7 Biggest Goliath Groupers Ever Recorded

171-Pound Potato Grouper

This 171 lb, 10 ounce potato grouper became the pride and joy of one Takayuki Shibayama. On the 11th of June, 2004, Takayuki was fishing along the waters off Miyako Island located in the prefecture of Okinawa in southern Japan. To capture this behemoth of a fish, Shibayama used a snapper fish to haul in this giant grouper. The happy fisherman is shown with a wide smile beside his catch of the day.
