AEBAR informs our decision-making
The Aquatic environment and biodiversity annual review (AEBAR) 2021 represents the best scientific information as at June 2021 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.
You can download the full report, or individual chapters.
