Sucking while swimming: evaluating the effects of ram speed on suction generation in bluegill sunfish Lepomis macrochirus using digital particle image velocimetry
... It is well established that suction feeding fish use a variable amount of swimming (ram) during prey capture. However, the fluid mechanical effects of ram on suction feeding are not well established. In this study we ...

Caudal fin shape modulation and control during acceleration, braking and backing maneuvers in bluegill sunfish, Lepomis macrochirus
... ( Lepomis macrochirus ) through examination of the kinematics of the caudal fin and activity of the intrinsic caudal musculature during a diversity of unsteady locomotor behaviors: kick-and-glide swimming, ...

Morphological basis of kinematic diversity in feeding sunfishes
... we expressed predictions of the scaling of prey-capture kinematics in the two sunfish species relative to patterns observed in the largemouth bass. We selected the largemouth bass as the starting point for our ...

Hydrodynamics of linear acceleration in bluegill sunfish, Lepomis macrochirus
... In their natural habitat, fish rarely swim steadily. Instead they frequently accelerate and decelerate. Relatively little is known about how fish produce extra force for acceleration in routine swimming behavior. In this ...

UNDULATORY SWIMMING: HOW TRAVELING WAVES ARE PRODUCED AND MODULATED IN SUNFISH (LEPOMIS GIBBOSUS)
... At first it is surprising that a simple, alternating contraction of the lateral muscle, which is not characteristic of the EMG patterns in live fish (Williams et al. 1989; Van Leeuwen et al. 1990), produces undulatory ...

Energetic limitations on suction feeding performance in centrarchid fishes
... Energetic analysis of ecologically relevant behaviors can be useful because animals are energetically limited by available muscle mass. In this study we hypothesized that two major determinants of suction feeding ...

Streamwise vortices destabilize swimming bluegill sunfish (Lepomis macrochirus)
... Lacey et al. (2012) suggested that some of the diversity in the results could be organized by considering the intensity, periodicity, orientation and size of vortices in a wake, which they termed the ‘ IPOS ’ (intensity, ...

Constraints on starting and stopping: behavior compensates for reduced pectoral fin area during braking of the bluegill sunfish Lepomis macrochirus
... sunfish Lepomis macrochirus with complete and partially ablated pectoral fins (35% original fin area), we analyzed high speed video recordings (200·images·s –1 ) of predatory attacks with a start and stop ...

Speed dependent intrinsic caudal fin muscle recruitment during steady swimming in bluegill sunfish, Lepomis macrochirus
... ( Lepomis macrochirus ) were anaesthetized and electrode wires surgically placed into a total of 24 intrinsic caudal muscles, up to 13 at a time, and activity was correlated with synchronous recordings from ...

Fin ray sensation participates in the generation of normal fin movement in the hovering behavior of the bluegill sunfish (Lepomis macrochirus)
... ( Lepomis macrochirus Rafinesque 1819), afferent nerves in the fin rays and membrane can convey proprioceptive feedback that reflects fin ray position and velocity at frequencies and bend amplitudes ...

Parental care compromises feeding in the pumpkinseed fish (Lepomis gibbosus)
... effects of restricted ration will tend to be buffered by a larger body size (Wootton 1998). In smaller males, however, the effects of food limitation may be substantial due to greater relative energy expenditure on ...

Effect of Transient Acid Spikes on Developmental Stages of Lepomis Fishes
... Studies in our lab employing age-analysis of sagittal otoliths and environmen- tal data loggers have linked abnormalities in age structure of Lepomis sunfishes in Massachusetts ponds to poor buffering capacity ...

ULTRAVIOLET PHOTORECEPTION CONTRIBUTES TO PREY SEARCH BEHAVIOUR IN TWO SPECIES OF ZOOPLANKTIVOROUS FISHES
... We tested the hypothesis that ultraviolet photoreception contributes to prey search in small juvenile rainbow trout (Oncorhynchus mykiss) and pumpkinseed sunfish (Lepomis gibbosus) while foraging on Daphnia pulex. ...

Median fin function during the escape response of bluegill sunfish (Lepomis macrochirus) II: Fin ray curvature
... Three-dimensional (3-D) kinematic analysis of the rays and spines of the dorsal and anal fins revealed variation in movement and orientation based on position within the fin, suggesting that different regions of the fins ...
