Fisheries

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.
