Freshwater Fishes of Northern Vietnam, 2001

This report is a product of one of the projects in the World Bank's Global Overlays Program primarily financed by the Danish government, though in this case funds from the Swiss government were used to support Dr. Maurice Kottelat's contribution. This particular Overlay project concerned freshwater biodiversity in the context of the Vietnamese National Hydropower Study. It was coordinated by the National Environmental Agency on behalf of the Ministry of Science,echnology and Environment, with technical assistance provided by the World Wide Fund for Nature's office in Hanoi. The objective of the project was to enable water resource planning, particularly with regard to hydropower, to proceed in full consideration of freshwater biodiversity functions and their broad economic values.

Maurice Kottelat has used photographs taken during the curtailed field work together with his unparalleled knowledge of the fish of the region to write a critical analysis of the fish fauna of northern Vietnam. Despite data limitations, this report will be essential reference for those undertaking the biodiversity work as part of Environmental assessments (EAs) for any project affecting water in the area.

This is the first time such a report has been published by the World Bank, but we do so in recognition of the foundational role of taxonomy in sustainable development, of the importance of freshwater biodiversity in the lives of the riparian people of Vietnam (many of them among the poorest of the citizens), and of the need to understand the biological resources for rational planning. We will ensure that, at least in work connected to projects financed by the World Bank, full account is taken of this report, and we look forward to being able one day to producing a user-friendly field guide to these animals as the World Bank has supported elsewhere in the region.

Abstract

268 native species are recorded from the freshwaters of Vietnam (from the Ca River basin northwards) and immediately adjacent waters in China and Laos. The systematic status and nomenclature of all species have been reevaluated. Compared to the last synthesis of the fishes known from the same area, 20 (10 %) of the 203 formerly recognised species are invalid, 85 (42 %) additional species are recognised, and the names of 150 (74 %) of the then-known species are shown to be incorrect (either because of misidentifications, or for various nomenclatural reasons). The fish fauna of the Chinese Provinces of Yunnan, Guangxi, Guangdong, and Hainan has been compared with the Vietnamese fish fauna where relevant in an attempt to make the nomenclatures used in the two countries compatible and in agreement with the International Code of Zoological Nomenclature. Some of the systematic findings and nomenclatural changes are summarised in Tables 1 and 2.

Below you can find the report broken down into 5 files, 3 annexes, and 12 figures.
