...Eric D. Tytell SUMMARY Simultaneous swimming kinematics and hydrodynamics are presented for American eels, Anguilla rostrata , swimming at speeds from 0.5 to 2 L s -1 . Body outlines and particle image velocimetry (PIV)data were collected using two synchronized high-speed cameras, and an empirical...

...Eric D. Tytell; George V. Lauder SUMMARY Eels undulate a larger portion of their bodies while swimming than many other fishes, but the hydrodynamic consequences of this swimming mode are poorly understood. In this study, we examine in detail the hydrodynamics of American eels ( Anguilla rostrata...

...Gary B. Gillis ABSTRACT Eels ( Anguilla rostrata ) are known to make occasional transitory excursions into the terrestrial environment. While on land, their locomotor kinematics deviate drastically from that observed during swimming. In this study, electromyographic (EMG) recordings were made from...

... + /K + -ATPase activity. An enriched preparation of basolateral membranes was prepared from the gills of freshwater- and seawater-acclimated American eel ( Anguilla rostrata ). Phospholipid class distribution, fatty acyl chain compositions and cholesterol contents were determined. Phosphatidylcholine...

... trout ( Oncorhynchus mykiss ) and American eel ( Anguilla rostrata ). In trout, bolus injections of homologous [Asn 1 ,Val 5 ]-Ang II (100 or 500 pmol kg −1 ) increased catecholamine secretion rates and plasma catecholamine concentrations from in situ posterior cardinal vein preparations and chronically...

... electromyographic data from red and white muscle at four positions, 0.3 L , 0.45 L , 0.6 L and 0.75 L , where L is body length, in eels ( Anguilla rostrata ) simultaneously video- taped (250 fields s −1 ) swimming at three speeds, 0.5, 0.75 and 1.0 L s −1 . As in other fish, exclusively red muscle is used at slow...

... the kinematic patterns of undulatory locomotion in water and on land in the American eel Anguilla rostrata . During swimming, eels show a nonlinear increase in the amplitude of lateral undulations along their bodies, reaching an average maximum of 0.08 L , where L is total length, at the tip of the tail...

...Kenneth J. Rodnick; John R. Bailey; Jenny L. West; Alison Rideout; William R. Driedzic ABSTRACT We investigated the effects of anoxia and contractile activity on glucose uptake and the intracellular location of hexokinase in cardiac muscle of the American eel Anguilla rostrata . Uptake of 2...

...José L. Soengas; Thomas W. Moon ABSTRACT The uptake and metabolism of glucose, alanine and lactate were assessed in red blood cells (RBCs) of the American eel Anguilla rostrata . L-Lactate was metabolized at the highest rates as assessed by O 2 consumption and CO 2 production, followed by glucose...

...Steve F. Perry; Scott D. Reid ABSTRACT Experiments were performed in vitro specifically to elucidate the underlying mechanism(s) of the attenuated adrenergic responses of eel (Anguilla rostrata) erythrocytes. This was achieved by comparing β -adrenoceptor numbers and affinities in addition to (i...

...D. A. Hyde; S. F. Perry ABSTRACT The involvement of the gill and kidney in acid-base regulation was examined in the American eel, Anguilla rostrata , during 36h of continuous air-exposure and subsequent return to water. While in air, eels developed a severe mixed respiratory/-metabolic acidosis...
