Abstract

The few existing measurements of deep-sea fish physiology consistently indicate reduced basal metabolism and metabolic power. A possible explanation for this is the reduction in selective pressure for burst activity capacity due to a reduction in the frequency and duration of predator-prey interactions in the sparsely distributed fish community and continuous darkness. Video recordings of stimulated fast-starts in deep-sea fish were obtained by a lander vehicle and analysed to give the swimming velocities, accelerations, and inertial power requirements of fast-start swimming in Antimora rostrata. With a mean peak velocity of 0.7 m s(-1), and white muscle power output of only 17.0 W kg(-1). A. rostrata is a slow moving fish, but no slower than shallow-water fishes at the same temperature.
