cat appear from below trying to suck up the crumbs and smaller pieces that were slowly sinking to the bottom...

Needless to say, The blue gills "took a break" and let him have his fill.

I would of expected a carp but not a cat... Kind of funny the type of things that a guy can learn "by accident" just by spending time on the water...
