“…Rather, effective management of mixed-stock populations requires a finer-scale approach that considers how stocks differentially contribute individuals according to local processes. This type of approach, however, requires the ability to identify the origins of individual fish, which historically has proven difficult in both marine and freshwater systems (Wolfert and Van Meter 1978;.…”

We evaluated otolith chemistry as a tool for identifying natal origins of potamodromous fishes using historical Lake Erie water chemistry (1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001) and yellow perch (Perca flavescens) otolith elemental composition (1994)(1995)(1996) data. Lake Erie's tributaries had stream-specific chemical signatures that were temporally stable. Correspondingly, the otolith microelemental composition of larvae collected from tributary embayments (Sandusky and Maumee bays) was shown to be geographically distinct and the use of known-origin juveniles showed that larval otolith microelemental signatures could be used to accurately identify natal origins and indicate fish movement. Discrimination between offshore spawning locations was relatively difficult, however, indicating limitations to working in systems that are dominated by flow from a single large river (i.e., Detroit River). Interannual variability in otolith microelemental signatures was high such that larvae from one year could not reliably classify natal location of larvae in another year. Development of an annual library of site-specific signatures and exploration of complementary ways to discriminate natal origins would improve the use of otolith microchemistry as a fishery management tool in freshwater systems.Résumé : Nous évaluons la chimie des otolithes comme outil d'identification des origines à la naissance des poissons potamodromes en utilisant des données de la chimie de l'eau du lac É rié du passé (1983-2001) et de la composition en élé-ments des otolithes (1994)(1995)(1996) de perchaudes (Perca flavescens). Les tributaires du lac É rié possédaient des signatures chimiques spécifiques à chacun qui étaient stables dans le temps. De même, les compositions des otolithes en microélé-ments des larves récoltées dans les baies associées aux tributaires (baies Sandusky et Maumee) étaient géographiquement distinctes; l'utilisation de jeunes d'origine connue a montré que les signatures en microéléments des otolithes des larves pouvaient servir à identifier avec précision les origines à la naissance et décrire les déplacements des poissons. Cependant, la discrimination entre les différents sites de fraie au large était relativement difficile, ce qui indique les limites qu'il y a à travailler dans des systèmes qui sont dominés par le débit d'une seule grande rivière (c'est-à-dire la rivière Détroit). La variabilité interannuelle dans les signatures des otolithes en microéléments était élevée si bien que les larves d'une année ne pouvaient servir à classifier de manière fiable les sites de naissance des larves d'une autre année. La mise au point de ré-pertoires annuels de signatures spécifiques au site et l'exploration de méthodes complémentaires pour distinguer les points d'origine à la naissance pourraient améliorer l'utilisation de la microchimie des otolithes comme outil de gestion des pê-ches dans les systèmes d'eau douce.[Traduit par la Rédaction]

“…Walleye mature at age 2-3 in Lake Erie (Wolfert 1963) and spawn at night in small groups shortly after the ice breaks up in spring, with females depositing their eggs in a single night and males staying on the spawning grounds for up to several weeks (Scott and Crossman 1973). Some walleye groups spawn in specific tributary rivers, while other groups spawn on shallow shoals or reefs of Lake Erie (Olson and Scidmore 1962;Todd and Haas 1993).…”

“…The largest spawning runs occur in the west, and smaller groups spawn in rivers and reefs of the central and eastern basins (Wolfert 1963;Schneider and Leach 1977). Although tagging studies have revealed relatively little overall migration, some walleye move seasonally from the west to the east (Thomas et al 2005) or west into Lake St. Clair (Ferguson and Derksen 1971;Todd and Haas 1993).…”

Discerning population genetic structure is challenging for highly vagile open water animals, as contemporary gene flow may obscure historic phylogeographic patterns. We examined genetic variation among all 10 major river and reef spawning groups of walleye (Sander vitreus vitreus) in Lake Erie for evidence of isolation by distance, segregation by physiographic partitions, and natal site fidelity using 10 nuclear DNA microsatellite loci. Results revealed that although most spawning groups were distinguishable, relationships did not correspond with physiographic basins or distances among localities. Bayesian analyses showed connectivity among some southern shore spawning groups, which included the largest-sized groups. Significant genetic divergence was discerned among walleye spawning in the river systems of eastern Lake Erie, as well as in two sites in western Lake Erie, along with marked isolation from Lake St. Clair. Population structure of Lake Erie walleye thus appears to reflect the interaction of two different intrinsic factors: isolation due to natal site fidelity that maintains patterns of divergence, and connectivity due to individuals that stray from their natal sites to spawn.Résumé : Il n'est pas facile de déterminer la structure génétique de la population chez les animaux très mobiles dans la masse d'eau, car le flux génique actuel peut obscurcir les patrons phylogéographiques du passé. Par l'analyse de 10 locus microsatellites d'ADN nucléaire, nous avons étudiéla variation génétique dans l'ensemble des dix principaux groupes de dorés jaunes (Sander vitreus vitreus) qui fraient dans les rivières et sur les récifs au lac Érié, à la recherche d'indices d'isolement par la distance, de ségrégation par partitions physiographiques et de fidélité au site de naissance. Nos résultats montrent que, bien qu'on puisse reconnaître la plupart des groupes de fraie, leurs relations ne correspondent pas aux bassins hydrographiques, ni aux distances entre les localités. Des analyses bayésiennes révèlent l'existence de connectivité entre certains groupes de fraie de la rive sud, qui incluent les groupes de plus grande taille. Nos données indiquent aussi une divergence génétique significative chez les dorés qui fraient dans les bassins versants de l'est du lac Érié, de même qu'à deux sites dans l'ouest du lac Érié; elles montrent aussi un isolement vis-à-vis le lac StClair. La structure de population des dorés du lac Érié semble donc refléter l'interaction de deux facteurs intrinsèques distincts, l'isolement due à la fidélité au site de naissance qui maintient les patrons de divergence et la connectivité due aux individus qui s'éloignent de leur site de naissance pour se reproduire.[Traduit par la Rédaction] Strange and Stepien 448

“…For example, juvenile dispersal from spawning sites/natal streams and nursery grounds has been studied for Walleye (Wolfert, 1963) and Lake Sturgeon (Baker, 2006;Lord, 2007;Caroffino et al, 2009), all with the common goal of rehabilitating populations. Two techniques have been used to examine juvenile dispersal: acoustic telemetry (Lord, 2007) and mark-recapture (Wolfert, 1963;Baker, 2006; Caroffino et al, Table 2 Complete list of Laurentian Great Lakes fish movement studies (N = 112), including primary and grey literature, and key characteristics of each study.…”

“…Therefore, understanding the spatial and temporal distribution of stocked fishes can help identify management zones (Schmalz et al, 2002). Stock mixing has been made evident by spawning migrations and inter-lake movements of Yellow Perch in the southern basin of Lake Michigan (Glover et al, 2008) and Walleye from Lake Erie, Lake St. Clair, and southern Lake Huron (Ferguson and Derksen, 1971;Wolfert and Vanmeter, 1978;Haas et al, 1988;Todd and Haas, 1993;Wang et al, 2007). Todd and Haas (1993) combined mark-recapture data with genetic analysis to determine the movement of Walleye stocks between Lakes Erie and St. Clair.…”
