Migratory behaviour and habitat use by American eels Anguilla rostrata as revealed by otolith microchemistry
TLDR
Four distinct but interrelated behavioural groups were identified by the temporal changes in Sr:Ca ratios in their otoliths: (1) entrance into freshwater as an elver, (2) coastal or estuarine residence for 1y r or more before entering freshwater, and, after enteringfresh, (3) continuous freshwater res- idence until the silver eel stage.

Variation 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 variableExpand
Geographic effects on American eel (Anguilla rostrata) life history characteristics and strategies
Latitudinal variability in length and age at maturity and annual growth rate for the American eel (Anguilla rostrata) along the Atlantic coast of North America was examined with respect to lifeExpand
Is there a role of ocean environment in American and European eel decline
TLDR
While specific causes are still unclear, these data indicate a threat to both species and to their commercial fisheries. Expand
Migrating American Eels in Nova Scotia
TLDR
Silver eels migrating later in the run were more mature (had higher gonadosomatic indices) than those migrating earlier, and mean lengths and weights of downstream-migrating American eels differed among rivers, increasing as the run progressed from late August to mid-November. Expand
Distribution and Timing of Tag Recoveries from Native and Nonnative Atlantic Salmon (Salmo salar) Released into Big Salmon River, New Brunswick
Recaptures of tagged Atlantic salmon (Salmo salar) released as smolts into the Big Salmon River varied between annual releases with no differences found on the basis of native or nonnative origin.Expand
Estimates of Population Size and Instream Mortality Rate of American Eel Elvers in a Nova Scotia River
Abstract The recruitment of American eel Anguilla rostrata elvers to the East River, Chester, Nova Scotia, during May through July was estimated by trap (Irish type) counts at 209,190 elvers and byExpand
Geographic and seasonal variation in biological characteristics of American eel elvers in the Bay of fundy area and on the Atlantic coast of Nova Scotia
Seasonal (April-July) patterns in the decline of length, mass, and condition and an increase in pigmentation stage of American eel (Anguilla rostrata) elvers collected during the estuarine commercialExpand
Fecundity of Anadromous Alewives and Blueback Herring in New Brunswick and Nova Scotia
Abstract Fecundity, ovary weight, and egg weights, adjusted for fish length, of anadromous alewives Alosa pseudoharengus and blueback herring A. aestivalis differed among some of four MaritimeExpand
Life history of American eel Anguilla rostrata: new insights from otolith microchemistry
TLDR
Development of a simple, comprehensive residence and inter-habitat migration classification scheme would greatly assist the interpretation and comparison of otolith microchemistry studies and highlight the importance of brackish and marine waters as areas of eel production. Expand
