Farming pangasius is a strong development career in the Mekong River Delta. However, this is a career that is easy to “up and downs” by some impact factor

The Mekong River Delta is the aquatic economic center of the country. In many years over, thanks to many achievements in the farming pangasius technology to become the main economy of the region. Not only brings to a great source of foreign currency, but farming pangasius also has an important role in poverty reduction and job creation for people. This is an industry that always faces difficulties, challenges from the market require continually improving the quality of breeders, cutting costs of raising, processing, and innovating products …

According to the Vietnam Association of Seafood Exporters and Producers(VASEP), because of the impact of the pandemic, the import market is impacted, the cost of material pangasius in the Mekong River Delta in the first half of this year low, fluctuating around 18,000 – 18,500 VND / kg. With this price, both the farmer and producer and process are lost, hanging pond.  This makes the demand to reduce costs in pangasius ponds even more urgent.

The real survey shows that wastage rate in pangasius ponds in recent is still high even high to 30-35%, especially some pangasius ponds have wastage rate high to 40-50% due to drop fish with high density (over 100 con/m2).

Not only that, but the farming cost also increases, Previously, the good quality of fingerlings, the breeding time only took 5-6 months to have fish reaching the standard size to export ( about 0.8 -0.9 kg/fish), Feed Conversion Rate(FCR) reached about 1.5-1.6. Therefore, the food cost in the farming process with each hectare is also increased to about 500-600 million dongs. This means that the price of each kilogram fish also increased more than 1.500-2000 dongs/kg.

According to the evaluation, success in aquaculture farming depends on many elements. In which, the most important thing is the effective management of costs in the production process, especially is food cost (accounting for over 78% in price). Ineffective feeding management such as feeding excess fish not only wastes food increases production costs but also pollutes the water environment in the pond.

While feeding fish is not enough, it makes fish develop slowly and high death rates. There are the main reasons that lead to the fail situation in aquaculture. Therefore, it is very important to study the technical aspects, establish management and develop technology solutions to reduce costs, so that the farmers can maintain and develop a sustainable pangasius farming model in the Mekong River Delta.

From 2013 to 2017, Vietnam Cleaner Production Center Co., Ltd ( VNCPC-under BK Holding- Hanoi University of Technology) has together with WWF-VN, WWF-Austria, and VASEP to implement the project ” Building a sustainable pangasius supply chain in Vietnam -SUPA” sponsored by the European Union to increase value, cut costs, reduce environmental pollution, and develop Vietnamese pangasius sustainably. One of the effective activities is the project coordinated with Fisheries Faculty – Can Tho University survey, research, test measures to cut costs in the farming stage. A series of low-cost measures have been applied such as:

– Breeding with suitable density: 40 fish/m2

– Food regime FCR: 1.44-1.48

-Adding enzyme phytase in food to enhance digestion

– Always control the quality of water supply, create ventilation for the culture surface to increase oxygen supply by creating continuous flow, spraying water …

– Controlling disease

Item Before applying After applying
FCR 1.55-1.75 1.44-1.48
Survival rate 69-82% 83-92%
Production cost (VND/kg) 20.700-21.600 18.620-19.890
Environmental quality    
pH 7.7-7.9 7.6-8.6
Oxy(mg/l) 1.2-1.8 1.7-2.9
TAN(mg/l) 0.033-4.602 0.33-3.1
H2S(mg/l) 0.019-0.035 0.01-0.02

The result is the price of farming pangasius is reduce. In which, the application of integrated measures of Resource Efficiency and Cleaner Production has helped pangasius farming businesses to bring economic efficiency while minimizing the impact on the environment, sustainable development, and increasing competition in the world market.
