features
White sea bass have an elongated, spindle-shaped, laterally compressed body. They usually reach about one meter, a maximum of 166 centimeters in length and a weight of up to 41 kilograms. The back is blue to copper-colored with dark spots, the belly is silver-colored. Young animals have three to six dark stripes on their backs and dark yellowish fins. The scales are small and rough except around the eye. The mouth is at the end with a slightly protruding lower jaw and slightly hanging angles that reach below the end of the eye. The teeth are in several rows. There are no barbels . The dorsal fin has ten to eleven hard rays in the first part, and 19 to 23 soft rays in the second part, separated by a deep notch. The caudal fin ends straight or slightly concave. The pectoral fins have a dark spot on the inside and a fleshy appendage at their base. Like the pelvic fins, they are short. The anal fin has two hard rays, the first of which is about twice as long as the second, and eight or nine soft rays. The gill trap has 13 to 18 thorns.
Way of life
White sea bass are predatory fish that feed on other fish, cephalopods, and crustaceans. They live in schools over rocky or algae-covered ground near reefs near the coast and estuaries. The eggs are released into the open water from March to October. The young animals stay in bays and in front of sandy beaches.
