“…In zebrafish, changes in muscle growth trajectories (hyperplasia vs. hypertrophy) induced by manipulation of embryonic incubation temperature were associated with differential expression of miRNAs, with increased Myogenin expression in the higher temperatures that improved growth performance [ 110 ]. Similar findings are also reported in Senegalese sole, in which thermal plasticity of muscle growth was correlated with increased Myogenin expression and regulation of miRNAs with putative roles in muscle development and nutrient metabolism, such as miR-181-5p/3p and miR-206-3p [ 111 , 125 ]. These studies point towards miRNA-related mechanisms that regulate muscle plasticity during temperature manipulation and fluctuation; this information can contribute to the optimization of husbandry strategies to enhance muscle growth or improve fish health and performance.…”

Growth rates in fish are largely dependent on genetic and environmental factors, of which the latter can be highly variable throughout development. For this reason, muscle growth in fish is particularly dynamic as muscle structure and function can be altered by environmental conditions, a concept referred to as muscle plasticity. Myogenic regulatory factors (MRFs) like Myogenin, MyoD, and Pax7 control the myogenic mechanisms regulating quiescent muscle cell maintenance, proliferation, and differentiation, critical processes central for muscle plasticity. This review focuses on recent advancements in molecular mechanisms involving microRNAs (miRNAs) and DNA methylation that regulate the expression and activity of MRFs in fish. Findings provide overwhelming support that these mechanisms are significant regulators of muscle plasticity, particularly in response to environmental factors like temperature and nutritional challenges. Genetic variation in DNA methylation and miRNA expression also correlate with variation in body weight and growth, suggesting that genetic markers related to these mechanisms may be useful for genomic selection strategies. Collectively, this knowledge improves the understanding of mechanisms regulating muscle plasticity and can contribute to the development of husbandry and breeding strategies that improve growth performance and the ability of the fish to respond to environmental challenges.

“…Warm temperatures in early life also cause epigenetic changes (e.g. sex determination; Piferrer, Ribas, & Diaz, 2012), and these epigenetic effects could range from short term (Campos, Valente, Conceicao, Engrola, & Fernandes, 2014) to transgenerational (Burton & Metcalfe, 2014). Of course, the beneficial effects of increased variability are entwined with population size, because small populations cannot afford to lose a large fraction of their population (e.g.…”

Developmental temperature affects phenotypic means and variability: A meta‐analysis of fish data

Fishes are sensitive to their thermal environment and face an uncertain future in a warming world. Theoretically, populations in novel environments might express greater levels of phenotypic variability to increase the chance of surviving—and eventually thriving—in the new conditions. Most research on the effect of the early thermal environment in fish species focuses on average phenotypic effects rather than phenotypic variability, but to understand how fishes will respond to rising temperatures we need to consider both the average response of the population, as well as the breadth of individual responses. Here we present the first meta‐analysis on the effects of developmental temperature in fishes. Using data from 43 species and over 6,000 individual fish, we show that a change in developmental temperature induces a significant change in phenotypic means and variability, but differently depending on whether the temperature is increased or decreased. Decreases in temperature (cool environments) showed a significant decrease in phenotypic means and no change in phenotypic variability. Increases in temperature (warm environments) showed a non‐significant increase in phenotypic means and a marginally significant increase in phenotypic variability. Larger increases in temperature saw greater increases in phenotypic variability, but no increase in the mean phenotypic response. Together, our results suggest that fishes exhibit both directed and stochastic developmental plasticity in response to warming temperatures, which could facilitate or accelerate adaptation to a changing environment.

“…The evolutionary consequences of phenotypic plasticity have long been debated (Crispo 2007). The extent to which stochastic plasticity will help fish populations adapt to a Piferrer et al 2012), and these epigenetic effects could range from short-term (Campos et al 2014) to transgenerational (Burton and Metcalfe 2014). Of course, the beneficial effects of increased variability are entwined with population size, because small populations cannot afford to lose a large fraction of their population (e.g., Devils Hole pupfish Jones et al 2016).…”

Decreases in temperature (cool environments) showed a significant decrease in phenotypic means and no change in phenotypic variability. Increases in temperature (warm environments) showed a non-significant increase in phenotypic means, and a significant increase in phenotypic variability. Larger increases in temperature saw grater increases in phenotypic variability, but no increase in the mean phenotypic response. Together, our results suggest that fishes exhibit both directed and stochastic developmental plasticity in response to warming temperatures, which could facilitate or accelerate adaptation to a changing environment.
