Growing high-value species is all about getting the conditions right. NIWA is measuring the performance of kingfish in different environments, in readiness for new marine space becoming available.
We’re comparing growth rates of thousands of electronically-tagged kingfish at Bream Bay (Northland) and Mahanga Bay (Wellington), where temperatures are about 4–5o C cooler.

A team of NIWA fisheries scientists has just completed the fourth of five resource assessment surveys for the Oman Ministry of Fisheries Wealth, working in the Arabian Sea off the coast of Oman.

The recent New Zealand International Polar Year – Census of Antarctic Marine Life (NZ IPY-CAML) survey to the Ross Sea will produce the first-ever abundance estimates for Antarctic silverfish (Pleuragramma antarcticum) using acoustics.
Silverfish are a small pelagic (free-swimming) fish that act as a key link between plankton and the top predators such as seals,penguins, and toothfish, in the shelf waters of the Ross Sea.
