Deadliest Catch's Captain Phil Harris died in Alaska Tuesday night. He was 53.
Harris -- who starred on the Discovery Channel reality show for five seasons -- suffered a massive stroke last month.
"It is with great sadness that we say goodbye to our dad, Captain Phil Harris," said his sons, Josh and Jake, in a statement. "Dad has always been a fighter and continued to be until the end. For us and the crew, he was someone who never backed down. We will remember and celebrate that strength. Thanks to everyone for their thoughts and prayers."
The network released a statement, "Discovery mourns the loss of dear friend and colleague Captain Phil Harris. He was more than someone on our television screen. Phil was a devoted father and loyal friend to all who knew him. We will miss his straightforward honesty, wicked sense of humor and enormous heart. We share our tremendous sadness over this loss with the millions of viewers who followed Phil's every move. We send our thoughts and prayers to Phil's sons Josh and Jake and the Cornelia Marie crew.
Harris seemed to be on the mend after undergoing surgery in January. On Saturday, he reality star posted on his Web site that he was "talking to friends and family today; showing his greatest progress" since suffering from the stroke.
