This collaborative NZaid project worked with coastal Fijian villagers at Votua on the Coral Coast of Viti Levu to develop pragmatic water supply and waste treatment solutions to protect public health and reduce contamination of coastal waters.

NIWA's seafood sector work comprises our fish, fisheries and aquaculture research and consultancy.

Technical information about our datasets and methodology along with related resources.

Wastewater treatment is the separation and extraction of solid waste from liquid waste, and the removal of nutrients and pathogens.

Identifying biological factors that may be limiting fish numbers requires sampling to ensure that key invertebrate prey species are not scarce and that pest fish, especially predators, are not abundant.

What are the potential sources of chemical contamination from aquaculture activities?

Defining drought and identifying its causes and impacts on humans.

Southland is both the most southerly and most westerly part of New Zealand and generally is the first to be influenced by weather systems moving onto the country from the west or south.

This lesson will explore the use of Māori environmental indicators [tohu] to anticipate local weather and climate conditions.
