dc.description.abstractThe purpose of this thesis is to measure the mean technical efficiency of improved extensive shrimp farming in Cai Nuoc and Dam Doi districts, Ca Mau Province, Vietnam. Data Envelopment Analysis Input-oriented variable return to scale were used in this thesis and estimating technical super-efficiency was regressed to the pond area, farmer experiences, black tiger shrimp, mud crab stocking density and education of farmers. Technical efficiency of observation farms was the identified determinant factor, results indicated that pond area, experience and education of the owners of the shrimp farms were the mainly positive factors that influence efficiency of improved extensive shrimp farming in both districts. Nevertheless, only in Dam Doi district shrimp stocking density have a negative relationship with technical efficiency. A comparison between the technical efficiency results of the two districts showed that the farms in Cai Nuoc were more highly efficient than farms in Dam Doi District. To improve technical efficiency, the government should conduct training on techniques in shrimp polyculture, establish farmers’ organization should assist to help farmers share their experiences and provide mutual help. In addition, extension officers should organize regular training courses in shrimp polyculture model to help farmers in both districts increasing productivity.en
