According to his bio on Discovery Go, McGlashan was a 7th generation fisherman, raised on the island of Akutan, Alaska, not far from Dutch Harbor — the base of operations on Deadliest Catch.

McGlashan was named after his great uncle, who "worked on the first boat rumored to have pioneered the U.S. crab industry, the Deep Sea, built in 1947."

The deck boss first began crabbing when he was 13-years-old, joining his family on his dad's boat, the Westling, which they took out on the Bering Sea.

McGlashan's father, Bruce, and Wild Bill had been longtime friends, so McGlashan started working for him on the Kodiak in 2011. After quickly earning Bill's respect, McGlashan was appointed to head the crew on Cape Caution and later Summer Bay.

"Nick is known for his witty quips, working through the pain, and not stopping the job until it's done. He has also kept the boat running through all kinds of mechanical issues, manufacturing quick fixes on the fly," his Discovery bio reads. "Nick has a wealth of fishing experience and, according to Captain Bill, is the epitome of a true crabber."

However, McGlashan struggled with alcohol and drug addiction in the past, which got him suspended from season 13. He eventually went to rehab and had "battled endlessly to stay sober and embrace a new sober lifestyle and is now so committed to his recovery that he inspires others in their own."

Deadliest Catch has a history of tragedy, with several cast members dying over the years. In August, the show lost deckhand Mahlon Reyes, who was 38 at the time.
