"Climate change the most serious risk to aquaculture: study

VIET NAM
Thursday, February 24, 2011, 23:40 (GMT + 9)

A study conducted on the analysis of stakeholders’ and shrimp farmers’ perceptions in Vietnam’s Ca Mau and Bac Lieu provinces determined that they find climate changes the most serious risk.

Small scale farmers and other stakeholders involved in shrimp aquaculture have been suffering the effects of climate changes via frequent extreme weather events.

The present study run by the Network of Aquaculture Centres in Asia-Pacific (NACA) showed that shrimp farmers perceived too much rain, high temperature, canal/river/sea level rise, irregular weather and storms as their most serious concerns regarding monetary losses.

The study also ranked the risks of the different climate changes in Ca Mau and Bac Lieu provinces, prioritising the gravity of each of the climate changes that the farmers identified. At the top came high temperature and irregular weather (involving factors such as temperature and rainfall), followed by excessive rain, sea level rise and storms.

Over the years, shrimp farmers have begun to adapt towards more flexible and versatile methods by modifying their management practises to suit the changing climate, including water management, modernising the pond dyke and using lime, probiotics and other chemicals."
