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.
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.
A technique that collects chemical ‘fingerprints’ from the ear bones of fish to help scientists identify which estuaries they originated from could have important implications for the management of New Zealand’s local fisheries, said an article in the latest issue of Fisheries & Aquaculture Update, published by NIWA’s National Centre for Fisheries and Aquaculture.
An agreement in principle has been reached for the sale of the Glenariffe Salmon Hatchery currently owned by NIWA, to Rakaia Salmon Limited. The new company wishes to raise salmon for the market by using the hatchery raceways. Initial concerns by environmental groups over potential capture of young salmon for the farm from the Rakaia River will not be an issue.
The abundance and sizes of fish within the Kapiti Marine Reserve have impressed research divers who have just completed a survey to assess how well the marine environment has recovered since it was protected in 1992.
French researchers are now, or soon to be, closely involved in a range of New Zealand environmental and marine studies taking in such diverse activities as migratory problems of fish including eels, the foraging habits of royal albatross in southern oceans, and the potential tsunami impact of undersea landslides.
New findings by scientists at the National Institute of Water and Atmospheric Research (NIWA) have revealed that the death of kina, starfish, and possibly other fishes, in late January and early February off the Kaikoura coast appears to be linked to toxic algae.
