hi cw, here's my humble opinion.
if you didnt see it on one of my other posts, i'll repeat it (told to me by a veteran fish farmer) "putting a few hundred fish in a 1 acre pond and throwing out some food for them is like putting a flake of hay on a thousand acres with only one steer walking around"
IOW, try feeding by hand first, in the same place, at the same time of day until the fish figure out its food this strange two legged creature is giving them. probably would help to make a loud repetitous sound like hitting a metal stake in the ground a few times every time before trying to feed. once you get a few, the rest will learn quickly, then turn yer feeder back on.
good luck
