This video was made by Jonathan Jones AKA Redbeard, a New Zealand based fly fishing guide and videographer that in addition to trout fishing has a unique saltwater fishery. Seasonally, yellowtail kingfish come in to feed on the flats and can be sight fished for with a fly.  A tagging initiative is underway to help track and study them.  This effort was made possible in part by Smith Optics, Scientific Angler, Howler Brothers, Rising, Trippin on Trout and Tail Fly Fishing Magazine.
