McGlashan was 33.
No cause of death or further information has been given and his death is currently under investigation.
Discovery, the home of its series, has released a statement to CNN.
“Our deepest condolences go to Nick’s loved ones at this difficult time,” the statement read. “Nick came from a long line of crabbers and was known for his great knowledge. He also had a keen sense of humor, even in the most difficult of circumstances. He will be deeply missed by everyone who knew him.”
The show chronicles the lives of crews working on fishing vessels in the Bering Sea.
Born in Alaska to the son of an accomplished commercial fisherman, McGlashan started working on a boat when he was 13 years old.
“It is named after his great-uncle Nick McGlashan, who worked on the first boat said to be a pioneer in the American crab industry, the F / V Deep Sea, built in 1947,” the bio reads. “Two of Nick’s aunts were also crabbers; one of them was lost at sea when the boat sank in 1986.”
McGlashan worked as the boss on “Deadliest Catch” and has appeared on the series since 2013.
McGlashan wrote that he had abused alcohol, heroin and methamphetamine and overdosed three times before entering treatment and sobering in September 2016.
“My life went from Beringzee badass to full-blown junkie very quickly. Hidden from me was that passion I had for life,” he wrote. “Taken from me was my ability to live. I was at war with my addiction and that was winning.”
McGlashan was kicked off the boat for a while during Season 13 to deal with his addiction.
“Although he has had his ups and downs, Nick has struggled endlessly to stay sober and embrace a new down-to-earth lifestyle. He is now so committed to his recovery that he inspires others in their own countries,” said his Discovery Go biography .
