GMRI scientist, Walt Golet, studies bluefin tuna. One of Walt’s research questions is how old are the bluefin tuna fishermen are catching?.  To figure this out Walt works with local fishermen. When fishermen catch a tuna they give Walt the head of the fish.  While the head is useless to the fishermen, it is very valuable to Walt. Inside the head is a tiny bone called an otolith.  The otolith holds the key to aging tuna, and answering Walt’s question. Check out his video to see how Walt answers his question.
