Abstract
The study aimed to assess the production efficiency and electricity consuming of white-leg shrimp and black tiger shrimp of intensive and improved extensive farming systems in the Mekong Delta, in order to estimate the demand of electricity to develop the network of electricity supply and use in sustainable shrimp farming. The result indicated that the yield of white-leg shrimp cultured in lining pond was averaged 47±19 ton/ha/crop higher than that of shrimp cultured in earthen ponds (10±11 ton/ha/crop), followed by intensive system culture of black tiger shrimp with shrimp yield of 5±3 ton/ha/crop, and the lowest was the improved extensive system (0,39±0,23 ton/ha/year). White-leg shrimp cultured in lined pond consumed 3,235 kW.h/ton of shrimp (electricity cost of VND 5,085/kg of shrimp) that was higher than that of white-leg cultured in earthen pond 2,914 kW.h/ton of shrimp (VND 4,514/kg of shrimp); but lower than that of intensive black tiger shrimp 4,173 kW.h/ton of shrimp (VND 6,560/kg of shrimp); meanwhile improved extensive of black tiger shrimp did not use electricity.
