“…Managing to prevent cold‐shock stress is very difficult as causal events tend to be temporally and spatially unpredictable. Currently, there are several mitigation measures that can be taken to reduce the risk of cold‐shock stress and mortality on fishes (Wilde, 1988; Nickel et al , 2004), but until more research can be conducted, management bodies that take a precautionary approach should consider rapid declines in temperature as a threat to fish species. Although a number of guidelines for protecting fish from deleterious temperature regimes have been proposed (Oliver & Fidler, 2001; US EPA, 2003), the majority of these guidelines fail to specifically consider cold shock.…”

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. Rapid temperature decreases may occur from either natural (e.g. thermocline temperature variation, seiches and storm events) or anthropogenic sources (e.g. varied thermal effluents from power generation and production industries). The magnitude, duration and frequency of the temperature change as well as the initial acclimation temperatures of individuals can influence the extent of the consequences of cold shock on fishes. Early research on cold shock focused on documenting mortality events associated with cold shock. However, in recent years, a shift in research has occurred where the focus of cold-shock studies now involves characterizing the sublethal effects of cold shock in terms of the stress response in fishes. This shift has revealed that cold shock can actually be used as a tool for fisheries science (e.g. to induce polyploidy). The cold-shock stress response offers opportunities to develop many exciting research questions, yet to date, cold-shock research has been largely unfocused. Few studies attempt to link laboratory physiology experiments with ecologically relevant field data on behaviour, growth, bioenergetics and fitness. Additional research will allow for the development of more focused and robust management policies and conservation initiatives. This review synthesizes the sublethal physiological and behavioural consequences of cold-shock stress on fishes, identifies natural and anthropogenic sources of cold shock, discusses the benefits of cold shock to fisheries science and describes mitigation and management efforts. Existing knowledge gaps and opportunities for future cold-shock research are presented.

“…HSPs have been found to repair and prevent damage from cellular stress associated with protein denaturation at high and low temperatures (Nakano and Iwama, 2002;Werner et al, 2005). However, HSPs expression is fluctuating at both stresses according to fish species (Werner et al, 2005;Wilde, 1988). Glutathione S-transferases (GST), one of the oxidative stress-related genes, its expression associated with different kinds of stressors (Almroth et al, 2015;Garcia et al, 2015).…”

Abstract. Owing to its cold-blooded nature, water temperature is a driving force in fish life. The aim of this study is to explore the effect of the thermal stress of ambient temperature during summer and winter in Nile tilapia (Oreochromis niloticus) on heat shock proteins (HSP70, HSP27), oxidative stress genes (MT and GST) and some immune response genes (IL-1, IL-8, and TLR7). As well as to compare the DNA fragmentation at both variant temperatures using RAPD-PCR and micronucleus assay. The fish were collected twice, once at the end of December (winter sample, temperature 14˚C), and the other at August (summer sample, temperature 36˚C). qRT-PCR analysis of mRNA expression for the studied genes were done. HSP70 expression increased equally in gills and liver at both summer and winter, suggesting its advantageous role in fish survival in the labile environment. Its expression exceeds HSP27 level, whose expression increased in summer. GST expression increased in summer in liver than gills and expressed equally at both organs in winter. No differences were observed in MT and immune response related gene expression in both seasons. The very close pattern of RAPD-DNA fragmentation and micronuclei were recorded at both thermal stresses. We conclude that, thermal stress of cold and hot extremes of ambient temperature in Nile tilapia have a nearby role in expression of HSP70, MT, liver GST and immune response related genes. As well as the incidence of micronucleus and DNA fragmentation.

“…Studies have repeatedly documented the attraction of fish to heated discharges during cold months (Benda and Proffitt 1973). In addition, numerous laboratory studies have been conducted to determine the effects of heat and cold shock on fish (e.g., Reutter and Herdendorf 1976;Wilde 1988). However, Sawyko and Smythe (1983) suggested that the application of laboratory results should not be generalized and related to field locations for which relevant parameters may be unknown.…”

Winter Residency of Smallmouth Bass in a Thermal Discharge Canal: Implications for Tempering Pump Operation

The behavior of smallmouth bass Micropterus dolomieu was studied in the Nanticoke Thermal Generating Station discharge canal on Lake Erie during the winter to examine the effects of thermal tempering pump operation. A series of seven fixed underwater antennas continuously monitored movements of 20 radiotagged fish from January 7 until March 15, 1998. Fish were released at the head of the discharge canal, upstream from the eight tempering pumps where they were captured. Most fish spent the entire study within 25 m of the release site. Small-scale movements occurred when fish moved back and forth from the most upstream tempering pump (which was not operational during the study) to an adjacent eddy. Five fish moved greater distances throughout the length of the discharge canal, with most of their time spent in areas that provided velocity refuges and cover (e.g., large rip-rap and oil-boom structures); their movements appeared to be independent of environmental conditions. The benefits of the thermal tempering pumps for smallmouth bass in the discharge canal in winter appear to be minimal because the majority of their time was spent upstream of pump influence. The design and operation of power plant cooling systems should consider the tradeoffs between the actual mitigative effects of tempering pump operation and the increased fish impingement and entrainment associated with such operating conditions.
