“…In contrast, Jansen et al. () found that similar levels of temperature drops used in this study did not significantly affect hatching success in yellow perch eggs. Their results, coupled with results presented herein, suggest that yellow perch have potentially evolved to withstand substantial changes in water temperatures during their early life history.…”

“…While temperature declines may not have significantly increased mortality, it was interesting to note the qualitative differences in behaviour that existed among treatments. The fact that eggs continued to hatch in both the control and −4 treatments suggests that drops in temperature of less than 4°C likely will not negatively impact yellow perch hatch success (Jansen et al., ). Additionally, while the simulated cold‐front was occurring, fry remained active and were found throughout the water column in both the control and −4 treatments.…”

Summary Acute reductions in water temperature (i.e. cold fronts) may influence larval fish survival directly via limits on physiological tolerance or indirectly by acting as a sublethal stressor. The primary objective was to quantify survivorship of yellow perch yolk‐sac fry exposed to two different temperature declines (4 and 8°C) and compare survivorship to that of perch fry under ambient temperatures representative of natural conditions. Behaviour of yolk‐sac fry following temperature declines was also qualitatively assessed. Mean survival in the control, −4, and −8 treatment tanks was 90, 91 and 97%, respectively, and no significant differences in percent survival were observed between the control and the −4 treatment (ts = −0.10; df = 7; P = 0.93), the control and −8 treatment (ts = −1.85; df = 7; P = 0.11) or the −4 and −8 treatments (ts = −1.33; df = 7; P = 0.22). Observations of yellow perch eggs and fry behaviour following temperature declines differed among treatments. Any remaining eggs in the control treatment and −4 treatments continued to hatch during the experiment, and fry were documented swimming throughout the water column in all tanks. However, in the −8 treatment, any eggs that had not hatched remained inactive and all fry within all −8 treatment tanks ceased swimming activity and settled to the bottom of the tanks once the temperature reached 3.9°C. Fry remained at the bottom of the tanks for the entire 48 h simulated cold‐front. Fry resumed swimming activity once water temperatures began to increase (by approximately 6°C). Results indicated that drops in temperature (i.e. cold fronts) similar to or greater than those found in small impoundments did not cause direct mortality of yellow perch during the yolk‐sac fry (post‐hatch larvae) stage. Although an acute drop in temperature may not induce sudden high mortality, it may be a sub‐lethal stressor, leading to increased starvation or predation risk.

Comparisons of a species' genetic diversity and divergence patterns across large connected populations vs. isolated relict areas provide important data for understanding potential response to global warming, habitat alterations and other perturbations. Aquatic taxa offer ideal case studies for interpreting these patterns, because their dispersal and gene flow often are constrained through narrow connectivity channels that have changed over geological time and/or from contemporary anthropogenic perturbations. Our research objective is to better understand the interplay between historic influences and modern-day factors (fishery exploitation, stocking supplementation and habitat loss) in shaping population genetic patterns of the yellow perch Perca flavescens (Percidae: Teleostei) across its native North American range. We employ a modified landscape genetics approach, analysing sequences from the entire mitochondrial DNA control region and 15 nuclear DNA microsatellite loci of 664 spawning adults from 24 populations. Results support that perch from primary glacial refugium areas (Missourian, Mississippian and Atlantic) founded contemporary northern populations. Genetic diversity today is highest in southern (never glaciated) populations and also is appreciable in northern areas that were founded from multiple refugia. Divergence is greater among isolated populations, both north and south; the southern Gulf Coast relict populations are the most divergent, reflecting their long history of isolation. Understanding the influence of past and current waterway connections on the genetic structure of yellow perch populations may help us to assess the roles of ongoing climate change and habitat disruptions towards conserving aquatic biodiversity.

“…Subdaily fluctuations can occur naturally in nearshore areas in large lakes (Wells & Parker 2010;Troy et al 2012;Cossu & Wells 2013) or via anthropogenic activities including near industrial thermal discharges (Cooke & Schreer 2003;Coulter et al 2014). However, yellow perch (Perca flavescens), European perch (Perca fluviatilis) and walleye (Sander vitreus) appear resilient to sudden temperature declines, as egg survival, hatching success, developmental rates and larval survival were not affected by either acute (≤12 h) drops of up to 8°C (Schneider et al 2002;Jansen et al 2009;VanDeHey et al 2013) or hourly temperature fluctuations of 3°C (Paxton & Willoughby 2000). Coulter et al (2015) determined that increasing the magnitude of 12-h thermal cycles from D 4°C to D 8°C reduced growth rates in juvenile fathead minnows (Pimephales promelas) during the first 6 weeks of life, even though the mean and maximum temperatures of the cycles were at or below the species' optimum and upper lethal temperatures, respectively.…”

Fluctuations in water temperature can have important physiological consequences for fishes. Effects of daily thermal cycles are well studied and can be beneficial, increasing prey consumption and growth rates when mean and maximum temperatures of the fluctuations are at or below the species' optimum temperature. While less studied, subdaily temperature fluctuations are also common in many aquatic habitats and can be caused by both natural and anthropogenic processes. We performed laboratory experiments to examine how two fish species (yellow perch, Perca flavescens, and walleye, Sander vitreus) with similar thermal preferences respond to chronic exposure to subdaily temperature variability. We selected temperature treatments that reflected observed thermal variation after examining water temperature data from multiple aquatic systems. We then separately exposed yellow perch and walleye to a stable 23°C treatment and 12-h cycles of 23 AE 2°C or 23 AE 4°C for 45 days. Adult yellow perch exposed to fluctuations of 23 AE 4°C over 12 h expressed higher consumption, growth and food conversion efficiency than fish experiencing stable 23°C. Temperature fluctuations, though, resulted in mortalities and the development of skin ulcers in yellow perch that did not occur under stable temperatures. In contrast, the same 12-h temperature fluctuations did not result in mortalities or stress responses in juvenile walleye. Moreover, unlike yellow perch, growth rates of walleye were lower under 12-h temperature fluctuations compared with the stable 23°C treatment. Our results indicate that species with similar thermal preferences can respond differently to the same subdaily temperature fluctuations.
