Genetic identification of fish caught as by-catch in the Antarctic krill fishery and comparison with observer records
48.1, 48.2 and 48.3) were identified by DNA barcoding and results compared with morphological ... barcoding markers allowed these specimens to be assigned to species level. The diversity of fish identified ... by observers (5 families; 8 species) was considerably lower than with DNA barcoding (7 families; 20 ... species). The impact of potential taxonomic misidentifications on fish bycatch datasets needs to be ...
