The skeletal muscle of teleost fish is remarkable in its capacity for indeterminate growth and phenotypic plasticity to function across different environmental conditions. Generation of the sarcomeric proteins that comprise the muscle myofibrils is the single biggest contributor to protein synthesis in fish muscle. In the past decade, numerous studies have shown sarcomeric proteins, especially those of the troponin complex and myosins, exhibit altered expression in exceptionally rapidly growing fish muscle. This includes cases associated with inherent inter-individual variation in growth rates, including hybrid vigour, and induction during rapid compensatory growth. The purpose of this review is to present the evolutionary mechanisms (i.e. whole genome and gene duplication) responsible for the expanded genomic array of sarcomeric proteins found in teleost fish. On this backdrop, the parallels between then changes in sarcomeric gene expression linked with growth and those associated with thermal acclimation (an example of phenotypic plasticity) are discussed. The plasticity associated with optimizing muscle performance during thermal acclimation appears closely coupled with indeterminate growth, and I speculate on some of the endocrine factors (e.g. thyroid hormone signaling) where the two are likely to converge. Together, this review provides a timely synthesis of the determinants of sarcomeric protein expression in fish, and highlights areas ripe for future investigation. This review also emphasizes that, to facilitate comparisons between different species and across various contexts of muscle growth and plasticity, it is imperative that upcoming studies on genes encoding sarcomeric proteins in teleost fish adopt a consistent and evolutionarily-informed universal nomenclature.
