The energetic impact of overwinter prey assemblages on age-0 largemouth bass, Micropterus salmoides

The Effects of Acute Temperature Change on Prey Capture Kinematics in Largemouth Bass, Micropterus salmoides

The effects of temperature on prey capture kinematics were investigated in the Largemouth Bass, Micropterus salmoides. Five individuals were first acclimated to 22 C and then acutely exposed to temperatures of 15, 20, 25, and 30 C. At each temperature, feeding events were recorded using high-speed video at 500 frames s. An analysis of variance on the five fastest feeding events from each indivi...

Survival of Foul-Hooked Largemouth Bass(Micropterus salmoides)

We conducted a field experiment to determine the survival rate of foul-hooked (hooked external to the oral cavity) largemouth bass (Micropterus salmoides) caught and released by recreational anglers. Of 42 largemouth bass caught with hard-plastic baits containing three treble hooks, 15 were hooked only within the mouth and 27 had at least one hook penetrating the external surface of the fish (i...

Scaling the feeding mechanism of largemouth bass (Micropterus salmoides): kinematics of prey capture

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 what functional changes occur in the feeding mechanism as a consequence of body size. A size series of ten bass ranging from 32 to 210 mm standard le...

Food chain transfer of perchlorate in largemouth bass, Micropterus salmoides.

Influence of local adaptation and interstock hybridization on the cardiovascular performance of largemouth bass Micropterus salmoides.

In this study, the cardiovascular response to exhaustive exercise among differentiated stocks of largemouth bass Micropterus salmoides was compared at 10 degrees C and 20 degrees C to assess the level of their local adaptation. In addition, the impact that interstock hybridization had on adaptive differences was assessed using F1 hybrids. To accomplish these assessments, four genetically distin...
