Caranx fischeri (Smith-Vaniz & Carpenter) ;

Longfin crevalle jack

( Figure 2C )

Remarks: During our field study, C. fischeri was occasionally captured in Badagry and Epe, and rarely encountered in Ikorodu. This species is widely distributed across marine, freshwater, and brackish environments in the Eastern Atlantic, including the Mediterranean Sea. Caranx fischeri is characterized by its elongated, deep, and moderately compressed body, with a prominent eye. It has a first dorsal fin with eight spines and a second dorsal fin with a single spine and 21 soft rays. The dorsal side of its body exhibits a bluish-black coloration, transitioning to a golden hue ventrally. A distinctive oval black spot is present on the lower half of the pectoral fins, and the anal-fin lobe is predominantly white.
