List of fish species identified and cross-referenced by an integrative taxonomy analysis. Specimens were identified to the lowest taxonomic level using morphological features. A sub-sample of small muscle tissue from each individual was taken for DNA extraction and amplification of two mitochondrial genes, cox1 and the non-coding control region (CR).

Special attention was given to larval and juvenile specimens. Samples were collected by fishery observers on board krill fishing vessels for the winter seasons between 2019 and 2024. Extra samples collected before 2019 were obtained from the biological archives at BAS including muscle and fin tissue as well as otolith samples spanning from 1988 through 2022. All samples were measured and photographed prior to be subsampled for DNA. Most samples were blast-freeze and stored at -20 degrees C or fixed in 90% ethanol. Tissue samples were stored in 90-95% ethanol and kept at -20 degrees C. Data resources from this project were used to developed enhanced identification guides for larval and adult fish species caught as bycatch within the Antarctic krill fishery.

This is a Darwin plus initiative awarded to Philip, R. Hollyman under round 10 funding scheme, project reference DPLUS166.
