Hemicaranx bicolor (Günther); Bicolor jack Remarks: Hemicaranx bicolor, synonymized with Caranx bicolor (Günther), was a common catch across all our sampling locations. This species is distributed in marine and brackish waters, ranging from Senegal through the Gulf of Guinea to Angola. Hemicaranx bicolor is characterized by a moderately elongated, deep, and strongly compressed body, with a bluntly rounded snout and a small eye. The dorsal body coloration is dark blue green, transitioning to a silvery hue ventrally. Other notable features include a prominent black blotch on the operculum and black coloration along the dorsal-fin margin and tips of the upper caudal-fin lobe.
