Estuary clean up to boost whitebait spawn
Hawke’s Bay Regional Council is working with hapū to improve the biodiversity of the Tukituki River estuary near Haumoana to make it more suitable for whitebait spawning.
Ecological advisor Hans Rook says removing invasive silver poplars and weeds will create more space and better conditions for spawning.
Council staff will reshape one bank to create a shoulder above the high tide level for spawning and trim ngaio trees to give more light at ground level and to promote dense grass growth, which makes the best spawning habitat for the fish.
Mr Rook says Hawke’s Bay has a good track record for managing whitebait habitat, and spawning habitats have been identified, protected and enhanced since the 1980s.
