This document was prepared in response to requests from governments for advice on the impacts from introduction of economically important alien Penaeid shrimps to Asia. The review was conducted by FAO, Network of Aquaculture Centres in Asia-Pacific (NACA), World Wildlife Fund (WWF), and the
World Bank (WB) Consortium Programme on Shrimp Farming and the Environment (http://www.enaca.org/shrimp/). The review is published as an FAO Regional Office for Asia and the Pacific (FAO/RAP) publication through its generous assistance. This document was made possible by the contributed country reviews of a number of country correspondents several of whom have preferred to remain anonymous due to the often sensitive nature of this subject. Additional valuable comments and suggestions were made by many colleagues.
The authors would therefore like to thank the country correspondents from Viet Nam, Indonesia, India, Sri Lanka, Thailand as well as the following individual experts: Chen Aiping, Fred Yap, Dato Mohamed Shariff M. Shariff, N. Gopinath, Ng Chee Kiat and Ben Ponia. The authors would also like to thank Shunji Sugiyama for his assistance with the statistics presented in this document.
