... behavioral characteristic (boldness) impact the likelihood of an individual being captured by anglers. Largemouth bass, Micropterus salmoides , derived from a population artificially selected for differential angling vulnerability were assessed for boldness and for stress responsiveness (as indicated...

...Steven J. Cooke; David P. Philipp SUMMARY In this study, the cardiovascular response to exhaustive exercise among differentiated stocks of largemouth bass Micropterus salmoides was compared at 10°C and 20°C to assess the level of their local adaptation. In addition, the impact that interstock...

...Andrew M. Carroll SUMMARY Activation and strain in the sternohyoideus (SH) were measured in vivo in five largemouth bass Micropterus salmoides . The SH is thought to actuate lower jaw depression, hyoid depression and suspensorial abduction during suction feeding in teleost fish. Sonomicrometry...

... level it is clear that the expansion of the buccal cavity is responsible for the drop in pressure. However, attempts using high-speed video recordings to demonstrate a tight link between prey capture kinematics and suction pressure have met with limited success. In a study with largemouth bass...

...Tierney M. Thys; Jason M. Blank; David J. Coughlin; Fred Schachat SUMMARY The present study investigates muscle protein expression in largemouth bass Micropterus salmoides through intra- and intermyomeric comparisons of white muscle. Using denaturing SDS-polyacrylamide gel electrophoresis, muscle...

... ( Oncorhynchus mykiss ), electromyographic (EMG) and sonomicrometry recordings were made of muscle activity in vivo . These data were used in in vitro work-loop studies of muscle power production. Data on in vitro power production were also collected for largemouth bass ( Micropterus salmoides ) red muscle from...

... 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...

...Tierney Thys ABSTRACT Epaxial muscle activity during prey strike was measured in two discrete myomeric regions of the largemouth bass Micropterus salmoides to test whether (1) the extreme dorsal region of the epaxial muscle (the epaxial arm region) plays a larger role in prey strike than the region...

...Bruce C. Jayne; George V. Lauder ABSTRACT We analyzed midline kinematics and obtained electromyograms (EMGs) from the superficial red muscle at seven longitudinal positions in four largemouth bass swimming steadily at standardized speeds of 0.7, 1.2, 1.6, 2.0 and 2.4 lengths s -1 . Analysis...

...Peter C. Wainwright; Barton A. Richard ABSTRACT We present the first analysis of scaling effects on the motor pattern of a feeding vertebrate. Data are presented for the effects of body size on the pattern of activity in four head muscles during prey capture in the largemouth bass, Micropterus...

...Barton A. Richard; Peter C. Wainwright ABSTRACT We present the first analysis of scaling effects on prey capture kinematics of a feeding vertebrate. The scaling of feeding kinematics of largemouth bass ( Micropterus salmoides ) was investigated using high-speed video (200 fields s 1) to determine...

...Bruce C. Jayne; George V. Lauder ABSTRACT We used frame-by-frame analysis of high-speed videotapes to quantify midline kinematics during steady swimming in largemouth bass at five standardized speeds (0.7, 1.2, 1.6, 2.0 and 2.4 L s −1 , where L is total length). By combining morphological data from...

... that a hydromechanical stimulus detected by the cephalic lateral line system in two sunfishes (Centrarchidae) can be the sole determinant of a strike trajectory. The response occurs without reinforcement and appears to be an unconditioned response. Green sunfish ( Lepomis cyanellus Rafinesque) and largemouth bass...
