Abstract
Alternative rice-prawn farming system is important and has become a typical system in the Mekong Delta. To evaluate the development in terms of technical and socio-economic aspects of the systems teo questionnaire sueveys were conducted in 2006 on a total of 59 farmers in Can The City and An Gianf Province the main sites for prawn culture in the region. The results showed that prawn farming area in An Giang and Can Tho in 2005 was 376ha and 747ha respectively. Using the system most of farmers applied one crop of prawn between April and December and one crop of rice between January and April. Farm sizes range from 0.7 to 1.0 ha. Prawn postlarvae from hatcheries were used for shocking at average density of 8 inds/m. Prawn were fed mainly with commercial pellets for the first month and followed with fresh food such as golden snail trash fish and paddy crabs in the following months. Water was exchanged weekly during the culture period of 6-7 months. The average yield of prawn was 1 135 kg/ha/crop and gave net income of VND48 788 000 ha/crop. The survey indicated that the alternate rice-prawn farming system has a great economic potential for development in the region.
