Giant Tuna Battle

Growing to over 1400 lbs, the blue fin tuna is a true titan prowling the oceans, and it's extremely powerful and fast. To help protect these endangered giants, Cyril is recruited by a team of biologists to travel up the East Coast of the USA and Canada, to catch and tag one. But that is easier said than done - with all the sharks stalking his boat, and the fact that tuna can break even the strongest equipment, Cyril really has his work cut out for him.
