Deadliest Catch: Bloodline — Season 3

After a grueling Opilio season in Alaska, Captains Josh and Casey rejoin partner Jeff Silva only to discover unexpected competition at their lucrative fishing grounds in Hawaii. To succeed they'll need to follow another roadmap Phil Harris left behind.

Ever since Josh and Casey first arrived in Hawaii with Phil's fishing charts and dreams of an off season fishing business, Jeff Silva stepped up as the rock steady partner helping them find the fish. Now, Jeff faces a monumental change in his own future.

In the Season 3 premiere, Captain Josh Harris reunites with his estranged older brother Shane, opening a new door in his quest for their legendary father, Phil Harris' legacy and an unexpected new destination in his search of a warm water fishing empire.

In search of valuable Ahi tuna, Josh's crew ventures to the most treacherous fishing grounds in Hawaii -- the remote islands north of Kauai. But when their 36-foot greenstick snaps, they realize the fish aren't the ones biting off more than they can chew.

Facing two strikes with their Vegas buyers, Josh and Casey turn to Jeff for help from his secretive Hawaiian network. But when a short order leads to strike three, the guys get fired by their biggest client, leading Josh to leave Hawaii for new grounds.

Josh and Shane pick up a new trail left by their father that leads them to Wild Bill and an unexpected location in the Gulf of Mexico. In Hawaii, Casey and Jeff battle circling sharks to pull in large fish to help them rebuild a base of restaurant buyers.

With fresh clues from their father's past, Josh and his brother Shane head to Louisiana, where Wild Bill Wichrowski helps them follow a trail that leads to the man who built the Cornelia Marie and to rich new fishing grounds in the Gulf.

In the fishing hotspot of Venice in Louisiana, a buyer demands an unfamiliar freshwater species - and Josh and the team hook a prehistoric monster.

Josh and his brother Shane discover the most promising lead yet about what their father Phil was doing decades ago in the Gulf of Mexico. Casey and Jeff attempt to fill a challenging order by spearfishing in the murky water beneath the oil rigs.

Josh and Casey land a seafood order big enough to launch a second wing of their fishing business. But when Jeff gets an urgent call back to Hawaii, they must reach out for reinforcements gambling that Bering Sea veteran, Wild Bill, answers the call.

As Hurricane Ida slams the Gulf Coast, Josh, Casey and Shane are forced to abandon ship in a mass evacuation. With their fishing Mecca in ruins, they scramble to help survivors. Jeff closes a new deal in Kona and recruits fishing legend, John Hillstrand.

In the season 3 finale, after Hurricane Ida wrecks their Gulf Coast hotspot, Josh, Casey and Shane return to Hawaii where the dream began to complete their season. But even in paradise, mother nature has an even bigger disaster in store.
