“…Because the resistance capacity and time are variable, the use of a certain fixed time limit can lead to under-or overestimation of the true lethal values. In some cases UILT has been determined by extrapolating from resistance results (Edsall & Rottiers, 1976;Kilgour et al, 1985). This extrapolation has been shown to lead to minor differences in UUILT estimation in the present study, but the effect of acclimation and the UILT values were more influenced by the estimation method.…”

“…The UILT increase seems to be higher when species have a higher UUILT level than Arctic charr. For instance underyearling roach Rutilus rutilus L., goldfish Carassius auratus L., and lake whitefish Coregonus clupeaformis (Mitchill) have higher capacity adaptation of UILT with acclimation than Arctic charr (Fry et al, 1942;Cocking 1959;Edsall & Rottiers, 1976). Fry (1971) considered 5 C as a normal level of UILT increase across the temperature gradient.…”

“…Arctic charr has a lower UUILT than lake whitefish but it can resist acute thermal stress longer than lake whitefish. The longest resistance time of Arctic charr was about 2 days, but the lake whitefish reached its upper tolerance limits within 4 h (Edsall & Rottiers, 1976). On the contrary, the resistance time of brown trout is longer than Arctic charr (Elliott, 1981).…”

Underyearling Arctic charr were acclimated to six temperatures between 6 and 21·5 C and thermal tolerance and resistance were tested after an acclimation period of at least 2 weeks. Resistance times were influenced by acclimation temperature and the highest upper incipient lethal temperature was 23-24 C. An upper limit for cultivation of Lake Inari charr is suggested to be 21 C which is the intercept of the function which represents the upper limit of the thermal tolerance zone. 1997 The Fisheries Society of the British Isles

“…Survival was highest at 10.1 and 15.0ЊC (98%) and lowest at 24.1ЊC (81%), which is near the ultimate upper lethal temperature for lake whitefish (26.7ЊC; Edsall and Rottiers 1976). Reduced survival of fish in growth studies at temperatures approaching the upper lethal range is to be expected and has been reported for lake herring C. artedi by McCormick et al (1971) and for bloater C. hoyi by Edsall and Frank (1997).…”

The lake whitefish Coregonus clupeaformis supports major commercial fisheries in Lakes Superior, Huron, and Michigan, where it is managed on a sustainedyield basis; it also supports a recreational hook-and-line fishery in some Great Lakes embayments and nearshore areas. To better understand habitat use by juvenile lake whitefish in the Great Lakes, we acclimated groups of test fish in the laboratory to 5, 10, 15, 18, 21, and 24ЊC and fed them to excess twice daily for 55 d. The test fish increased in length and weight at all of the test temperatures and at the end of the study were heaviest and longest at 18.1ЊC. A curve fitted to the specific growth rate data indicated that the optimum temperature for growth was 18.5ЊC and, thus, that the fundamental thermal niche for juvenile lake whitefish is 15.5-19.5ЊC. Our results support the limited, published information on thermal ecology of wild, free-ranging juvenile lake whitefish in the Great Lakes.

“…Hysteresis values were determined experimentally for each operating mode independently to achieve the most stable water temperatures over time. A maximum temperature of 23°C and a minimum temperature of 7°C prevented exposure to extreme temperatures, which could cause stress or mortality (Edsall and Rottiers, 1976).…”

Thermal preferenda are largely defined by optimal growth temperature for a species and describe the range of temperatures an organism will occupy when given a choice. Assays for thermal preferenda require at least 24 hours, which includes a long acclimation to the tank, limits throughput and thus impacts replication in the study. Three different behavioral assay experimental designs were tested to determine the effect of tank acclimation and trial length (12:12, 0:12, 2:2; hours of tank acclimation: behavioral trial) on the temperature preference of juvenile lake whitefish, using a shuttle box system. Average temperature preferences for the 12:12, 0:12, and 2:2 experimental designs were 16.10 ± 1.07 °C, 16.02 ± 1.56 °C, 16.12 ± 1.59°C respectively, with no significant differences between the experimental designs (p= 0.9337). Ultimately, length of acclimation time and trial length had no significant impact, suggesting that all designs were equally useful for studies of temperature preference.

Temperature Tolerance of Young-of-the-Year Lake Whitefish, Coregonus clupeaformis

Abstract: The ultimate upper lethal temperature of young-of-the-year lake whitefish, Coregonus clupeaformis, was 26.65 C; this value is closely similar to that reported for yearling bloaters, Coregonus hoyi (26.75 C) and young-of-the-year lake herring, Coregonus artedii (26.0 C).
