Deadliest Catch: Bloodline

Deadliest Catch: Bloodline (sometimes shortened to Bloodline) is an American documentary and reality television series that premiered on April 14, 2020, on the Discovery Channel. Bloodline is a spin-off of Discovery Channel's Deadliest Catch. In contrast to the program's usual setting in the Bering Sea during crab fishing season, Bloodline is set in Hawaii. The show's three-seasons follow fishermen Josh Harris, his business partner Casey McManus (both captains of the Cornelia Marie on the Deadliest Catch series), and Jeff Silva as they investigate scribbles and notes found on Hawaiian fishing charts left by Josh's late father, Phil Harris. Bloodline was launched the same day as the season 16 premiere episode of Deadliest Catch. Discovery cancelled the series and removed all episodes from its Discovery+ streaming service in September 2022 after renewed attention was brought to a 1999 sexual assault case involving Harris.

Premise
As the boat Cornelia Marie was being remodeled, Josh Harris found Hawaiian fishing charts that his late father, Capt. Phil Harris, left behind. Josh and his business partner, Casey McManus, venture to the Hawaiian Kona Coast in search of ahi tuna and to learn about Phil's time spent there in the 1980s. While in Hawaii, Josh and Casey team up with a local commercial fisherman Jeff Silva for help in better understanding the coastal fishery, translating Phil's charts and notes, and guiding them on their new endeavor—catching tuna, each worth about $2,000. The hunt will also include barracuda, swordfish, and other underwater species. Johnathan Hillstrand, former co-captain of Deadliest Catch's Time Bandit, appears on the show and meets with Josh, Casey, and Jeff to help answer questions about Phil's possible motives on fishing in Hawaiian waters.
