Yellowfin Croaker Identification Guide

Key identification features

• Slender, silvery body crossed by 12-15 diagonal, wavy bronze-to-brassy stripes running from back toward belly
• One short, thin barbel at the tip of the lower jaw, easily missed unless you look closely under the chin
• Yellow-tinged pelvic, anal, and lower caudal fins, the source of the common name
• Small, slightly subterminal mouth set beneath a blunt, rounded snout
• Moderately compressed body, usually 10-16 inches long, with a fairly pointed dorsal fin lacking any dark blotch
• Overall silvery base color that can flash coppery or brassy tones in bright sun, especially along the upper back

Common look-alikes

• Spotfin croaker: body lacks diagonal stripes but carries a bold black spot at the pectoral fin base and no yellow fin wash
• California corbina: uniform slate-gray back with no striping, a single longer barbel, and a more slender build overall
• Queenfish: no chin barbel at all, a more deeply forked tail, and plain unmarked silvery sides with a larger eye

Where you'll see one

Common in the surf zone, shallow sandy bays, and along piers of southern California and Baja California, often schooling just beyond the breaking waves over clean sand bottoms where they root for small invertebrates.
