Pest fish throughout New Zealand

Abstract

Kia ora koutou. I have been asked to give a general overview of pest fish in New Zealand. Introduced fish are highly adaptable, frequently invasive and often cause problems. They are difficult to detect and notoriously hard to eradicate. For that reason it is no surprise that a group of goldfish is known as troubling. But it is not all doom and gloom. I will talk about what species are pests, who has a role in managing them, what problems they cause, what has been done about them and what we still need to work on.
