“…The importance of wind events is generally unexplored for the early life stages of freshwater fishes, but it is well recognized for marine fish larvae. Wind-driven currents serve an important role regulating the survival of marine larvae such as Arctic cisco Coregonus autumnalis along the Beaufort Sea coast, where strong recruitment is linked to years with high winds that transport larvae (Fechhelm and Griffiths 1990). Wind-induced currents also influence other Great Lakes larvae, such as those of cisco Coregonus artedi in Lake Superior, by transporting them from spawning areas (Hoff 2004).…”

Processes regulating the survival of early life stages are difficult to decipher for fishes, especially those occupying multiple spatially segregated habitats in large complex systems. Although the processes occurring during the juvenile period are often thought to regulate recruitment of freshwater fishes, those occurring during prolonged pelagic larval phases may be more important to fishes inhabiting large dynamic systems, as is the case with marine larvae. To assess the importance of biotic and abiotic factors on growth and survival of a freshwater fish with a prolonged larval phase, we collected age‐0 yellow perch Perca flavescens in Lake Michigan across multiple habitats and used otoliths to estimate daily ages, hatching distributions, and growth and mortality rates. Larval yellow perch hatched near shore over a 4‐ to 6‐week period but were quickly transported offshore, where they experienced prolonged pelagic durations. Water temperature and wind events influenced growth rates, whereas water temperature, wind events, prey availability, hatching date, and growth rate affected survival across habitats. Mechanisms regulating growth and survival of yellow perch during prolonged pelagic durations (stage duration, prey, and wind events) are consistent with recruitment mechanisms typically ascribed to marine systems, suggesting that abiotic mechanisms interact with biological factors to govern recruitment of fishes in large freshwater ecosystems.

“…In Alaska, C. autumnalis make long‐distance movements from spawning to rearing locations and smaller scale annual marine migrations between feeding and overwintering habitats. Coregonus autumnalis captured in Alaskan waters are the progeny of fish that spawn in tributaries of the Mackenzie River, Canada (Craig, 1989; Fechhelm & Griffiths, 1990). Spawning and hatching success has not been extensively studied in Canada, but hatching is thought to coincide with spring freshet and river break‐up as it does with other coregonids (Næsje et al , 1986, 1995; Urpanen et al , 2005).…”

Arctic cisco Coregonus autumnalis young-of-year (YOY) growth was used as a proxy to examine the long-term response of a high-latitude fish population to changing climate from 1978 to 2004. YOY growth increased over time (r² = 0·29) and was correlated with monthly averages of the Arctic oscillation index, air temperature, east wind speed, sea-ice concentration and river discharge with and without time lags. Overall, the most prevalent correlates to YOY growth were sea-ice concentration lagged 1 year (significant correlations in 7 months; r² = 0·14-0·31) and Mackenzie River discharge lagged 2 years (significant correlations in 8 months; r² = 0·13-0·50). The results suggest that decreased sea-ice concentrations and increased river discharge fuel primary production and that life cycles of prey species linking increased primary production to fish growth are responsible for the time lag. Oceanographic studies also suggest that sea ice concentration and fluvial inputs from the Mackenzie River are key factors influencing productivity in the Beaufort Sea. Future research should assess the possible mechanism relating sea ice concentration and river discharge to productivity at upper trophic levels.

“…For example, Fechhelm and Griffiths (1990) studied the 600-700 km westward transport of Arctic cisco (Coregonus autumnalis) larvae along the Alaskan and Canadian Beaufort Sea coast. They found that years of moderate to high recruitment were associated with strong easterly winds during summer, and years of poor recruitment occurred when easterly winds were weak.…”

Larval cisco (Coregonus artedi) were sampled from Lake Superior off the western coast of the Keweenaw Peninsula (Michigan, USA) to determine if the Keweenaw Current influences their distribution and growth. Bongo net tows were conducted during April-June 2000 from four transects extending from 0.1 to 17 km offshore. For most sampling dates, cisco tended to be slightly more abundant, larger, and older at inshore locations. Later-hatched larvae appeared at the western-most transects first, during which time earlier-hatched larvae disappeared from the study area. This pattern followed what would be expected if larvae were being transported eastward by the prevailing Keweenaw Current. Estimated growth rates were 84% higher for later-hatched compared with earlier-hatched larvae and 25% lower for offshore larvae from the eastern-most transects compared with elsewhere. Accordingly, surface water temperatures partly explained spatial and temporal variations in growth rate. These results indicate that cisco larvae in Lake Superior may be transported great distances from major spawning sites by longshore currents and that the temperature regime of nursery areas may largely control their growth.Résumé : Nous avons échantillonné des larves de ciscos de lac (Coregonus artedi) du lac Supérieur au large de la côte occidentale de la péninsule de Keweenaw (Michigan, É .-U.) afin de déterminer si le courant de Keweenaw affecte leur répartition et leur croissance. Nous avons effectué des traits de filets bongo en avril-juin 2000 sur quatre transects allant de 0,1 à 17 km de la rive. Pour la plupart des dates d'échantillonnage, les ciscos avaient tendance à être légèrement plus abondants, plus grands et plus vieux dans les sites près de la rive. Les larves à éclosion plus tardive apparaissent d'abord dans le transect situé le plus à l'ouest, au moment où les larves à éclosion plus hâtive ont disparu de la zone d'étude. Ce patron s'accorde avec ce qu'on peut attendre si les larves sont transportées vers l'est par le courant prédominant de Keweenaw. Les taux de croissance estimés chez les larves à éclosion tardive sont 84 % plus élevés que ceux des larves à éclosion hâtive et ils sont de 25 % inférieurs chez les larves du large dans le transect le plus à l'est par comparaison à tous les autres sites. En conséquence, les températures des eaux superficielles expliquent en partie les variations spatiales et temporelles des taux de croissance. Nos résultats indiquent que les larves de ciscos du lac Supérieur peuvent être transportées sur de longues distances à partir des principaux sites de fraye par les courants côtiers et que les régimes thermiques des zones de nourricerie peuvent en grande mesure contrôler leur croissance.[Traduit par la Rédaction]
