This paper aims to investigate and compare economic and environmental perspectives of two shrimp systems in Xuan Thuy National Park (Vietnam). The primary data was collected in 2016 through interviewing 30 intensive shrimp farmers and 33 extensive shrimp farmers in the protected area. Economic indicators reveal that the intensive production incures total costs of 451×106 Dong ha-1 which is 18 times higher compared to extensive farming (24×106 Dong ha-1). Among costs of intensive culture, feeds including pellet feeds, supplements and some antibiotics are the dominant items comprising 58% (260×106 Dong ha-1), followed by white leg shrimp spawns and electricity (12% and 7% respectively). In the extensive culture, family labour, giant tiger shrimp and crab spawns are the important input costs (respectively 28% and 27%). Intensive ponds require huge capital for feeds, hired labour, spawns, electricity, gasoline, sand and lime, while extensive farms use much less pellet feeds, gasoline, lime, and no electricity and sand. Intensive shrimp farming brings higher net profit per hectare of land (233×106 Dong) than extensive farms do (32×106 Dong). Nevertheless, some economic efficiency indicators illustrate that the return on working capital of extensive farms is 5 times as much as of intensive ones.
