摘要：The global importance of mesopelagic fsh is increasingly recognised, but they remain poorly studied . This is particularly true in the Southern Ocean, where mesopelagic fshes are both key predators and prey, but where the remote environment makes sampling challenging . Despite this, multiple national Antarctic research programs have undertaken regional sampling of mesopelagic fsh over several decades . However, data are dispersed, and sampling methodologies often difer precluding comparisons and limiting synthetic analyses . We identifed potential data holders by compiling a metadata catalogue of existing survey data for Southern Ocean mesopelagic fshes . Data holders contributed 17,491 occurrence and 11,190 abundance records from 4780 net hauls from 72 diferent research cruises . Data span across 37 years from 1991 to 2019 and include trait-based information (length, weight, maturity) . The fnal dataset underwent quality control processes and detailed metadata was provided for each sampling event . This dataset can be accessed through Zenodo . Myctobase will enhance research capacity by providing the broadscale baseline data necessary for observing and modelling mesopelagic fshes .
