... to predators. In this paper, we present an experimental hydrodynamic analysis of the C-start escape response in bluegill sunfish ( Lepomis macrochirus ). We used time-resolved digital particle image velocimetry at 1000 frames s –1 (fps)to image flow patterns during the escape response. We analyzed flow...

... of this study were to directly measure forces exerted by bluegill Lepomis macrochirus on their prey and to determine how bluegill modify force output. Bluegill were offered ghost shrimp tethered to a load cell that recorded force at 5000 Hz, and feeding sequences were synchronously recorded using 500 Hz video...

... to Anguilla rostrata and three perciform species: the North American centrarchids, Lepomis macrochirus (Rafinesque) and Micropterus salmoides (Lacépède), and the Central American cichlid, Amphilophus citrinellus (Günther). Both L. macrochirus and M. salmoides have been the focus of many studies...

...-dimensional volumetric flow measurements are not currently feasible, but measurements in multiple transverse planes along the body can illuminate many of the important flow features. In this study, I analyze flow in the transverse plane at a range of positions around bluegill sunfish Lepomis macrochirus...

..., because most fish protract these structures as they decelerate. However, the kinematics and modulation of velocity during starting and stopping are poorly understood for most species of fish as well as most species of animals. Thus,for bluegill sunfish Lepomis macrochirus with complete and partially...

...,particularly the temporal and spatial patterns of water velocity in front of the fish. To characterize the flow in front of suction-feeding bluegill sunfish Lepomis macrochirus , measurements with high spatial (<1 mm) and temporal (500 Hz) resolution were taken using Particle Image Velocimetry (PIV...

... the effects of ram on the maximum fluid speed of the water entering the mouth during feeding as well as the spatial patterns of flow entering the mouth of suction-feeding bluegill sunfish Lepomis macrochirus . Using Digital Particle Image Velocimetry (DPIV) and high-speed video, we observed the flow in front...

... locomotor dynamics. In this paper, we measure the fluid forces exerted by the left and right pectoral fins of bluegill sunfish ( Lepomis macrochirus ) during turning using digital particle image velocimetry (DPIV). DPIV allowed quantification of water velocity fields, and hence momentum, in the wake...

... to determine how hydrodynamic force varies in two species that differ markedly in maximum swimming speed. Black surfperch ( Embiotoca jacksoni ) and bluegill sunfish ( Lepomis macrochirus ) swim at low speeds using their pectoral fins exclusively, and at higher speeds switch to combined pectoral and caudal fin...

... of T o and T c in three centrarchid fishes. Video recordings (200 and 400 images s −1 ) were made of prey capture in largemouth bass Micropterus salmoides (33–206 mm standard length, SL ), spotted sunfish Lepomis punctatus (24–145 mm SL ) and bluegill sunfish Lepomis macrochirus (24–220 mm SL...

... (DPIV), it is possible to quantify the effect of fish fins on water movement and hence to estimate momentum transfer from the animal to the fluid. We used DPIV to visualize water flow in the wake of the pectoral fins of bluegill sunfish ( Lepomis macrochirus ) swimming at speeds of 0.5–1.5 L s −1...

... prey capture and transport kinematics in a ray-finned fish ( Lepomis macrochirus , the bluegill sunfish) to examine the generality of differences between capture and transport behaviors in aquatic vertebrates. Compared with prey capture, prey transport is significantly more rapid and tends to have...

... to examine the movements of different portions of pectoral fins, we quantified the kinematics of pectoral fin locomotion in the bluegill sunfish Lepomis macrochirus using several points on the distal fin edge and examined the effects of swimming speed on fin movements. We simultaneously videotaped...

...Paul W. Webb ABSTRACT Deep-bodied fish, such as the bluegill sunfish (Lepomis macrochirus) , are considered to have relatively larger wetted surface areas for their size than fusiform fish. On the basis of the boundary layer thinning hypothesis attributing high power requirements of undulatory...
