Aquatic Biodiversity & Biosecurity Update

This electronic newsletter was produced by the National Centre for Aquatic Biodiversity and Biosecurity. Articles range from the discovery of a giant octopus to distribution of native fish in New Zealand waterways, and from detection of introduced marine species to biosecurity threats to geothermal streams.


Welcome to Aquatic Biodiversity & Biosecurity Update, the e-newsletter of NIWA's National Centre for Aquatic Biodiversity & Biosecurity. Here, we will bring you news of research, courses, and events NIWA is engaged in to advance the understanding and protection of New Zealand's aquatic biodiversity.
