Since 2000, the country

has seen a rapid increase in pangasius aquaculture production resulting in consolidation of a number of farms although significant production also remains at the household level (i.e., family owned and operated farms). Pangasius, however, is not a species farmed by poor households even in cases where farm size is small, and, therefore, cannot be considered small scale in terms of a ‘quasi-peasant activity׳ [5: 575]. Vietnam׳s seafood sector has been plagued with perceptions of poor management including allegations that catfish are farmed in dirty water and are unsafe for human consumption [36], and the recent discovery of packers injecting agar-agar, a plant-based gelatin, into shrimp to raise its weight pre-export [37]. Japan has Quizartinib chemical structure also begun testing shrimp from Vietnam for chemical GSK1120212 substances and antibiotic residues [38], illustrating a lack of confidence in how Vietnam regulates its seafood

sector. This, along with the government׳s desire to maintain and increase international exports, helps to explain Vietnam׳s growing interest in certification. There are a number of farms and companies that have obtained certification in Vietnam, predominantly by the ASC, and mainly for pangasius. For example, ASC has certified 43 groups of pangasius producers since 2011 [39], and the Global Aquaculture Alliance (GAA) through its Best Aquaculture Practices (BAP) has certified 8 pangasius farms. The Vietnamese government announced in 2014 that all pangasius farms and companies need to be certified by one of the main standards operating in Vietnam by 2016 [40]. A few producers are certified for other farmed species such as tilapia (ASC), white leg shrimp (GLOBALG.A.P.) [38] and [40], and shrimp generally (BAP). At this point in time, mainly larger producers have been certified. Recent work on food standards in the pangasius sector suggests that upper middle-class farmers benefit directly from participating in such standards, whereas other

farmers (i.e., lower-middle class farmers) do not [42]. Thus, it is worth questioning the viability of standards operating in Vietnam that are being applied for small producers in the shrimp sector. Table 1 provides a backdrop for four key certification schemes operating in Vietnam, Orotidine 5′-phosphate decarboxylase GLOBALG.A.P., ASC, GAA, and VietG.A.P. GLOBALG.A.P. certifies nearly 80% of certified aquaculture globally [13], with certified products found throughout Europe and North America. The ASC has a strong presence in Europe targeting shrimp specifically with its Shrimp Aquaculture Dialogue (ShAD), GAA has a strong presence in North America and targets shrimp and feed specifically within its BAP standards, and VietG.A.P. is Vietnam׳s national certification standard, acting as an entry standard into international certification schemes like GLOBALG.A.P., ASC, and BAP. Three of the standards, GLOBALG.A.P.
