Within a 10 year period (1997–2007),80 processing plants with a combined capacity of up to 3,500 tons raw fish dailywere established, mostly in the Mekong delta. This resulted in an increase of over55-fold, from 7,000 to 386,870 tons the volume of exported fillets. Striped catfishproducts have also been exported to over 80 countries and territories (Dung 2008)(Fig. 7.4 ). Although, striped catfish has been exported mostly in fillet form, thereare more than 40 value added products have also been produced for domestic andinternational markets.7.5 Socio economical Impacts from Striped Catfish FarmingThe socio-economic impacts of the striped catfish farming may need a detail studyfor full understanding. However, the direct impact on the economic aspect can berepresented from the household income of striped catfish farmers and increasedyearly export value. During the 10-year period from 1997 to 2007, the export valuesincreased 50-fold, from US $19.7 to 979,036 (Fig. 7.5 ). The amount earned fromexport contributed about 0.84% to the GDP of Vietnam or 21.7% of 3.7% of thecontribution from the aquaculture sector in 2006 to the GDP.Striped catfish farming itself creates livelihood opportunities not only to thosedirectly involved in farm activities, but also for many other people who work aslabor in related sectors. Striped catfish farming activities initiated the developmentof fillet processing, feeds, drugs, and chemicals industries. These related industrieshave provided livelihood opportunities for a large number of people, a significantproportion of those are rural women.
