20 years of Chatham Rise fish surveys

 

NIWA has run the Ministry of Fisheries-funded Chatham Rise survey using R.V.Tangaroa every year since 1992. The main aim of the surveys is to estimate the abundance of hoki and other commercially important species (such as hake and ling), but during the 20 consecutive surveys NIWA scientists have also been able to study other aspects of deepwater biodiversity on the Chatham Rise, including fish distribution, abundance, and ecology. 

Rig shark

 

Rig shark is an important inshore commercial fish species in New Zealand, and we need to understand more about their habitats, movements, nursery grounds and vulnerability to human impacts to ensure they are managed sustainably and their productivity is enhanced.

The Ross Sea Trophic Model

Understanding the feeding relationships between different species in the Ross Sea, and how they are affected by commercial fishing, is essential for the establishment of a sustainable fishery in the region.

Marine food webs

We need information on the food web structures of our marine ecosystems in order to manage the effects on the ecosystem of fishing, aquaculture and mining, as well as understanding the potential impacts of climate variability and change on our oceans.
