“…thermal bars (Botte and Kay, 2000;Coats et al, 2006). Organisms may experience a change in water temperature over a long period, with the potential to adapt or acclimate (Wilson et al, 2000), or they may experience a rapid temperature change, with the risk for temperature-induced shock (Donaldson et al, 2008). …”

SUMMARYBody temperatures and thus physiological rates of poikilothermic organisms are determined by environmental temperature. The power an organism has available for swimming is largely dependent on physiological rates and thus body temperature. However, retarding forces such as drag are contingent on the temperature-dependent physical properties of water and on an organism's size. Consequently, the swimming ability of poikilotherms is highly temperature dependent. The importance of the temperaturedependent physical properties of water (e.g. viscosity) in determining swimming speed is poorly understood. Here we propose a semi-mechanistic model to describe how biological rates, size and the physics of the environment contribute to the temperature dependency of microbial swimming speed. Data on the swimming speed and size of a predatory protist and its protist prey were collected and used to test our model. Data were collected by manipulating both the temperature and the viscosity (independently of temperature) of the organism's environment. Protists were either cultured in their test environment (for several generations) or rapidly exposed to their test environment to assess their ability to adapt or acclimate to treatments. Both biological rates and the physics of the environment were predicted to and observed to contribute to the swimming speed of protists. Body size was not temperature dependent, and protists expressed some ability to acclimate to changes in either temperature or viscosity. Overall, using our parameter estimates and novel model, we are able to suggest that 30 to 40% (depending on species) of the response in swimming speed associated with a reduction in temperature from 20 to 5°C is due to viscosity. Because encounter rates between protist predators and their prey are determined by swimming speed, temperature-and viscosity-dependent swimming speeds are likely to result in temperature-and viscosity-dependent trophic interactions.

“…Rapid decreases in water temperature may result in a number of physiological, behavioural, and fitness consequences for fishes termed "cold-shock". Cold-shock stress occurs when a fish has been acclimated to a specific water temperature or range of temperatures and is subsequently exposed to a rapid decrease in temperature, resulting in a cascade of physiological and behavioural responses and, in some cases, death (Donaldson et al, 2008).…”

“…However, generally the values of blood ions and osmolality were lower at 12°C, which means lower temperature slightly affect the blood properties of grey mullets. McCormick et al (2000) stated that water temperature can affect the activity of gill Na Acclimation to low temperature or cold shock lead to failure in osmotic regulation such that fish in saltwater gained plasma electrolytes while freshwateracclimated fish losed ions (Donaldson et al, 2008).…”

Grey mullet (Mugil cephalus) can adapt to saline and freshwater. Although belonged to euryhaline species, but information regarding their stress response on low temperature. Environmental disturbance such as low water temperature may effect their physiological condition. These information can be useful for aquaculture development of this species in freshwater. Therefore, the purpose of study was to investigate the effects of low water temperature on the stress response of grey mullets Mugil cephalus acclimated in freshwater. The blood samples of experimental fish (TL: 28.2±1.1 cm, BW: 198.6±25.9 g) were collected during winter season when the water temperature of controlled rearing system was stable at 25°C and uncontrolled rearing system slowly dropped until 12°C. Their stress response on both rearing systems was observed. The results showed that low temperature affected to lower the behavior activity and increase the stress response of grey mullets. The breath frequency of grey mullet regarding their opercular movement at 12°C was 74-97 breath/min., while at 25°C it was 95-114 breath/min. Hematocrit (Ht) and hemoglobin (Hb) were shown higher values of 43.5% and 9.5 g/dL, respectively at 25°C than 12°C (28.0% and 7.1 g/dL, respectively). The tendencies of cortisol and glucose level increased with the lowering temperature, showing higher value of 264.8 ng/mL and 35.5 mg/dL in 12°C than 5.5 ng/mL and 32.7 mg/dL in 25°C. The chemical properties of blood in grey mullets showed same tendency comparing between 12°C and 25°C, there was no significant different between each temperature, except for chloride (P<0.05). Chloride value was higher at 25°C, while other blood components such as osmolality, sodium, potassium, and magnesium were showing no significant differences. However, the results showed lower values at 12°C in every blood components, except for chloride. In conclusion, lowering water temperature to 12°C had impact as stressor to the behavior and stress response of grey mullets acclimated in freshwater.

“…These HSPs act as chaperone proteins that repair proteins damaged by external environmental stressors and play a role in maintaining the normal functions of the cells (Welch 1991;Donaldson et al 2008). In particular, HSP70 is highly expressed in various tissues and is known to play an important role in cellular metabolism (Nakano and Iwama 2002).…”

: In this study, we investigated the effects of light spectra on physiology stress and DNA damage in juvenile rock bream (Oplegnathus fasciatus) using light-emitting diodes (LEDs; green, 520 nm; red, 630 nm) at two intensities (0.25 and 0.5 W/m 2 ) with application of thermal stress (25 and 30 o C). We measured the mRNA expression of heat shock protein 70 (HSP70) and the levels of plasma cortisol, glucose, aspartate aminotransferase (AspAT), and alanine aminotransferase (AlaAT). Additionally, DNA damage was measured using comet assays. Our findings showed that HSP70 mRNA expression and plasma cortisol, glucose, AspAT, and AlaAT levels were significantly higher after exposure to high temperatures and were significantly lower after exposure to green LED light. Thus, although high water temperatures induced stress in juvenile rock bream, green LED light inhibited stress. In particular, green LED light reduced stress and DNA damage to a greater degree than other light sources.
