Bass Dicentrarhus labrax

British Marine Life Study Society   Information Page


A pelagic, or open water, fish like the predatory Bass uses its greater speed to capture smaller fish and prawns. Its method of swimming is worth looking at closely in Public Aquaria. At the start of a burst the head seems to align at an angle and with a pronounced undulation of the caudal peduncle (body in front of the tail fin) and with two or more flicks of the tail fin, the fish swims strongly forward. At speed the other fins are clamped down, but as soon as it brakes the spiny dorsal fin rises to maintain stability.
