Jewfish


Jewfish - In Brunei Darussalam, it is known as Keratang. Huge grouper with length of 8 feet (2.4 m) to 12 ft (3.7 m) & weight of 680 lb (310 kg) to 1,100 lb (500 kg) or more!
185 kg! - Awang Zailan, Brunei Darusalam sea zone

Despite its size, it lives in shallow water, usually no deeper than 100 ft (30 m) around rocky ledges, wrecks, & pilings. Not a hard fighter but its bad habit is to bolting into a hole when hooked, make it difficult to land!
