A three-year trial to convert waste from dairy farms into feed for fish has begun in New Zealand. The project aims to use dairy shed effluent to farm algae and has been constructed as a complete system. The algae are cultured in purpose-built ponds and then transported to separate ponds to feed zooplankton: an excellent source of nutrition for fish. The zooplankton ponds are linked to the Aongatete River by a fish-friendly passage.
This project is funded by local and national government bodies and has been designed by the National Institute of Water and Atmospheric Research together with Raglan EELS.
