Abstract The Jonah’s icefish Neopagetopsis ionah is endemic to the frigid, oxygen-rich waters of the Southern Ocean. This species has evolved remarkable genetic and physiological adaptations, notably the loss of functional hemoglobin, making it an exemplary vertebrate model for studying evolutionary loss is gain and adaptation to extreme environments. In this study, we present a chromosome-level genome assembly of N. ionah (1.27 Gb) integrating Illumina, PacBio HiFi, and Hi-C sequencing data.

1 Introduction In modern large-scale aquaculture, proactive disease management has become an integral part of husbandry protocols. Although conventional antibiotic treatments were initially effective, their long-term use is increasingly undermined by the emergence of antibiotic resistance—a trend that conflicts with contemporary demands for food safety and public health (Acosta et al. 2019; Verma et al. 2021).
