Captain Phil Harris suffered what his family described as a massive stroke on January 29th while the boat was in port at St. Paul Island, Alaska. He was flown to Anchorage for surgery.
A Discovery spokesman says the Harris family contacted the network Tuesday evening with word of his death.
Few details were released; however, Discovery Channel spokeswoman Elizabeth Hillman issued a statement on behalf of Harris' sons, Jake and Josh, saying their father has "always been a fighter and continued to be until the end."
The Discovery Channel reality show depicts the crab fishing industry in the dangerous waters off Alaska. Harris' fishing vessel was based in Seattle.
