The orange-spotted grouper (Epinephelus coioides), also known as the brown-spotted rockcod, estuary cod, estuary rockcod, goldspotted rockcod, greasy cod, North-west groper, orange spotted cod or blue-and-yellow grouper, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses.

The spots are larger and less numerous in juveniles, shrinking in size and multiplying in number as the fish grows.

It is also found off Madagascar, Mauritius, and Réunion and in the Persian Gulf eastward into the Pacific Ocean as far as Palau and Fiji.

Off Papua New Guinea they have been reported to gather to spawn in aggregations of around 1,500 individuals and this takes place for 3–4 days each month over a muddy and sandy substrate.

They are mostly targeted using fish traps, and have spectacular tasting flesh[citation needed] which attains a high value in markets.

It has been assessed that they have been overexploited 7 times the normal level, and fisherman have described: "20 years ago, one net catches you 50kg.

[citation needed] The orange-spotted grouper was first formally described by the Scottish physician and naturalist Francis Buchanan-Hamilton (1762-1829) as Bola coioides in 1822 with the type locality given as the estuary of the Ganges.
