  • Dispersal Patterns, Active Behaviour, and Flow Environment During Early Life History of Coastal Cold Water Fishes
    Dispersal Patterns, Active Behaviour, and Flow Environment during Early Life History of Coastal Cold Water Fishes Ryan Stanley1*, Paul V. R. Snelgrove1,2, Brad deYoung3, Robert S. Gregory4 1 Ocean Sciences Centre and Biology Department, Memorial University of Newfoundland, St. John’s, Newfoundland, Canada, 2 Canada Research Chair in Boreal and Cold Ocean Systems, Memorial University of Newfoundland, St. John’s, Newfoundland, Canada, 3 Department of Physics and Physical Oceanography, Memorial University of Newfoundland, St. John’s, Newfoundland, Canada, 4 Ecological Sciences Section and Centre of Expertise for Aquatic Habitat Research, Fisheries and Oceans Canada, St. John’s, Newfoundland, Canada Abstract During the pelagic larval phase, fish dispersal may be influenced passively by surface currents or actively determined by swimming behaviour. In situ observations of larval swimming are few given the constraints of field sampling. Active behaviour is therefore often inferred from spatial patterns in the field, laboratory studies, or hydrodynamic theory, but rarely are these approaches considered in concert. Ichthyoplankton survey data collected during 2004 and 2006 from coastal Newfoundland show that changes in spatial heterogeneity for multiple species do not conform to predictions based on passive transport. We evaluated the interaction of individual larvae with their environment by calculating Reynolds number as a function of ontogeny. Typically, larvae hatch into a viscous environment in which swimming is inefficient, and later grow into more efficient intermediate and inertial swimming environments. Swimming is therefore closely related to length, not only because of swimming capacity but also in how larvae experience viscosity. Six of eight species sampled demonstrated consistent changes in spatial patchiness and concomitant increases in spatial heterogeneity as they transitioned into more favourable hydrodynamic swimming environments, suggesting an active behavioural element to dispersal.

  • Hydrodynamics of Balistiform Swimming in the Picasso
    HYDRODYNAMICS OF BALISTIFORM SWIMMING IN THE PICASSO TRIGGERFISH, RHINECANTHUS ACULEATUS by HALE LOOFBOURROW BSc. University of British Columbia, 2006 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE in THE FACULTY OF GRADUATE STUDIES (Zoology) THE UNIVERSITY OF BRITISH COLUMBIA (VANCOUVER) January 2009 © Hale Loofbourrow, 2009 ii Abstract Aquatic propulsion by means of undulatory movements of the median (dorsal and anal) fins is the primary mode of transport for the Picasso triggerfish (Rhinecanthus aculeatus). Known as balistiform locomotion, this form of propulsion is an adaptation for highly efficient movement within complex environments such as coral reefs. A principle component of balistiform locomotion has been the development of momentum enhancement, a fin-force multiplier that increases swimming efficiency. This study examines the kinematics and energetics of balistiform locomotion employing theoretical models of thrust, power, and efficiency. Thrust and power were calculated and compared with theoretical values modeled by Lighthill and Blake (1990). This model has heretofore not been thoroughly vetted and was tested for accuracy and applicability. Thrust force was estimated from resistance (drag) using a vertical dead drop to determine terminal velocity; power was calculated from oxygen consumption measurements at different speeds. The Lighthill and Blake (1990) model requires median fin kinematics (frequency, wavelength, amplitude, wave angle), which were measured from high-speed videography and followed statistically predicted trends with frequency being the dominant variable, and the others changing little or not at all with speed. Momentum enhancement was found to be 3.6, close to Lighthill and Blake’s (1990) theoretically predicted value of 2.5.

  • Kinematics of Ribbonfin Locomotion in the Bowfin, Amia Calva
    RESEARCH ARTICLE Kinematics of Ribbon‐Fin Locomotion in the Bowfin, Amia calva 1,2 KEVIN JAGNANDAN * AND CHRISTOPHER P. SANFORD1 1Department of Biology, Hofstra University, Hempstead, New York 2Department of Evolution, Ecology and Organismal Biology, University of California, Riverside, California ABSTRACT An elongated dorsal and/or anal ribbon‐fin to produce forward and backward propulsion has independently evolved in several groups of fishes. In these fishes, fin ray movements along the fin generate a series of waves that drive propulsion. There are no published data on the use of the dorsal ribbon‐fin in the basal freshwater bowfin, Amia calva. In this study, frequency, amplitude, wavelength, and wave speed along the fin were measured in Amia swimming at different speeds (up to 1.0 body length/sec) to understand how the ribbon‐fin generates propulsion. These wave properties were analyzed to (1) determine whether regional specialization occurs along the ribbon‐ fin, and (2) to reveal how the undulatory waves are used to control swimming speed. Wave properties were also compared between swimming with sole use of the ribbon‐fin, and swimming with simultaneous use of the ribbon and pectoral fins. Statistical analysis of ribbon‐fin kinematics revealed no differences in kinematic patterns along the ribbon‐fin, and that forward propulsive speed in Amia is controlled by the frequency of the wave in the ribbon‐fin, irrespective of the contribution of the pectoral fin. This study is the first kinematic analysis of the ribbon‐fin in a basal fish and the model species for Amiiform locomotion, providing a basis for understanding ribbon‐fin locomotion among a broad range of teleosts.

