Freshwater fish are an important component of freshwater ecosystems and a valued resource for Māori and recreational fishers. The community of fish species found at a site can be affected by changes in catchment land cover and land use, in-stream habitat, fish passages (routes for moving up and down waterways), pests, and contaminants. The fish index of biotic integrity (IBI) is a measure of the condition of fish communities at sites across the country.
This dataset relates to the "Freshwater fish communities" measure on the Environmental Indicators, Te taiao Aotearoa website.
