Regional examples and resources for Fish Passage
This page lists different regional examples and resources for Fish Passage.
Evidence from Our freshwater 2023 shows the strain on the health of our rivers, lakes and other water bodies around Aotearoa New Zealand.
The report shows that 76% of native freshwater fish species were threatened with extinction or at risk of becoming threatened in 2017. Ten of 18 taonga freshwater fish and invertebrate species were, too.
Fish can be affected by structures like dams, weirs and flood pumps – which hamper their ability to migrate and breed.
Data suggests 48% of the country’s river network is at least partially inaccessible to migratory fish - and the figure may be higher.
Find out more about the state of our freshwater and impacts on native and taonga species on our website.
