“…Shrimp farming is one of the fastest growing economic activities in the Asia–Pacific region (Wolanski, Spagnol, Thomas, Moore, Alongi, Trott & Davidson 2000; Raux & Bailly 2002; EJF 2004) and experienced spectacular growth over recent decades (Thornton, Shanahan & Williams 2003; EJF 2004). In Vietnam, extensive farming of shrimp started about 100 years ago (Nhuong, Luu, Tu, Tam & Nguyet 2002) and was characterized by low shrimp yields (100–400 kg ha −1 year −1 ) (Binh & Lin 1995).…”

Consecutive failure of the improved extensive shrimp farming system has deterred the economy of some coastal areas in Vietnam. To investigate pond physicochemical characteristics, a monitoring scheme was performed in the Cai Nuoc district of Southern Vietnam. Results show that the system was not optimal for shrimps.While ponds were not contaminated by organic loadings or major nutrients (N, P) and salinity and pH were most optimal for shrimp, more than 37% of dissolved oxygen (DO) measurements were lower than recommended. In the early morning hours, DO measurements were even much lower (0.84^2.20 mg L À 1 ). Sulphate (SO 4 2 À ) concentrations were most within the acceptable range. Total suspended solids (TSS) were above the acceptable limit (o50 mg L À 1 ). Iron, alkalinity and hydrogen sulphide were also higher than recommended. Pond sediment was anaerobic (redox potential À 422 to À 105 mV) and contained high amounts of organic matter (9.842 1.96%). Lethal DO levels, high TSS and anoxic sediment are the drawbacks in this system. Suggested measures to improve pond conditions are (1) allowing sedimentation before ¢lling culture ponds, (2) covering dikes, (3) including no-culture breaks between shrimp crops, (4) drying pond bottom, (5) removing sediment and (6) controlling pond's vegetation.

“…In 2000, government resolution No. 09/2000/NQ‐CP enhanced this expansion by allowing farmers to convert low‐productivity coastal saline paddy fields into shrimp ponds (Nhuong et al , ; Raux et al , ). Although technological innovation led many Asian coastal nations to a boom in industrialised (export‐led) shrimp farming in the 1980s (Hall, ), Vietnam was one step behind, and upgrading in terms of production systems and technologies was very slow to spread.…”

Multifunctionality and agrarian transition in alternative agro‐food production in the global South: The case of organic shrimp certification in the Mekong Delta, Vietnam

Processes of globalisation in the conventional food provision system have had widespread negative impacts on small-scale farmers. Yet, alternative food networks, which are characterised by more sustainable production/consumption practices and fairer trade relations, have increasingly been 'going global' and, in the process, have been integrating small-scale farms in the South. One such high-value export-led commodity is certified organic shrimp. International third-party certification schemes are becoming popular as a tool to verify the intangible attributes of such commodities. Using concepts of multifunctionality and agrarian change, this paper examines the implications of introducing an international environmental certification programme to a site where the 'peasantry' has been preserved and has limited integration in the global agro-food system. Drawing on a case study that examines the first certified organic shrimp production project in Vietnam, this paper concludes that the current movement towards post-productivism in the global North has potential to keep local farming practices in the global South by justifying the value of peasant-like production methods through international certification. As a result, the development path of agrarian transition might be reshaped into a form not necessarily pursuing industrialisation. This leads to the new interpretation of pre-and post-productivism beyond the North and South divide.

“…With culturing black tiger prawn (Penaeus monodon) for the past 20 years, Vietnam has become the global export leader with an annual production of more than 300,000 tons (Vietnamese Ministry of Fisheries (VN-MoFI) 2006;FAO 2009;Raux et al 2006). Black tiger prawn is one of the most widely cultured aquaculture species in Vietnam, especially in the Vietnamese Mekong Delta (VN-MKD).…”

Production and economic efficiencies of intensive black tiger prawn (Penaeus monodon) culture during different cropping seasons in the Mekong delta, Vietnam

Production management of intensive prawn farming strongly differs between dry and wet season in terms of availability and quality of prawn seeds and water quality. Secondary data implied that prawn seed batches from the market had a total pathogen infection rate of 53%, predominantly caused by 37% white spot syndrome virus (WSSV), 19% monodon baculovirus (MBV) and 4% yellow head virus (YHV). Pathogen-free seed batches averaged to 52% during the dry season compared to the wet season (42%). Survey revealed average stocking density of 17 PL m -2 with a survival rate of 55%, a crop yield of 2,470 kg ha -1 crop -1 and a net income of 6,768 USD ha -1 crop -1 . Average production cost amounted to 3.4 USD kg -1 , and feed cost accounted for 58% of the production cost. Technical efficiency with respect to prawn yield and survival rate was higher during the dry season than the wet season. The probability of yield loss was 15.6 times higher in the wet than in the dry season. A positive net income can be generated for farms operating in the dry season using new ponds and performing pathogen laboratory tests on prawn seeds before stocking.
