Donating to freshwater ecology and fisheries research programmes

Do you want cutting edge science to inform the protection of our nation’s rivers, lakes and streams? 

New Zealand’s freshwaters and fisheries are degrading in response to various environmental pressures, foremost being intensive agricultural land use. People’s enjoyment of freshwater is increasingly curtailed due to poor water quality and diminished flows, and largely unregulated recreational usage.

Cawthron Foundation has established a funding opportunity for donors interested in supporting long-term research that will help stem the consequences of unsustainable exploitation of our freshwaters and fisheries.


Cawthron scientists have the expertise to provide world-class freshwater science, including fisheries, and have pre-eminent track records in these areas. Good science is key to proper implementation of environmental legislation for truly sustainable freshwater and fisheries management.

Our history makes us confident that philanthropic funding can make a positive contribution to providing solutions to the challenges facing New Zealand’s freshwaters and freshwater fisheries. By supporting research in this area donors would be helping answer some pressing questions such as:

Freshwater ecology

  • What are the most effective measures of freshwater quality?
  • How can we rehabilitate our rivers, lakes and streams?
  • How can we work together with local councils, iwi, farmers and community members to rehabilitate our freshwater ways? 

Freshwater fisheries

  • What are fish water quality and quantity needs?
  • How do fish respond to environmental degradation?
  • How might we rehabilitate freshwater ecosystems to reverse the decline of our fisheries? 

The video below outlines some recent research work completed by our freshwater scientists into the importance river flow for fish growth and abundance.
