This is a short, but very cool video. The video gives a good example of how a bonefish searches for food using his highly refined senses. The video also show how bonefish align themselves to feed into the tidal flow. Near the end of the video (approx. 2:08), watch as the bonefish literally finds pay dirt. The fish tips down and digs in the marl with his mouth. You can see how bonefish puffs are formed. If you watch closely, you an see the excavated mud flow out through his gills.
A few things struck me with this video:
#1. How important it is to have a fly heavy enough to both get down quickly AND overcome the tidal flow.
#2. How it's always much further than you think. By that I mean you must deliver your fly (depending on its weight) well ahead of the tail, when a bonefish is tipped down busy excavating a morsel. Hitting this fish on the head would not work. He would never see the fly or he would feel the line as the tide carried the fly over his head and blow up.
#3. How unimportant it is to move the fly with what has become the conventional strip (see this). Obviously, the fish in this video sees no motion. When a bonefish is feeding, all he needs is to spot your fly. Constant repetitive stripping is often both unnecessary AND unnatural. Most prey species don't move very much… they try to hide on the bottom and usually do not flee. Prey species very rarely "get away". Their best chance is to hide! Bonefish are too "fleet of fin" to run from.
