These hard charging little tuna, also known as little tunny, are pound for pound one of the toughest fighters around. Occasionally  mixed in with schools of mackerel, this is one fish that is quite capable of spooling a light reel. Each on the fish pictured here, while seemingly innocuous, delivered a heart thumping battle for the angler. They have absolutely no food value whatsoever, unless you are adrift on a raft at sea for weeks.
