NIWA scientists are asking for help from people who have had a long association with East Northland, Hauraki Gulf or Marlborough Sounds.

NIWA is looking for people who have had a long association with the Hauraki Gulf or Marlborough Sounds to help them with a research project on juvenile fish habitats.

Over the last few days the “dive team” have been recording corals, fishes, urchins and other invertebrates from the shallow waters (0-30m) surrounding Raoul Island to complement the biodiversity records from the deeper ocean collected by the other scientists onboard.

Using a very wide net to complete a 960m deep mesopelagic trawl near the Kermadec Islands has brought up a large number and diverse range of deep water species.

The Quota Management System, which some say saved New Zealand fisheries, is 30 years old today. The system is founded on science that studies fish biology, abundance and distribution, and estimates how many can be caught and still keep the population healthy.

At the edge of the advancing winter sea ice in the Ross Sea, a first-ever winter fisheries survey has uncovered new secrets of the Antarctic toothfish.

Sea ice-based toothfish surveys have been carried out in McMurdo Sound since 2014.

A bibliography of some of the journal papers and CCAMLR Working Group papers published about the toothfish fishery.

The fishery is managed differently depending on the region and specific environmental protection and fishery management objectives in the region.

Find out about the role of toothfish in the ecosystem and the potential effects of fishing.

A survey series in the Southern Ross Sea was started in 2011 to index juvenile abundance.
