Taxonomy and population structure of commercially important Indo-Pacific squids of the Uroteuthis (Photololigo) chinensis species complex
A project undertaken at the NSW Department of Primary Industries and supervised by Dr Karina Hall
In eastern Australian waters, coastal squid are taken primarily as byproduct in trawl fisheries, with the bulk of the catch comprising broad and slender squids. These two morphologically similar species are currently classified within the Indo-West Pacific mitre squid U. (P.) chinensis complex, which has a wide species distribution extending from eastern Australia to southwestern Japan. However, preliminary genetic analyses of specimens from northern Australia in the early 1990s, suggest that broad and slender squids may be separate undescribed species with more limited species distributions.
This collaboration between the NSW Department of Primary Industries, Queensland Department of Agriculture and Fisheries and Queensland Museum will combine fisheries and taxonomic expertise with modern molecular methods to investigate the taxonomy and population structure of the U. (P.) chinensis species complex in eastern Australian waters. This information will be used to inform more accurate risk and stock assessments for these commercially important species.
