Mangrove plantation for enhancing food web in water recycling shrimp farms.
MetadataPerlihat publikasi penuh
Environmental deterioration in ponds and costal waters has been a common evidence after each intensive shrimp culture due to the accumulation of organic wastes and occurrence of eutrophication processes. Mangrove is a wetland that potentially supports the natural food web in the estuary and coastal areas. The planting of mangroves in recycling shrimp farms would serve the purpose of developing sustainable shrimp farms by utilizing the enriched organic matters and nutrients thus enhancing the natural food web in the shrimp farms. However, mangrove trees in pond dikes tend to grow small and the roots may not be able to support the tree during pond erosion resulting in the mortality of the mangrove trees. Brackishwater weeds, which cover the soil in the pond dikes, could serve the function of the young mangrove trees.
This activity was implemented from November 2000 to April 2001. As reported during the Mid-Project Workshop in September 2001, the change in the Center’s thrust towards freshwater aquaculture made it not possible to conduct the activity in Chachaengsao beyond 2001. Hence, this activity was no longer reported during the Regional Seminar-Workshop held in Bangkok in June 2003.
