  • The caudal fin, contributes to the forwards thrust against the water current.

  • The dorsal, anal and ventral fins control the rolling and yawing movements of the fish.
  • The pectoral and pelvic fins act as hydroplanes and control the pitch of the fish, causing it to swim downwards or upwards. The pectoral fins lie in front of the centre of gravity and, being readily mobile, are chiefly responsible for sending the fish up or down.
