Fisheries

Balancing the sustainability of our fisheries stocks and the impacts of fishing on the environment with the economic opportunities they offer is an ongoing challenge.

Commercial catch sampling

The Otolith is the earbone of the fish and like the rings on a tree it can tell us about the story of the fish's life. NIWA has looked at 27000 otoliths in the last year each one contributing to the story of key species in the fishery.  Together this information informs managers about the growth, recruitment, and selectivity of the fishing gear which is crucial for managers to make sustainability decisions. Good management of a fishery requires good data. This video is a look at what goes into collecting that data. 

Surveying scallops populations with artificial intelligence

Together with the University of Canterbury and Fisheries NZ, NIWA has been working to develop a catch-free, non-invasive method of surveying scallop populations. Find out how...

To get the most benefit from a fish stock in the long term, we need to maximise our yield without damaging the fish population we rely on.

Epic spiny red rock lobster

Sam Fraser-Baxter heads to the Wairarapa for one of New Zealand’s longest-running marine surveys – counting baby lobster.

Robust science is critical to the sustainable use of New Zealand's significant marine and freshwater fisheries. New Zealand's Exclusive Economic Zone (EEZ) is the fifth-largest in the world and home to over 16,000 marine species.

130 of those species are fished commercially, earning the country $1.5 billion in export receipts each year. Balancing the sustainability of our fisheries stocks and the impacts of fishing on the environment with the economic opportunities they offer is an ongoing challenge.
