Kinematic Effects on Schooling in Juvenile <i>Rachycentron canadum</i>
Shore, Sarah Katherine
Abstract: <i>Rachycentron canadum</i>, or cobia, are a large, fast-growing teleost fish commonly found in warm tropical waters including the waters of coastal Carolina. As juveniles, they have a strong affinity for schooling. Previous studies have shown that schooling position has an effect on the kinematics of fishes. In this study, juvenile cobia were placed in a flume in groups of four, and the effect of their position in the school on swimming performance was observed. Initial results show that there is not a significant difference between the amplitude and stroke frequency of the caudal fins in front, middle, or back positioned fish. However, swimming endurance at increasingly high flow rates may be contingent on the amount of time the cobia spend at the front of the school.
