Blueys have become as popular if not more so than mackerel over the last few years. The name bluey was developed for the fishing bait market, for the asian food market they are saury or pacific saury to be exact. At first people thought it was just a gimic but their potential as a bait soon became apparent when anglers started to use them and gained trust in their ability to catch fish whether it was a pike or a bass or ray. Saury are very high in oil and have a destinctive scent of their own so well worth a try.
