Determinants of inefficiency in shrimp aquaculture under environmental impacts: Comparing shrimp production systems in the Mekong, Vietnam

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