It's opening day of the bluefin tuna season; after a mediocre performance in the Outer Banks, Capt. Dave Marciano is ready for his first season aboard his new boat, the Falcon; Capt. Tyler McLaughlin copes with the unexpected loss of his mate.

It is the second week of the bluefin tuna season; a familiar boat enters the fleet, igniting old rivalries; Pinwheel's crew members continue to mourn for Nick; the Wicked Pissah crew struggles to maintain its lead.

A familiar face returns to GloucesterP to compete for the title of top bluefin fisherman

Bad luck strikes the fleet, and the captains struggle to turn their fortunes around.

Capts. Dave Marciano and TJ Ott struggle near the bottom of the leader board; Capt. Dave Marciano's nephew, Jay, brings a shot of energy to the Falcon; Capt. Tyler McLaughlin strives to pull ahead; all three captains turn to family members for help.

An unexpected crowd of boats challenges the captains to find new spots for bluefin.

It's almost the midpoint of bluefin fishing season, so the clock is ticking; new alliances are built and battles continue in the race for a payday.

Stormy weather hits, and one captain brings in a payday that shakes up the leader board.

As the season reaches a turning point, a change in the quota forces boats to push their limits, creating tension on the water.

It's a game changer going into week 10 of bluefin season when the quota drops from three fish to one fish per day, making the pressure mount; the quota also makes fishing far offshore a gamble because of the travel time and extra fuel costs.

Mechanical troubles plague the Falcon and a new boat of young fishermen joins the fleet.

The captain must decide whether to risk making their way further out to sea 170 miles away from Gloucester, Mass., where the fish promise to be big.

Capt. Dave Carraro commands the top-earning boat on the leader board, but nothing will stop the rest of the captains from pushing against all odds to take down the king.

With the untimely death of Pinwheel first mate Nicholas "Duffy" Fudge, defending champion Capt. Tyler McLaughlin questions whether he will be able to defend his title.

Pinwheel and Dot Com battle for the top prize but dark horse Hot Tuna upsets their equilibrium and turns this competition into a three-way contest.
