This 360-pound goliath grouper was caught around 1910. Juniper Inlet in Florida, where it was found, is now a protected nesting ground for grouper. See more amazing catches from way back in the day, when fish were this big and men made sure there was a photographic record of it, in the post Early 20th-Century Fishing Photographs from Florida at Environmental Graffiti.
