Fisheries

NIWA research ship Tangaroa has been chartered by the Ministry of Primary Industries to survey the Hoki fishery on the Chatham Rise during January and early February 2018.

“You almost become a fishing psychologist – you can tell by the way people walk up the ramp to get their trailer if they’ve had a good day.”

Rapid warming of the ocean near Tasmania may provide a good indication of how the water around New Zealand will change as the planet warms, say NIWA scientists.

Does climate change affect the position of the Subtropical Front around New Zealand?

Unlike other ecosystem models, machine learning is built solely from the information it is presented.

Ecopath with Ecosim (EwE) is trophodynamic modelling software that uses a mass-balance approach to describe ecosystem based, marine food web interactions.

Spatially explicit disturbance/recovery models are a cellular automaton that uses a mechanistic approach to investigate recovery rates of benthic species following disturbance events.

Resource trade-off models are spatial models that use biological, environmental and socio-economic data to optimise management (protected area designation) across potentially conflicting uses, or across different ecosystem services.

MICE (Models of Intermediate Complexity) is a type of ecosystem model that is question-driven, and contains a limited number of components and ecological processes.

At NIWA, we consider all components of the marine ecosystem important when trying to better understand the role of dynamic, ecosystem processes on the distribution and abundance of marine organisms in New Zealand’s marine environments.

Approximately 500 Aquatic invertebrate taxa are described in this database, made available to assist with the identification of specimens.
