“…Individual fish were introduced into a 60 L tank for 1 h of habituation. The values of the CT max and the lethal thermal maxima (LT max ) were considered the temperatures at which the fish showed a loss of body equilibrium and cessation of gill movement, respectively (Peng et al 2014). The oxygen content was measured by an oxygen probe (HQ30, Hach Company, Loveland, CO, USA).…”

“…The temperature at the moment that the fish showed the ''jumping'' behavior for the first time was considered the upper incipient avoidance temperature (AT max ). The values of the CT max and the lethal thermal maxima (LT max ) were considered the temperatures at which the fish showed a loss of body equilibrium and cessation of gill movement, respectively (Peng et al 2014).…”

“…Even if the temperature does not approach the lethal limit, individuals may experience sublethal thermal stress that results in decreased growth and reproduction, thus leading to eventual population failures (Bear et al 2007;Underwood et al 2012;Whitney et al 2016). Laboratory studies have shown that the critical thermal limits of a fish is dependent on the acclimation temperature, and they indicate that a high physiological plasticity in critical thermal limits may greatly facilitate the ability of a fish species to adapt to a new environment (Underwood et al 2012;Peng et al 2014;Chen et al 2015). Laboratory studies have shown that the critical thermal limits of a fish is dependent on the acclimation temperature, and they indicate that a high physiological plasticity in critical thermal limits may greatly facilitate the ability of a fish species to adapt to a new environment (Underwood et al 2012;Peng et al 2014;Chen et al 2015).…”

“…Therefore, knowledge of thermal acclimation and critical thermal limits is important in understanding how a species may respond biologically to different thermal regimes (Du¨lger et al 2012;Whitney et al 2016). Laboratory studies have shown that the critical thermal limits of a fish is dependent on the acclimation temperature, and they indicate that a high physiological plasticity in critical thermal limits may greatly facilitate the ability of a fish species to adapt to a new environment (Underwood et al 2012;Peng et al 2014;Chen et al 2015). To explore the temperature-induced plasticity of the phenotypic characteristics of B. lenok tsinlingensis, an investigation of the critical thermal limits of the fish and a comparison of its thermal acclimation capacity with other Salmonid fishes is required.…”

Brachymystax lenok tsinlingensis is an endangered teleost fish species that occurs in the Qinling Mountain region of China. It also happens to represent the southernmost distribution of an endemic Salmonid fish worldwide. Recently, the habitat of this species shifted towards a higher altitude presumably because of climate change, indicating that this species might be suffering from thermal stress. However, information on the thermal physiology of this species is extremely limited. Accordingly, we investigated the effects of acclimation temperature (6, 12, and 18 °C) on ecologically relevant end points such as critical thermal limits, swimming performance and metabolic rate. Our results showed that elevated acclimation temperatures resulted in increased thermal tolerance and decreased swimming efficiency. High temperature (i.e., 18 °C) did not have a marked effect on the critical swimming speed and the maximum metabolic rate but caused an increase in the energetic cost of transport compared with the results at 12 °C. Interestingly, we found that both the acclimation response ratio and the critical thermal maxima of B. lenok tsinlingensis were higher than that of many other Salmonidae fishes, suggesting that this species responds plastically to temperature changes and has a high thermal tolerance. These characteristics are hypothesized to be related to the southernmost distribution of this species.

“…However, few studies have attempted to evaluate biological aspects of fish such as metabolic parameters, like health or welfare when exposed to short‐term temperature variations. Generally, studies on temperature perform the acclimation procedure at a gradual temperature (on average 1°C/day) and evaluate fish status after a long period of exposure to constant temperature (between 15 and 60 days) or do a quick acclimatization (1°C every 1 or 2 hr) and evaluate the fish status in periods between 12 and 24 hr after acclimatization (Dalvi et al, ; Kır, Sunar, & Altındağ, ; Lushchak & Bagnyukova, ; Peng, Cao, & Fu, ). Many studies showed that temperature influences animal physiological parameters such as metabolic rate, specific dynamic action, heart and ventilatory rates and growth (Dalvi et al, ; Frisk, Skov, & Steffensen, ; Frisk, Steffensen, & Skov, ; Jobling, ; Portner & Knust, ).…”

In this study, the influence of temperature variation on the blood and oxidative stress parameters of pacu Piaractus mesopotamicus juveniles was evaluated. Fish were subjected to gradual changes of temperature, over 5 days, by 24°C until reaching to experimental temperatures 18, 21, 24 (control), 27 and 30°C. There were significant differences (p < .05) in glucose and lactate of blood in both the haematological relationships and oxidative stress parameters. Glucose levels increased at 30°C and decreased at 21°C. Lactate levels were highest at 18°C. While the haematocrit was higher at all altered temperatures, haemoglobin levels decreased at 21°C and increased at 30°C, causing alterations in haematimetric indices. In the liver, glutathione‐S‐transferase (GST) activity was reduced at 18°C while antioxidant capacity against peroxyl radicals (ACAP) was highest at 30°C. Thiobarbituric acid reactive substances (TBARS) increased at 18, 21 and 27°C. In the muscle, ACAP decreased at 27 and 30°C and TBARS increased at 30°C. The results indicate that the species shows sensitivity to temperature variations. Accordingly, we conclude that with short‐term temperature variations >3°C, it is possible to induce higher alterations in the observed parameters in pacu juveniles.

Combined blue light and daily thermocycles enhance zebrafish growth and development

In the wild, the light/temperature environment cyclically oscillates insofar as the temperature rises after dawn and drops after dusk. In the underwater photo‐environment, light is filtered through the water column so that blue photons reach greater depths. This paper investigates the combined effects of both factors with two temperature regimes (constant temperature = 26°C, CTE vs. daily thermocycle = 28°C day:24°C night, TC) and three light wavelengths (white‐W, blue‐B, red‐R) on Danio rerio embryos and larvae from fertilization to 30 days post‐fertilization (dpf). It studied hatching rate, larval survival, growth, and food intake (gut content). It analyzed the expression of the genes involved in stress (crh), somatic growth (gh, ifg1a, igf2a), and food intake control (npy, agrp, ghrelin, orexin, mch1, mch2, grp, cck8) at 10 and 30 dpf. The results revealed that the lowest hatching rate was in R regardless of the temperature regime. The highest growth rate was for the larvae reared with B + TC, which was consistent with the highest expression values of the growth factors. The highest feeding and expression levels of the genes involved in food intake were for the larvae in B (regardless of the temperature regime) and W + TC. Conversely, the R + CTE combination obtained the worst growth and feeding results. These findings indicate that the best larval performance can be achieved with combinations of blue wavelengths and cyclic temperature regimes that come closer to those in the natural environment. These results should be considered when optimizing rearing protocols to improve the growth and welfare of the fish larvae.
