Invasive species

A NIWA-led programme to develop effective, and culturally-attuned strategies for managing the freshwater gold clam.

Introduced pests and diseases can harm the health of Aotearoa New Zealand's marine ecosystems, our seafood industry, and the social and cultural benefits that we derive from the sea.

Could bubbles and strobe lights stop pest fish swimming where they’re not wanted?

Investigating the effectiveness of an acoustic bubble-screen in minimising the movement of pest fish

Reducing the risk of new freshwater invasive species, minimising the impacts of these species, and developing methods for reducing or eradicating those populations.

Aotearoa-New Zealand’s marine area covers 167,650 square kilometres presenting a staggering distribution of climates, from subtropical to subantarctic waters, to understand and manage.

NIWA has world-class expertise in marine macroalgae and extensive research on various aspects of seaweed ecology, growth and taxonomy.

NIWA is part of a multi-agency biosecurity response to an invasive seaweed discovered at Aotea Great Barrier Island and subsequently at Ahuahu Great Mercury Island.
