“…The zebrafish (Danio rerio), for example, a thermophilic fish with a short life cycle, has an intrinsic plasticity with greater tolerance on the part of adults to high temperatures when the juveniles also have been exposed to high temperatures (Schaefer and Ryan, 2006). Another reference for muskellunge (Esox masquinongy), however, shows no difference in thermal tolerance among 2-year-old individuals from different populations (Wagner et al, 2007). It is therefore a property difficult to generalize; we can note, however, that the truly reliable temperatures in situ are systematically around 1°C to 4°C lower than the lethal temperatures (Magnuson et al, 1979;Eaton et al, 1995); for this reason, we advise retaining as the benchmark the thermal tolerance maximum (7th column in the table in Appendix).…”

The effects of industrial cooling water on fish communities were widely debated at the end of the seventies, when large thermal power plants were being developed. This led to numerous research programs on thermal tolerance in fish. The recent warming climatic period and especially the 2003 heat wave have brought thermal biology back to center stage. The work presented here has consisted in analyzing historical and contemporary literature to update basic knowledge on thermal tolerances of 19 riverine fish species. These data were then validated and completed by European fish specialists. We finally proposed a synthesis, based on more than 300 references, which details thermal tolerances for the entire life cycle: reproduction, embryonic, larval, juvenile and adult life stages. This updated material is of great importance to an understanding of the trends observed in fish communities or for forecasting future behavior in climate change scenarios. RÉSUMÉSynthèse des tolérances thermiques des espèces de poissons communes des rivières et fleuves de plaine de l'ouest européen L'effet de l'élévation de température des cours d'eau a été largement débattu à la fin des années 70 qui ont connu le développement des centrales thermiques de grande puissance. Ces études ont généré alors de nombreux programmes de recherche sur la tolérance thermique des poissons, dont les résultats sont parfois oubliés ou difficiles à rassembler. Le réchauffement climatique actuel et en particulier l'épisode caniculaire de 2003 a mis de nouveau ce thème sur le devant de la scène. Le travail de synthèse présenté a consisté à analyser des données historiques et contemporaines de la littérature, afin de mettre à jour les connaissances de base sur les tolérances thermiques de 19 espèces de poissons d'eau douce. Cette synthèse a ensuite été validée et complétée par des spécialistes européens. Elle s'est appuyée sur plus de 300 références qui détaillent les tolérances thermiques de chacun des stades du cycle de vie des espèces étudiées : reproduction et stades embryonnaire, larvaire, juvénile et adulte. Cette mise à jour est essentielle pour comprendre les tendances d'évolution déjà constatées des communautés de poissons et prévoir les futures évolutions en fonction de différents scénarios de changement climatique.

“…For example, organisms at the low latitude/altitude end of their range may occupy habitat that is warmer relative to the thermal optimum than those at the high latitude/altitude end of their range. Such low latitude/altitude organisms may be impacted by warming differently than organisms elsewhere in their range, although this depends on whether thermal optima are locally adapted, a point that is still debated in the literature (Wagner and Wahl, 2007). Optimum temperatures are also affected by other factors such as organism age, food intake, and time of year (Nichelmann, 1983; Cossins and Bowler, 1987).…”

Hester, Erich T. and Martin W. Doyle, 2011. Human Impacts to River Temperature and Their Effects on Biological Processes: A Quantitative Synthesis. Journal of the American Water Resources Association (JAWRA) 47(3):571‐587. DOI: 10.1111/j.1752‐1688.2011.00525.x Abstract: Land‐use change and water resources management increasingly impact stream and river temperatures and therefore aquatic organisms. Efforts at thermal mitigation are expected to grow in future decades. Yet the biological consequences of both human thermal impacts and proposed mitigation options are poorly quantified. This study provides such context for river thermal management in two ways. First, we summarize the full spectrum of human thermal impacts to help thermal managers consider the relative magnitudes of all impacts and mitigation options. Second, we synthesize biological sensitivity to river temperature shifts using thermal performance curves, which relate organism‐level biological processes to temperature. This approach supplements the popular use of thermal thresholds by directly estimating the impact of temperature shifts on the rates of key biological processes (e.g., growth). Our results quantify a diverse array of human thermal impacts, revealing that human actions tend to increase more than decrease river temperatures. Our results also provide a practical framework in which to quantify the sensitivity of river organisms to such impacts and related mitigation options. Finally, among the data and studies we synthesized, river organisms appear to be more sensitive to temperature above than below their thermal maxima, and fish are more sensitive to temperature change than invertebrates.

“…After establishing the general location of the fish, approximate final positions were determined based on the signal strength (Wagner and Wahl 2007). The specific UTM coordinates for transmitter locations were recorded using a geographic positioning system (GPS) receiver, with detailed notes made on fish locations in reference to easily distinguishable landmarks (Curry et al 2007).…”

“…In addition, as muskellunge inhabit temperate water bodies, seasons likely impact habitat selection and general movement patterns; a phenomenon previously found in northern pike (Esox lucius), a congeneric species (Knight et al 2008;Kobler et al 2008a,b). Seasonal habitat preference and movement patterns are directly influenced by the available habitat and the type of water body (Casselman 2007;Miller and Menzel 1986a;Wagner and Wahl 2007). Muskellunge typically increase activity once ice-out occurs and is highest during the spring and fall transitional periods when fish are moving to and from spawning and wintering habitats (Dombeck 1979;Younk et al 1996).…”

-The Rideau Canal in Canada was constructed in the 1800s to enable strategic military and commercial transport in eastern Ontario between Lake Ontario and the Ottawa River. Today, the Rideau Canal is managed by Parks Canada and remains an engineered ecosystem, particularly in the urban Ottawa reach (7 km long) where it is largely channelized and is partially drained during the winter to protect canal infrastructure (i.e., locks) and provide recreational opportunities (i.e., skating). Interestingly, the Ottawa reach of the Rideau Canal supports one of the few wild urban muskellunge (Esox masquinongy) fisheries in North America supported by natural reproduction. However, little is known about the spatial ecology, residency patterns or survival of this apex freshwater predator in urban environments or canal systems. Radio-telemetry was used to study adult (N = 10; total size range of 64 to 122 cm) muskellunge in the Ottawa reach of the Rideau Canal over a multiple year period. The seasonal movements and home range of muskellunge were greatest during spring corresponding with the period when water levels in the canal were raised and muskellunge were presumably seeking out suitable spawning habitats following ice-off. During the summer fish ranged throughout the entire 7 km urban reach of the canal and by early fall muskellunge moved to the deeper parts of the reach and became largely restricted to an embayment known as Dow's Lake prior to the lowering of the canal where they stayed for the entire winter. The same pattern of seasonal movements persisted across several years. None of the tagged muskellunge were stranded from the fall canal drainage. One fish emigrated from the urban reach of the canal during the study period, moving upstream through a lock to an exurban reach. In addition, a single tagged fish died from a winterkill event. Environmental influences such as seasonality and water depth (associated with canal operations) are believed to be the primary mechanisms contributing to habitat selection and movement patterns of muskellunge in this reach of the Rideau Canal. Data on the spatial ecology of muskellunge in the urban reaches of the Rideau Canal will inform management of this unique population of fish to ensure that the historic and ecological values are balanced to preserve this iconic Canadian natural heritage site and its biota.
