Abstract
Aquaculture - belonging to the Fisheries group - is one of the high-value economic sectors, accounting for a large part in the structure of the agriculture, forestry and fishery industry in Vietnam. However, the sustainability of this industry is facing many challenges due to climate change process; An Giang is a province that has long had a strong position in aquaculture in Vietnam and is not out of that influence. Therefore, there is an urgent need to assess climate change vulnerability of aquaculture in An Giang based on the predicted changes in temperature and rainfall of the region according to the change scenarios. climate. Unlike previous studies conducted mainly on a national scale, this paper is mainly concerned with Pangasius (Pangasius is one of the aquatic species with high commercial value, with significant contribution). including livelihoods of people in An Giang province) - species raised in the main production areas of An Giang and assess their vulnerability for each area, using an index-based method and Intergovernmental Panel on Climate Change Definition of Vulnerability to overcome constraints in developing specific adaptation strategies at regional scale. First, for each exposure, sensitivity and adaptability, specific and appropriate indicators are chosen. These indicators are then estimated and weighted to analyze vulnerability to climate change. The results show that the level of vulnerability due to climate change to the pangasius farming industry in An Giang province is at a moderate level, of which Chau Phu district is highly vulnerable because the district has the main livelihood of Pangasius farming.

Nghiên cứu này tiến hành xây dựng được bộ chỉ thị đánh giá tính dễ bị tổn thương do BĐKH cho cá tra tỉnh An Giang trong bối cảnh BĐKH
Aquaculture that belongs to Fishery is one of the high-value economies accounting for a significant portion in the economic structure of Agriculture- Forestry- Fishery in Viet Nam and An Gianga province that has prevailed in Aquaculture in Viet Nam
Its sustainability has been facing many obstacles derived from climate change; it is essential to evaluate the vulnerability of climate change affecting shark catfish farming in An Giang based on the prediction of temperature and rainfall obtained from sets of conditions of climate change and evaluate their vulnerability for each area by using a numerical method and based on Intergovernmental Panel on Climate Change in vulnerability to overcome the difficulties in development strategies adapt for a certain area
