Gerres nigri

The Guinean striped mojarra grows to a maximum length of 20 cm (8 in) and has a compact, laterally compressed body. The snout is short, the nostrils close together and the mouth protrusible. The dorsal fin is deeply notched and has nine spines and ten soft rays, while the anal fin has three spines and eight soft rays. The pectoral fin is long, extending to beyond the origin of the anal fin. The back of the fish is olive-brown and the flanks silvery, with longitudinal dark banding. Juveniles have two longitudinal rows of black spots on the dorsal fins and some dark barring on the sides.[3]

The Guinean striped mojarra is a coastal fish and is native to the tropical eastern Atlantic Ocean, its range extending from Senegal to northern Angola, including around the islands in the Gulf of Guinea at depths down to about 60 m (200 ft). It is a benthopelagic species forming schools and feeding near the seabed, where it favours sandy or muddy substrates. It is found in estuaries and lagoons and can tolerate a wide range of salinities, anything from 25 to 75 ppt.[1]

This fish is the subject of small scale and artisanal fisheries throughout its range. It is caught by trawling, bottom nets and line gear, and is eaten fresh or dried, seldom being made into fishmeal. It is a common fish throughout its range, and although it may be affected by overfishing, coastal development and water pollution in places, the International Union for Conservation of Nature has assessed its overall conservation status as being of "least concern".[1]
