Fisheries science

IWA aims to provide the key science services required by the national and international fisheries sectors and their industry partners.

Our Vision is sustainable fisheries and stewardship of the marine environment.

Our Mission is to provide impartial scientific advice to inform managers, stakeholders, and Māori partners.

Our Goal is to improve the ability to predict responses of fisheries and ecosystems to management actions and environmental change.

To be successful, we require knowledge and understanding of the biology, distribution, and abundance of exploited and associated species, and of the key processes in the ecosystem, including how fisheries affect the environment, and how the environment affects fisheries.
