Graysby fish

The graysby Cephalopholis cruentata, is the commonest sea bass in the Bahamas and despite its small size (1 fit) has some importance there as a food fish.

Other names for graysby fish are enjambre, cherna enjambre, cuna cabrilla.  A typical component in the shallow-water taro fishery, it is the third most abundant grouper in the Jamaican trap fishery.

Note the pale or dark spots, three to five in number, at the base of the dorsal fin. The tail is more rounded than similar appearing species.

It is typically found resting on the bottom, under ledges or near crevices in which to hide. They are all spotted like coneys and have similarity shaped body. As a result, graysbys are often confused with coneys.

Territories are shared by male and his harem of several females. A nocturnal predator on small fish, it feeds heavily on Brown Chromis. The graysby is a popular food fish. Juvenile are all females and transforms to males when about 20 cm in length.

Graysbys are considered to be common in shallow reef communities throughout their range, which extends form Bermuda to the middle of Brazil and includes the Gulf of Mexico.
