AEBAR informs our decision-making
The 'Aquatic environment and biodiversity annual review' (AEBAR) represents the best scientific information on:
- the effects of fishing on the environment
- marine biodiversity
- aquatic environments.
The information in the review helps us when we make decisions around managing New Zealand's fisheries.
