World Aquaculture Magazine - June 2020

WWW.WA S.ORG • WORLD AQUACULTURE • JUNE 2020 25 There are currently several large national and international projects on domestication and selective breeding of different species (e.g. striped catfish, air-breathing fish, giant freshwater prawn) for better adaptation, salinity tolerance and growth in brackish water, however, more work is urgently needed. As mentioned above, there has been good innovation in aquaculture technology in the Mekong Delta but the current farming systems need to be continuously improved at a large scale to mitigate the impacts of climate change and saltwater intrusion. Advanced systems such as modern pond culture, modern cage culture and indoor recirculating aquaculture systems should be considered and promoted appropriately. In the Mekong Delta, there are networks for environmental monitoring and disease pathogen surveillance. It is necessary to promote this work further, to serve, interact and consult more effectively with farmers, applying the advances of the fourth industrial revolution. Aquaculture extension activities are very dynamic in the region, training farmers about climate change and saltwater intrusion as well as solutions to mitigate impacts and adapt to climate change and saltwater intrusion are urgently needed. Considering that climate and saltwater intrusion are critical issues, the government has been effectively serving the aquaculture industry in the Mekong Delta particularly and the country generally with legal and institutional management as well as other solutions.
