A giant squid and several glow-in-the-dark sharks were surprise finds for NIWA scientists last month on the Chatham Rise during a voyage to survey hoki, New Zealand’s most valuable commercial fish species.
NIWA is in its third year of a 5-year phased project on the deepwater line fishery in Tonga funded by the NZ Aid Programme’s Partnership for International Development Fund. The aim of the project is to deliver the improved governance, management, and economic and biological sustainability of the fishery focusing on deepwater snapper and bluenose in the Tonga EEZ.
A video about The world's most mysterious fish. NIWA researchers are working with iwi to try to unlock the secrets of New Zealand tuna—freshwater eels. Every year tiny, glass eels wash in on the tide at river mouths along our coast. But where do they come from and how do they get there?
Sustainable fisheries depend on good scientific data about fish stocks. NIWA scientists head out into Cook Strait on Research Vessel Kaharoa to survey the hoki fishery and advise officials on catch rates.
The on-going rise of carbon dioxide (CO2) in the atmosphere is not only changing our climate—it is also changing our oceans. Take a look at the work of the NIWA-led CARIM project into what these changes may mean for the delicate balance of marine life.
Despite many centuries of maritime exploration, only a fraction of our planet's seafloor has been observed. NIWA Deepsea Scientist Di Tracey tells us what it feels like to probe deep beneath the waves to see what's living on the ocean floor.
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.
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.
