Protecting our native fish species

New Zealand has around 40 native fish and 70% of them are threatened or at risk.

Many of our iconic species, such as whitebait and eels, need to move between the sea and rivers to complete their lifecycles. If these movements are delayed or blocked, these fish may be unable to reach habitats for completing their lifecycle, and they may be lost from a stream completely.

HBRC is trying to find all fish barriers around Hawke's Bay so we can prioritise and fix those ones that would have the greatest benefit to the regional biodiversity and abundance of our fish communities. Please help us locate any structures in our waterways that you think fish may struggle to swim over/around. Use the link below to send us details and provide us with photos and we will take it from there.

If you are on a river or stream and see any:

• Raised (‘perched’) culverts or drains
• Waterfalls with a drop greater than 10cm
• Rapids with steep gradients over 20 degrees
• Fast flowing water with no obvious resting places for fish
• Grates, gates or mesh that might block fish

Please report a fish barrier to us here

Adult inanga (the main whitebait species) really struggle to get over barriers. ​​ Mussel spat rope provides a cheap fix for many barriers. Here you can see banded kokopu whitebait climbing the spat rope. Photo credit: Bruno David   Example of a fast water culvert barrier with vertical fall.
