WATCH: Couple catches 300 pound goliath grouper on Florida beach

What would Jonah think of that?

Beachgoers saw quite the spectacle on Sanibel Island, Florida early Wednesday morning.

A couple fishing on the shoreline caught a goliath grouper that was estimated to be around 135 kilograms.

Onlookers photographed and filmed as the couple struggled to pull in the fish to shore to get a better look at it.

Graciela Mahana witnessed the catch and told CBS affiliate WINK News the ordeal took about an hour.

Another witness and fisherman Taylor Buckley said it is rare for such a catch to occur from shore.

“You would never expect that in a surf situation,” he said. “You don’t catch fish like that by casting into the surf.”

According to the Florida Fish and Wildlife Conservation, it is illegal to harvest goliath grouper. It is also recommended that the fish be left in the water for a photo because the fish cannot adequately support their weight outside of water.

Buckley said bystanders suggested that they all enjoy the grouper for lunch but the couple refused and released the fish.
