Autonomous adaptation to climate change by shrimp and catfish farmers in Vietnam’s Mekong River delta

The Mekong River delta of Vietnam supports a thriving aquaculture industry but is exposed to the impacts of climate change. In particular, sea level rise and attendant increased flooding (both coastal and riverine) and coastal salinity intrusion threaten the long-term viability of this important industry. This working paper summarizes an analysis of the economics of aquaculture adaptation in the delta, focusing on the grow-out of two exported aquaculture species—the freshwater striped catfish and the brackish-water tiger shrimp. The analysis was conducted for four pond-based production systems: catfish in the inland and coastal provinces and improved extensive and semi-intensive/intensive shrimp culture.

Containing the diseases in aquaculture

A brief discussion is presented on epizootics and their containment in the aquaculture industry, in the form of a question-and-answer interview. Particular reference is made to activities carried out by the OIE (Office International des Epizooties), whose main activities include the provision of guidelines and standards for health protection applicable to international trade in live animals and their products. It has devised an early warning system to apprise its member countries of the occurence of disease outbreaks that would have serious repercussions on public health or the economics of animal products.
