It seems likely that fish key on the size and silhouette of emerging pupae rather than color or motion. It also seems likely that fish key on the motion of streamers and the changing silhouette of streamers while they are in motion. Flash and color are not as likely to be keys as motion, but contrast may well be an important key.

Those fish found with jewelry and tin cans in their bellies probably did not swallow them as they sat motionless in the water column, nor did they graze them up off the bottom.
