Taranaki is de ned by the mountain and a large network of rivers, lakes and streams. There are over 20,000km of waterways, with 530 named rivers and streams, and 19 lakes spanning an area greater than eight hectares. Collectively these awa are the lifeblood of Taranaki, providing freshwater to sustain the environment,
the people and the economy, and are home to many native sh, shell sh and invertebrates.
Many of the freshwater sh species migrate from stream to ocean to spawn. Maintaining and restoring sh passage will increase the resilience and productivity of these treasured species. Left uncontrolled, invasive pest sh, aquatic plants and algae can have a considerable
impact on the biodiversity and community health
of freshwater ecosystems.
