DNA barcoding of shared fish species from the North Atlantic and Australasia: minimal divergence for most taxa, but Zeus faber and Lepidopus caudatus each probably constitute two species (2008, background): “Surveys of several hundred fish species (Ward et al. 2005, 2008, Rock et al. 2008) show that the average degree of intraspecific differentiation for the COI barcode region is around 0.4%, with >90% of cases showing <1% differentiation.”
Using DNA barcodes to connect adults and early life stages of marine fishes from the Yucatan Peninsula, Mexico: potential in fisheries management (2010, background): “For example, Rock et al. (2008) analysed 35 fish species from the Scotia Sea, reporting that COI (cytochrome oxidase subunit I gene) provided effective species-level discrimination that was unaffected by broad geographic sampling.”
DNA barcoding detects market substitution in North American seafood (2008, unknown): “This includes both freshwater (Hubert et al., 2008) and marine fishes (Rock et al., 2008; Spies, Gaichas, Stevenson, Orr, & Canino, 2006; Ward, Holmes, White, & Last, 2008; Ward, Zemlak, Innes, Last, & Hebert, 2005).”
The campaign to DNA barcode all fishes, FISH-BOL. (2009, background): “A study of Scotia Sea fishes revealed that barcoding enabled species discrimination in all cases except for Bathydraco and Artedidraco, where introgressive hybridization or misidentification may be involved (Rock et al., 2008).”
