Talk about the catch of a lifetime

A fisherman in South Carolina recently reeled in a Goliath Grouper that he estimated weighed up to 400 pounds. 

On Thursday, Tallboy Fishing Charters posted a video of the huge fish being reeled in on Facebook. According to WJCL, the charter was fishing off the coast of Hilton Head Island and the charter’s Richard Pollitzer filmed the clip.

"It didn’t act like a shark but I couldn’t imagine it would be anything else," the post said. "It was the last thing I expected to see come up after an hour fight."

"I’m estimating the weight to be in the vicinity of 400lbs?" the post continued. "Of course having never caught one or even seen one I may be off a little. Wow. I’m still in disbelief. Needless to say it put wind in Adam and I’s sails to keep on pushing."

According to the National Oceanic and Atmospheric Administration (NOAA), Goliath Groupers can weigh up to 800 pounds. 

The species has been banned from being harvested in waters off the southeast U.S. coast since 1990. If a Goliath Grouper is caught, it must be released.

The fish was nominated to be considered an endangered species in 1991 and was listed as a "species of concern" later, NOAA said. 

In 2006, Goliath Groupers were removed from the species of concern list, but they remain banned for harvest.
