Productive Efficiency of Intensive White-Leg Shrimp Farming Households in Phu Yen Province

Abstract
Shrimp is the major commodityin the annual export turnover of Vietnam. This paper analyzedproductive efficiencyof the intensive white-leg shrimp farming households in Phu Yen. A total of 59 shrimp farming households practicing intensive aquaculture with the area of 45 ha (about 24% of the intensive white-leg shrimp farming in Phu Yen province) were randomly surveyed. The result showedthat although the intensive white-leg shrimp farming in Phu Yen is still profitable,but the interest for investment in shrimpfarming is rather low due to high risk and high productive capital. Moreover, this aquaculture is only profitable if its negative impact on the environment is neglected. The saturation state due to open-access mechanism for aquaculture has, however, been reached. Toward a sustainable aquaculture, it requires a further revision and issuing policies that step by step endogenize the environmental costs into the production process. Farmers’supports such as technology development, technique training and credit acess are also important.
