New Zealand Invasive Fish Management Handbook

Editors: Kevin J. Collier and Natasha P.J. Grainger

This handbook provides information about managing and monitoring invasive fish in New Zealand. It covers:

- The impacts of key invasive fish
- The statutory responsibilities of different agencies
- Approaches to control, eradication and surveillance, and
- Ways to assess invasion risk including an analysis of human perceptions and awareness.


Invasive fish pose a major threat to the health and integrity of freshwater ecosystems globally. By definition, they reproduce and disperse rapidly, are capable of tolerating a wide range of environmental conditions, and quickly reach very high numbers often dominating the biomass of fish present. Through their feeding and other activities they can adversely affect water quality and native species, contributing to the degraded and depauperate state of freshwater ecosystems. New Zealand has not escaped this plight, with several introduced fish now widespread around the country, particularly in northern New Zealand. Managing and monitoring invasive freshwater fish is a challenge that requires involvement of multiple agencies and use of multiple tools for control, eradication and surveillance. This handbook represents a joint initiative between DOC and The University of Waikato’s Lake Ecosystem Restoration New Zealand (LERNZ) research programme, part of which focussed on invasive fish management. It provides a key reference for those involved in invasive fish management, as well as a resource for policy makers, students and interested public.

New Zealand's Rivers: An Environmental History

Author: Catherine Knight   Publisher:Canterbury University Press

‘New Zealand’s Rivers: An environmental history’explores the relationship between New Zealanders and our rivers, explaining how we have arrived at a crisis point, where fresh water has become our most contested resource and many rivers are too polluted to swim in. Environmental historian Catherine Knight reveals that the tension between exploitation and enjoyment of rivers is not new. Rivers were treasured by Māori as food baskets and revered as the dwelling places of supernatural creatures. But following European settlement, they became drains for mining, industrial waste and sewage, and were harnessed to generate power and to irrigate farmland. Over time, the utilitarian view of rivers has been increasingly questioned by those who value rivers for recreation as well as for ecological, spiritual and cultural reasons. Today, the sustainable use of rivers is the subject of intense debate. Thoroughly researched and richly illustrated, ‘New Zealand’s Rivers’is an accessible and compelling read for all New Zealanders, including anglers, kayakers, farmers, environmental practitioners, policy-makers, students and anyone with an interest in our environment and history.

The Waters of the Waikato - Ecology of New Zealands Longest River.

Editors: Kevin Collier, David Hamilton, Bill Vant and Clive Howard-Williams

The Waters of the Waikato: Ecology of New Zealand’s Longest River is a case study of an iconic New Zealand river. It is of great cultural and spiritual significance, has considerable economic and recreational value, and provides a place to live for a wide variety of plants and animals. This book tells a story
of this river’s physical and chemical environment and the life it supports, from the turbulent blue waters at the outlet of New Zealand’s largest lake down to the tidal waters of the river delta. It is a contemporary synthesis of current scientific knowledge of the river, and will provide a reference for
river managers, policy makers, students and the interested public.

Price: $25 incl GST - Numbers are limited.

Advances in New Zealand Freshwater Science

Editors: Phillip G Jellyman, Tim JA Davie, Charles P Pearson, Jon S Harding

In 2004 the New Zealand Freshwater Science and New Zealand Hydrological Societies published a joint book Freshwaters of New Zealand. This book was the first comprehensive summary of hydrological and ecological research in New Zealand fresh waters and included contributions from a wide range of scientists and managers. Advances in New Zealand Freshwater Science summarizes new hydrological and ecological research in streams, rivers, wetlands, ponds, lakes and groundwater over the last 12 years. This book comprises 34 chapters with over 100 contributing authors. Some research themes have been the focus of much new research since 2004, while freshwater management in New Zealand has undergone some profound changes. In particular there have been major advances in catchment and environmental modelling, invasive species (such as didymo), and new pond and wetland research with greater emphasis on restoration and rehabilitation. This book also recognises the greater engagement with Māori in freshwater management and the changing policies invoked by the National Policy Statement for Freshwater Management. Advances in New Zealand Freshwater Science will be of interest to scientists, practitioners, managers, students and lay people and is particularly timely given the increasing public interest in the state of New Zealand’s fresh waters.

Price: $90 (plus $10 for postage and handling within NZ).  Please enquire for overseas postage prices.
