“…Over the last decade the farming of striped catfish has taken primacy over the basa variety as it proved easier to spawn and faster growing. In addition, its quality attributes are better (Phuong & Oanh, 2010), and now it accounts for almost all of farmed pangasius in Vietnam.…”

We estimate the causal effect of food standards on Vietnamese pangasius farmers' wellbeing measured by per capita consumption expenditure. We estimate both the average effects and the local average treatment effects on poorer and richer farmers by instrumental variable quantile regression. Our results indicate that large returns can be accrued from food standards, but only for the upper middle-class farmers, i.e., those between the 50% and 85% quantiles of the expenditure distribution. Overall, our result points to an exclusionary impact of standards for the poorest farmers while the richest do not apply standards because the added gain is too small.

“…For instance, Vietnam is the largest production country of sutchi catfish in Southeast Asia [6]. There, in 2007, 1,200,000 tons of catfish was produced of which 95-97% was sutchi catfish [7]. A total of 387,000 tons of fillets of sutchi catfish was exported to over 80 countries [7].…”

Feeding behavior under dark conditions in larvae of sutchi catfish Pangasianodon hypophthalmus

et al. 2010

Sutchi catfish Pangasianodon hypophthalmus hatch with morphologically immature sensory organs; however, sensory organs develop rapidly with larval growth. Two-day-old larvae commenced ingesting Artemia nauplii. The larvae displayed many taste buds on the barbels, the head surface, and in the buccal cavity. Other sense organs were also well developed at this stage. Feeding experiments revealed that 2-day-old larvae ingested Artemia under both light and dark conditions, moreover, the larvae could ingest frozen dead Artemia. The ingestion rates for 4-and 7-day-old larvae were significantly higher under dark conditions than under light conditions. The rates using frozen dead Artemia were mostly higher than the rates using live Artemia. Therefore, feeding behavior under dark conditions is most likely not mediated by visual or mechanical senses, but rather by chemosensory senses, such as taste buds. Larval fish are vulnerable to predators; thus, if they can search for and eat food at night, they can avoid diurnal predators. The behavior observed here appears to represent their survival strategy. Moreover, these results suggest a new possibility that sutchi catfish larvae can be reared under dark or dim light conditions in order to improve survival and growth rates as in the case of African catfish Clarias gariepinus.

“…The majority of commercially produced aquatic species in the delta are striped catfish Pangasianodon hypophthalmus and penaeid shrimp (Penaeus monodon and Litopenaeus vannamei) (De Silva & Phillips 2007, Phuong & Oanh 2010, De Silva & Phuong 2011. Tilapia products are mainly destined for local consumption and have contributed substantially to livelihoods, food supply, and poverty alleviation (Hung 2010, Nguyen & Vo 2011.…”

The Mekong Delta in Vietnam is one of the most productive aquaculture regions in the world, in which the red tilapia (Oreochromis spp.) industry is a small-scale industry that mainly supplies local markets in the delta region. Little is known about the frequency of mortality events and health management in this sector. We describe red tilapia floating cage production systems in the Mekong Delta, Vietnam, for the purposes of quantifying mortality and associated production factors, and describing practices that may influence pathogen introduction and spread to and from farms. In July 2014, approximately 50 red tilapia farmers from 4 provinces (201 farmers in total) were randomly selected and interviewed. Median overall perceived mortality (PM) within a production cycle was 35%. Overall PM was found to be affected by province (p < 0.01), age of farmers (p = 0.01), anticipated main reason for PM in the first 2 wk (p = 0.03), most common market for the fish (p = 0.02), and whether farmers recorded stocking information (p = 0.01). Based on the interviews, we describe and discuss processes that potentially affect pathogen introduction and spread on these farms, such as movements of live and dead fish, distances between farms, mechanical transmission, and biosecurity practices such as treating fish before stocking, using disinfectants, and sharing equipment, and harvesters' movements. This study provides fundamental understanding of red tilapia aquaculture management in the Mekong Delta, and describes management factors that could become important in the event of disease outbreaks.
