Fisheries tools and resources

NIWA provides software and systems to analyse fisheries.

Population modelling software

CASAL2 is an advanced software package developed by NIWA for modelling the population dynamics of marine species.

Echo sounder technology

CREST is a highly adaptable approach to fisheries and other acoustic data acquisition, using the concept of a "software echo sounder".

Trawl fisheries bycatch

Accurate reporting on the amount of fish and invertebrates that are caught and discarded by New Zealand’s commercial fishing industry is vital to effective management of these fisheries.

Quantum mapping

 NIWA Quantum Map is a free, open source, desktop mapping tool based on the popular Quantum GIS application.

Spatial population modelling

The Spatial Population Model (SPM) can model populations over one or two areas, as well as populations in many hundreds of areas.

DTIS - Deep Towed Imaging System

DTIS is a camera system designed and built by NIWA staff, which is used to take pictures and video of deep sea biodiversity and seafloor habitats at depths of up to 6km.
