Samenvatting (in Engels)
In response to increasing concerns about sustainable production, a growing number of European customers expect seafood products to be certified, for example by the Aquaculture Stewardship Council (ASC) certification. Water purification technologies such as Recirculating Aquaculture Systems (RAS) could be a potential solution to reduce waste discharge and to improve water quality in fish ponds as a response to environmental regulations. This thesis was to perform an economic analysis of technological innovations such as RAS to improve the sustainability of pangasius production in Vietnam. Overall, the probability of RAS being a profitable investment is 99% for both medium and large farms. Crucial factors leading to improved economic performance of RAS compared to traditional system are the improved pangasius yields and pangasius prices. Main constraints for adoption of RAS are the lack of trust in receiving a price premium, lack of access to finance, and uncertainty about the performance of RAS.
