dc.description.abstract | Shrimp aquaculture systems vary from primitive (extensive/
improved extensive) to more industrialized (intensive/semiintensive) farms, and the impacts of environmental shocks
may differ between them. This article applies the Cobb–
Douglas stochastic production frontier function to evaluate
the determinants that impact the inefficiency of these
intensive and extensive systems in Vietnam. Data is from a
survey of 436 white-leg shrimp (Litopenaeus vannamei)
farms in the Mekong Area. Our findings show that farmers
with self-reported experiences of drought have higher production efficiency, while experiences of irregular weather reduce
efficiency. In addition, education and feeding practice/stocking
density adjustment measures increase extensive efficiency.
Furthermore, longer crop duration impacts the two systems
differently, increasing intensive farm efficiency but decreasing
extensive farm efficiency. Interestingly the efficiency effects
differ for the two technologies, with two exceptions; efficiency increases for both locations further from the sea and
decreases with disease occurrence. | en_US |
