Somoza Reviews in Aquaculture ABSTRACT Pejerrey is a native fish of the Pampas with relevance in aquaculture and sport fisheries. This review integrates current knowledge on the biology, culture, and physiological adaptations of this species, emphasizing its potential for sustainable aquaculture. From a biological perspective, pejerrey exhibits a unique combination of genotypic and temperature‐dependent sex determination, making it a prime model for studying sex determination in vertebrates. From an aquaculture standpoint, many of the potential limitations of pejerrey farming have been addressed by focused research, such as the low batch fecundity, poor synchronization of maturation, and limited sperm availability are now almost completely mitigated by advances in photothermal and hormonal manipulation of maturation and broodstock husbandry. Osmoregulatory studies confirmed that pejerrey is a euryhaline species, thriving in brackish water, which enhances survival and stress tolerance across all life stages, resolving early misconceptions of pejerrey as a strictly freshwater fish. With survival under control, the low growth rate is now the next research challenge, although it is compensated for by the quality and high market value of the fish. Triploidy induction, interspecific hybridization with the Patagonian pejerrey, and thermal treatments for sex control offer promising avenues for growth improvement through reproductive suppression or monosex culture. The sequencing of its genome paves the way for genetic improvement via genomic selection and gene editing. Ongoing nutritional studies are key to optimizing diets, enhancing growth rates, and improving reproductive success. Further investigations on these and other areas should help realize the aquaculture potential of this economically significant species. 10.1111/raq.70121 http://onlinelibrary.wiley.com/termsAndConditions#vor
