Australia's marine fishes DNA barcode reference library for integrated taxonomy, metabarcoding & eDNA research.

Over 15 000 species of fishes are found globally in the marine environment and DNA barcodes are used extensively to describe, catalogue, understand and manage this diversity. The dataset outlined here represents a DNA barcode reference library of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) from 9767 voucher specimens (representing at least 2220 species and 288 families) of marine fishes. This publicly available dataset in the Barcode of Life Data System (BOLD) represents 17 years (2005-2022) of barcoding of marine fishes identified from Australian territorial waters. Tissues targeted for sequencing with their matching physical specimens (and extracted DNA), obtained via a multi-agency sampling effort, are mostly maintained and curated by the CSIRO Australian National Fish Collection (ANFC) in Hobart, Australia. Species-level integrated taxonomy (assigned after combined morphological and genetic assessment) has been determined for 91% of the dataset. The library represents the most complete COI barcode reference dataset for marine fishes from Australian waters and is currently utilised for integrated taxonomy, (meta)barcoding and eDNA studies.
