Harpoon Hunters

A group of four harpooners chase some of the highest-priced fish using only fast boats and aim; Niko must prove he can run a boat while Joe hunts to support his family as the fleet races to land the first bluefin worth thousands.

With the advantage of spotter planes, veteran Tyler and young gun Joe battle for the most monster bluefin until Joe helps strongman Niko get back into contention; when Niko's zapper fails, Tyler steps in to save the day.

As the bluefin fishery reaches its mid-season peak, three centuries-old fishing strategies compete for dominance.

As the fleet spots the first giants, Joe fights for his lead over Niko and Tyler; all bets are off as old-timer Bill joins the derby; Emmett struggles with the choice to fish without a plane; Dylan gets a $6,000 tuna.

Captain Joe Dion takes his sons to sea, landing two massive bluefin and witnessing a great white shark feeding on a humpback whale; Dylan's son Emmett earns his first harpoon attempt while Niko hunts the season's biggest bluefin thus far.

Captains Joe and Tyler hit bluefin gold as second-generation harpooner, Niko Chaprales, fails to land even one.
