Address by the Chairman of the Workshop We of the Asian Fisheries Society are grateful to the Australian International Development Assistance Bureau for making this workshop possible. I consider it a deep honour to be invited to Chair this workshop and wish to express my gratitude to my fellow Councillors for bestowing this privilege and take this opportunity to welcome all the participants to this workshop. In keeping with one of the main objectives of the Asian Fisheries Society, to address key issues pertaining to fisheries in the region, the Council at its Second Meeting in 1984 unanimously decided that the Introduction of Aquatic Organisms into the region needed careful consideration. We were aware that this issue was also being addressed by some international organizations amongst others, and the American Fisheries Society. In spite of these considerations the Society felt a need to consider this issue; complex as it is from an Asian context where the the socio-economic factors cannot be ignored and or separated from the fisheries issues in general. Initially, four Objectives for the Workshop were identified: address the issue of aquatic introductions in the region, evaluate the pros and cons of introductions hitherto made in the region, develop guidelines/a code of ethics for future introductions, and issue a policy statement on future introductions. It is unlikely that we would be able to fulfill our objectives within the next three days. I consider this workshop as the first step in the direction of achieving our objectives. In order to do so we will have to address our minds to a few key points: Do we have sufficient information/knowledge of the situation in each of the countries in the region - if so how do we proceed to collect this information, especially that in the 'grey literature' Do we need to develop protocols for consideration by Governments in the region, and if so what criteria should we use: should they take into account the socioeconomic factors, etc. Are there recent examples from the region or elsewhere on proposed introductions that impel us to think afresh? Undoubtedly all of us would agree that we should not adopt, clause to clause, what has been recommended as suitable for Northern America, Europe and or for that matter mainland Australia. This is not because we want to be different but such a course of action would be self defeating. If we were to do the former there would not have been a need to come to this lovely city, Darwin. Equally, we have a lot to gain from their experiences. ix
Conditions in Europe and North America are not comparable to that of ours ir the region. Here, I do not mean in a climatological sense but in the context of the numbe: of species involved, complexity of the habitats, heterogeneity of the flora and fauna, anl the gross beneficial effects of some introductions that have contributed to the animal protein supply. Some of the socio-economic benefits of introductions are not totally quantifiable but they certainly cannot and should not be ignored. Ladies and Gentlemen with these few remarks, which I hope would help us to focus at some of our deliberations, I wish to commence the proceedings. We should all bear in mind that the deliberations of the next three days will direct the Society's future course of actioa in dealing with this very complex issue. Finally, it is my duty to express our gratitude and appreciation to the local organizers Mr. Darryl Grey and his team, for their excellent arrangements. Thank you. Sena S. De Silva x
