This dataset was first added to MfE Data Service on 28 Sep 2015.
The marine trophic index (MTI) measures the changing abundance and diversity of demersal fish species (living and feeding on or near the seabed) in fishery catches. The Chatham Rise has more than 180 species of fish. It is one of the most productive areas of our exclusive economic zone (EEZ) and an important fishing ground. We calculate the Chatham Rise MTI to assess the change in marine ecosystems resulting from fishing and climate variability.
This dataset relates to the "Marine trophic index: Chatham Rise" measure on the Environmental Indicators, Te taiao Aotearoa website.
