I have an idea on how to control the feeding of a dough type food. Take a 10' piece of 1" conduit with a bend or fitting on one end. Get a piece of rope, a used mesh potato bag and a concrete block. Put the dough in the mesh bag and close it. Cut a length of rope to suspend the bag from the end of the conduit so the dough is just under the surface. Put a concrete block on the end of the conduit on your dock to hold it in place.

You get to see the fish feed, control how long they feed and put any uneaten dough in a plastic bag for your next feeding. How about that!!
