The orange-spotted grouper (Epinephelus coioides), also known as the estuary cod, estuary rockcod, estuary rock-cod, green grouper is a species of fish in the family Serranidae. It is found in the western Pacific, the Indian Ocean, and the Red Sea. It has also been recorded in the Mediterranean Sea as a Lessepsian migrant. Orange-spotted grouper is an economically important marine fish cultured Southeast Asian countries.
Orange-spotted groupers begin life as a female, reaching sexual maturity at around 2 to 3 years old, when 25 to 30 centimetres in length. When the female reaches around 55 to 75 centimetres, at approximately four years old, it changes sex and becomes a male.
Its natural habitats are subtropical or tropical mangrove, open seas, shallow seas, subtidal aquatic beds, coral reefs, estuarine waters, intertidal flats, and coastal saline lagoons. It is threatened by habitat loss and overfishing. This predatory fish reaches up to 1.2 m (3.9 ft) in length.
Anglers call Red Emperor Snapper by many names, including Red Snapper (not to be confused with this Red Snapper species), Emperor Snapper, Queenfish, Redfish, Red Kelp, Seba’s Snapper, and Government Bream. While it shares some of these names with other species, the Red Emperor is unmistakably unique in his appearance. Young fish are distinguished by three dark red bands that wrap around their bodies; as these fish age, all their scales turn a pink-red hue.
Red Emperor typically grow to 60 cm in length, and are known to grow as large as 116 cm on occasion. The largest fish of this kind credited by the IGFA so far was a 39 lb 7 oz Emperor caught off the coast of Tokyo, Japan.
When and Where
Red Emperor is native to the Indian and western Pacific Oceans, from northern Australia to southern Japan and east to the Red Sea. Despite its name, this fish is a Snapper species and bears little-to-no relation to other Emperor fish.
Red Emperors swim in water anywhere from 5-180 m deep. They live near inshore reefs when they’re young and then move offshore, typically inhabiting sandy flat areas near reefs.