  • Morphology and Experimental Hydrodynamics of Fish Fin Control Surfaces George V
    556 IEEE JOURNAL OF OCEANIC ENGINEERING, VOL. 29, NO. 3, JULY 2004 Morphology and Experimental Hydrodynamics of Fish Fin Control Surfaces George V. Lauder and Eliot G. Drucker Abstract—Over the past 520 million years, the process of evo- lution has produced a diversity of nearly 25 000 species of fish. This diversity includes thousands of different fin designs which are largely the product of natural selection for locomotor performance. Fish fins can be grouped into two major categories: median and paired fins. Fins are typically supported at their base by a series of segmentally arranged bony or cartilaginous elements, and fish have extensive muscular control over fin conformation. Recent experimental hydrodynamic investigation of fish fin func- tion in a diversity of freely swimming fish (including sharks, stur- geon, trout, sunfish, and surfperch) has demonstrated the role of fins in propulsion and maneuvering. Fish pectoral fins generate either separate or linked vortex rings during propulsion, and the lateral forces generated by pectoral fins are of similar magnitudes to thrust force during slow swimming. Yawing maneuvers involve differentiation of hydrodynamic function between left and right fins via vortex ring reorientation. Low-aspect ratio pectoral fins in Fig. 1.

  • The Effects of Viscosity on the Axial Motor Pattern and Kinematics of the African Lungfish (Protopterus Annectens) During Lateral Undulatory Swimming
    1612 The Journal of Experimental Biology 211, 1612-1622 Published by The Company of Biologists 2008 doi:10.1242/jeb.013029 The effects of viscosity on the axial motor pattern and kinematics of the African lungfish (Protopterus annectens) during lateral undulatory swimming Angela M. Horner* and Bruce C. Jayne Department of Biological Sciences, University of Cincinnati, PO Box 210006, Cincinnati, OH 45221-0006, USA *Author for correspondence at present address: Department of Biological Sciences, Ohio University, Irvine Hall, Athens, OH 45701, USA (e-mail: [email protected]) Accepted 7 March 2008 SUMMARY Separate studies of terrestrial and aquatic locomotion are abundant, but research addressing locomotion in transitional environments (e.g. mud) is scant. The African lungfish (Protopterus annectens) moves in a gradation of water to mud conditions during seasonal droughts, and breathes air. Thus, the lungfish was an ideal organism for our study to determine the effects of a wide range of viscosities on lateral undulatory swimming and to simulate some of the muddy conditions early tetrapods may have encountered. Regardless of viscosity, several aspects of lungfish swimming were similar to those of other swimming vertebrates including: posteriorly propagated muscle activity that was unilateral and alternated between the left and right sides at each longitudinal location, and posterior increases in the amount of bending, the amplitude of muscle activity and the timing differences between muscle activity and bending. With increased viscosity (1–1000·cSt), significant increases occurred in the amount of lateral bending of the vertebral column and the amplitude of muscle activity, particularly in the most anterior sites, but the distance the fish traveled per tail beat decreased.

  • Fish Locomotion: Biology and Robotics of Body and Fin-Based Movements
    Fish Locomotion: Biology and Robotics of Body and Fin-Based Movements George V. Lauder and James L. Tangorra Abstract The study of fish locomotion provides a rich source of inspiration for the design of robotic devices. Fish exhibit an array of complex locomotor designs that involve both diversity of structures used to generate locomotor forces, and versatile behaviors to engage with the aquatic environment. The functional design of fish includes both a flexible body exhibiting undulatory motion as well as numerous control surfaces that enable fish to vector forces and execute rapid maneuvers in roll, pitch, and yaw directions. Patterns of body undulation have often been misunderstood, and fish with propulsive mechanics as diverse as tuna and eels can display similar patterns of body bending during swimming. Many of the often-cited classical locomotor categories are based on a misunderstanding of body and fin kinematics. Fish fins can exhibit remarkably complex conformational changes during propulsion, and do not function as flat plates but have individual mobile fin rays actuated by muscles at the fin base. Fin motion and surface bending in most fish is actively controlled. Even during steady horizontal locomotion, median fins such as the dorsal and anal fins function to balance torques and can contribute to thrust. Locomotion using body undulation is not achieved independently from fin motion, and the vast majority of fish locomotor patterns utilize both the body and fins. Robotic systems derived from fish templates can range from simple flexible plastic panels to more complex models of whole body and fin design. Experimental test platforms that represent individual fins or specific components of fish locomotor design allow for detailed testing of hydrodynamic and mechanical function.
