“…Primers for CIRP were designed based on sequences from the Adriatic sturgeon Acipenser naccarii, which were retrieved from Anaccariibase (Sequence ID: CDNA3-4_11_2010_0_rep_c10569;Vidotto et al, 2013) and aligned against publicly available transcripts using NCBI BLAST(Johnson et al, 2008), sharing highly conserved regions with the sterlet sturgeon, Acipenser ruthensus (Sequence ID: XM_034911883.1; 95.2% identity). Primer sequences for HSP70, HSP90a, HSP90b, RPS6 and RPL7 were designed based on sequences from an annotated lake sturgeon ovary transcriptome produced through pyrosequencing and are the same as used in other lake sturgeon thermal stress experiments(Hale et al, 2009;Yusishen et al, 2020;…”

In Manitoba, Canada, wild lake sturgeon (Acipenser fulvescens) populations exist along a latitudinal gradient and are reared in hatcheries to bolster threatened populations.We reared two populations of lake sturgeon, one from each of the northern and southern ends of Manitoba and examined the effects of typical hatchery temperatures (16 C) as well as 60-day acclimation to elevated rearing temperatures (20 C) on mortality, growth and condition throughout early development. Additionally, we examined the cold shock response, which may be induced during stocking, through the hepatic mRNA expression of genes involved in the response to cold stress and homeoviscous adaptation (HSP70, HSP90a, HSP90b, CIRP and SCD). Sturgeon were sampled after 1 day and 1 week following stocking into temperatures of 8, 6 and 4 C in a controlled laboratory environment. The southern population showed lower condition and higher mortality during early life than the northern population while increased rearing temperature impacted the growth and condition of developing northern sturgeon. During the cold shock, HSP70 and HSP90a mRNA expression increased in all sturgeon treatments as stocking temperature decreased, with higher expression observed in the southern population. Expression of HSP90b, CIRP and SCD increased as stocking temperature decreased in northern sturgeon with early acclimation to 20 C. Correlation analyses indicated the strongest molecular relationships were in the expression of HSP90b, CIRP and SCD, across all treatments, with a correlation between HSP90b and body condition in northern sturgeon with early acclimation to 20 C. Together, these observations highlight the importance of population and rearing environment throughout early development and on later cellular responses induced by cold stocking temperatures.

“…Social buffering appears to be evolutionarily conserved (Oliveira & Faustino, 2017) as it has been observed in primates (Wittig et al ., 2016), rodents (Kiyokawa et al ., 2004), birds (Edgar et al ., 2015), fish (Culbert et al ., 2019; Faustino et al ., 2017; Yusishen et al ., 2020) and invertebrates (Tian et al ., 2017). This phenomenon has been identified in a variety of contexts where the duration of the stressor varied from acute to chronic, social partners were present prior, during (coined exposure-type social buffering) or after the stressor (Hennessy et al ., 2009) and response variables studied were physiological, neural and/or behavioural (Kiyokawa & Hennessy, 2018).…”

“…For example, social signals disrupted the adaptive thermal response of wild, tropical mangrove rivulus ( Kryptolebias marmoratus ) causing these amphibious fish to emerge from water, a marker of their pejus temperature, at higher temperatures than their isolated counterparts (Currie and Tattersall 2018). In gregarious juvenile lake sturgeon ( Acipenser fulvescens ), the presence of conspecifics during acute thermal exposure caused a decrease in both endocrine and cellular stress responses (Yusishen et al ., 2020). The presence of conspecifics has also been shown to modify the preferred and threshold temperatures of the black-axil chromis ( Chromis atripectoralis ) (Nay et al ., 2021).…”

Understanding factors affecting ectothermic fishes' capacity to cope with warming temperature is critical given predicted climate change scenarios. We know that a fish's social environment introduces plasticity in how it responds to high temperature. However, the magnitude of this plasticity and the mechanisms underlying socially-modulated thermal responses are unknown. Using the amphibious, selfing hermaphroditic mangrove rivulus fish (Kryptolebias marmoratus) as a model, we tested three hypotheses: 1) social stimulation affects physiological and behavioural thermal responses of isogenic lineages of fish, 2) social experience and acute social stimulation result in distinct physiological and behavioural responses, and 3) a desensitization of thermal receptors is responsible for socially-modulated thermal responses. To test the first two hypotheses, we measured the temperature at which fish emerged (i.e., pejus temperature) with acute warming with socially naive, isolated fish and socially experienced fish. Our results did not support our first hypothesis as fish socially-stimulated by mirrors during warming (i.e., acute social stimulation) emerged at similar temperatures as isolated fish. However, in support of our second hypothesis, prior social experience resulted in fish emerging at a higher temperature than socially naive fish suggesting an increase in pejus temperature with social experience. We measured whole-body cortisol concentrations of socially naive and socially experienced fish and determined that socially experienced fish had significantly higher cortisol concentrations than socially naive fish. To test our third hypothesis, we exposed socially experienced and naive fish to capsaicin, an agonist of TRPV1 thermal receptors. Socially experienced fish emerged at significantly higher capsaicin concentrations than socially naive fish suggesting a desensitization of their TRPV1 thermal receptors. Collectively, our data indicate that past and present social experiences impact the behavioural response of fish to high temperature. We also provide novel data suggesting that social experience affects the capacity of fish to perceive warm temperature.

“…Juvenile lake sturgeon ( Acipenser fulvescens ) also form loose aggregations, in this case with no evidence of agonistic interactions or social hierarchy formation [ 24 ]. Here again, a comparison of cortisol levels following a stressor consisting of a rapid increase in water temperature supported the occurrence of social buffering, with the rise in cortisol being higher and the recovery to baseline levels slower in single fish than in fish exposed to the stressor in groups [ 25 ]. A species with a more elaborate social structure is the daffodil cichlid ( Neolamprologus pulcher ), a cooperative breeder that lives in relatively stable, size-structured social groups consisting of a dominant breeding pair with (smaller) subordinate helpers [ 26 , 27 ].…”

Social buffering of stress refers to the effect of a social partner in reducing the cortisol or corticosterone response to a stressor. It has been well studied in mammals, particularly those that form pair bonds. Recent studies on fishes suggest that social buffering of stress also occurs in solitary species, gregarious species that form loose aggregations and species with well-defined social structures and bonds. The diversity of social contexts in which stress buffering has been observed in fishes holds promise to shed light on the evolution of this phenomenon among vertebrates. Equally, the relative simplicity of the fish brain is advantageous for identifying the neural mechanisms responsible for social buffering. In particular, fishes have a relatively small and simple forebrain but the brain regions that are key to social buffering, including the social behaviour network, the amygdala and the hypothalamic–pituitary–adrenal/interrenal axis, are functionally conserved across vertebrates. Thus, we suggest that insight into the mechanistic and evolutionary underpinnings of stress buffering in vertebrates can be gained from the study of social buffering of stress in fishes.
