Movement patterns of American eels (Anguilla rostrata) between salt- and freshwater in a coastal watershed, based on otolith microchemistry
Abstract Otolith strontium:calcium ratios were used to trace lifetime movements of American eels (Anguilla rostrata) captured in salt-water bays and adjoining freshwater ponds in Prince Edward Island, Canada. Eels were classiWed into migratory contingents based on their movement patterns. A pond with a pool-and-weir salmonid Wshway and a pond drained by a low-gradient channel contained eels tha...
متن کاملKinematics and hydrodynamics of linear acceleration in eels, Anguilla rostrata.
The kinematics and hydrodynamics of routine linear accelerations were studied in American eels, Anguilla rostrata, using high-speed video and particle image velocimetry. Eels were examined both during steady swimming at speeds from 0.6 to 1.9 body lengths (L) per second and during accelerations from -1.4 to 1.3 L s(-2). Multiple regression of the acceleration and steady swimming speed on the bo...
متن کاملHow does salinity influence habitat selection and growth in juvenile American eels Anguilla rostrata?
The influence of salinity on habitat selection and growth in juvenile American eels Anguilla rostrata captured in four rivers across eastern Canada was assessed in controlled experiments in 2011 and 2012. Glass eels were first categorized according to their salinity preferences towards fresh (FW), salt (SW) or brackish water (BW) and the growth rate of each group of elvers was subsequently moni...
متن کاملPrevalence and intensity of occurrence of vaterite inclusions in aragonite otoliths of American eels Anguilla rostrata
The presence of vaterite mosaic in the aragonite otoliths of anguillid eel otoliths is readily determined by reflected light microscopy after etching with EDTA. The prevalence and intensity of vaterite inclusions in sagittal otoliths of 165 American eels Anguilla rostrata were examined in relation to latitude and migratory history. Prevalence varied significantly (range: 21.3 to 58.8%) among 3 ...
متن کاملVariation in the annual growth, by sex and migration history, of silver American eels Anguilla rostrata
Silver American eels Anguilla rostrata from the East River, Chester, on the Atlantic coast of Nova Scotia, as evaluated by the temporal pattern of Sr:Ca ratios in their otoliths, showed variable patterns of migration between river and estuarine/marine waters during their yellow eel stage. Eels with a history of primarily estuarine residence were longer (total length) at migration and had higher...
