A complete guide to Vietnam's pangasius-farming business

Have you ever wondered, "What is Vietnamese white fish actually like?"

Pangasius (basa), which you see in the frozen section of the supermarket. You know it's cheap, but you're not quite sure about its quality or how it's produced—many people have this question.

This article explains the overall picture of the pangasius business, from farming methods in the Mekong Delta to the global export structure and quality issues and countermeasures.

What is pangasius? Sorting out the difference from basa

Pangasius is a freshwater fish in the family Pangasiidae of the order Siluriformes (catfish). In Vietnam it is known as "ca basa (Cá Basa)" and "ca tra (Cá Tra)," and in the Japanese market it is often distributed under the name "basa."

Strictly speaking, basa (Pangasius bocourti) and tra (Pangasius hypophthalmus) are different species. Most of what circulates on the world market today is tra (P. hypophthalmus), and the name basa is used as a commercial umbrella term.

On Japanese food labels it is written as "pangasius" or "basa." It is becoming established as an ingredient for fried dishes and hot pot.

Why the Mekong Delta became the center of farming

Almost all of Vietnam's pangasius farming takes place in the Mekong Delta region. An Giang Province, Dong Thap Province, and Can Tho City are the three major producing areas.

The reasons the Mekong Delta is suited to it are clear.

Abundant water resources and flow rate

The Mekong River maintains a water temperature of 26 to 30°C throughout the year. This temperature range is optimal for pangasius growth. In addition, the river's flow naturally supplies dissolved oxygen to the water, making high-density farming possible.

Low-cost feed procurement

The Mekong Delta is also a major rice-producing region. The bran and broken rice generated during milling can be repurposed as feed, leading to cost reductions. In recent years there has been a shift toward formulated feed, but having a base that can make use of local agricultural by-products is a strength.

Concentration of infrastructure

Seafood processing plants, freezing and refrigeration facilities, and access to export ports are also in place. A system that can efficiently transport processed products from Can Tho City to the main ports in the south has been developed.

How farming works: from pond to table

The pangasius farming cycle is relatively short, characterized by a fast turnover of revenue.

From fry production to shipment

Fry are mass-produced at hatchery centers. Specialized seedling producers are concentrated in the Mekong Delta, making stable supply possible.

Once the fry are moved to the farming ponds and raised, they reach shipping size (700 g to 1 kg) in about 6 to 8 months. This fast growth rate is one of its excellent traits as a farmed fish.

A one-hectare farming pond is said to be capable of yielding 200 to 300 tonnes per year. This is a high production density even compared with salmon or tilapia.

The flow of processing and export

After harvest, the fish go straight to the processing plant. Vietnam's seafood processing plants basically operate 24 hours a day, and a flow of filleting → quick freezing → packing → export has been established.

An export structure that dominates the world market

Vietnam is the pangasius world's largest exporter. In 2023, export value reached about US$1.8 billion, with the EU, the United States, and China as the main markets.

Distribution of export destinations

In the Japanese market, demand has grown in recent years as an ingredient for food-service fried dishes. Pangasius is often used in the "fried white fish" of izakaya and set-meal chains.

Structural factors behind the low price

The reasons pangasius is cheaper than competing fish species come from several overlapping factors.

First, as noted above, the growth cycle is short. Second, labor costs in Vietnam are low compared with the West and Japan. Third, processing residues (bones, skin, and viscera) can also be sold as fish meal and fish oil, so the recovery rate on costs is high.

The export price of fillets for the EU often hovers around US$2 to 3 per kilogram, and compared with salmon (US$10 to 15) or cod (US$4 to 6), its price competitiveness is clear.

The reality of quality issues and the industry's response

For all its low price, pangasius is also a fish that has faced a range of criticism on quality.

Issues raised in the past

Excessive bleaching and glazing

Bleaching with hypochlorous acid or hydrogen peroxide to emphasize whiteness came under scrutiny. Cases have also been reported where excessive glazing (a coating of ice) aimed at adding weight led to a large loss of weight after thawing.

Antibiotic residues

In high-density farming environments, disease breaks out easily, and there was a period when antibiotic use became routine. There were also cases where residual antibiotics were detected in exports to the EU and import suspension measures were taken.

Environmental burden

There are also voices pointing to the problem of wastewater discharge into the Mekong River and the impact on ecosystems. From a sustainability standpoint, there have been moves by European retailers to reconsider their sourcing.

Quality improvements the industry is pursuing

In response to criticism, the Vietnamese government and industry groups have strengthened their measures.

The spread of certification systems

A growing number of producers are obtaining ASC (Aquaculture Stewardship Council) certification and GlobalG.A.P. certification. Because certification requires records of the rearing environment, water-quality management, and antibiotic use, it is helping to raise quality across the board.

At present, the area of ASC-certified pangasius farms in Vietnam has reached About 30% of the total, and the certified share is rising year by year.

Tighter rules from VASEP (the Vietnam Association of Seafood Exporters and Producers)

VASEP has made self-inspection of processing plants mandatory and enforces antibiotic testing before export. Sanctions for violators have also been put in place, aiming to raise standards across the industry.

Building traceability

Efforts to require lot-by-lot tracking records from the farming pond through to export are also advancing. More products now let you check origin information via a QR code.

The current state of pangasius in the Japanese market

Import volumes to Japan gradually increased from the 2010s and now flow mainly through food-service channels.

Awareness as a household frozen food is still not high, but in the cost-conscious restaurant industry it is becoming established as an ingredient for "white fish."

The points Japanese importers emphasize are as follows.

• Thawing yield: whether the glaze ratio is appropriate (10 to 20% is the guideline)
• Color and smell: whether bleaching has been used, and the state of freshness management
• Presence of certification: the status of ASC and HACCP certification
• Price stability: the risk of fluctuations in exchange rates and raw-material costs

Japan's food-hygiene standards (pesticide residues and additives) are especially strict among ASEAN countries, and processors on the Vietnamese side are working to meet Japan-specific specifications.

The future outlook for the pangasius business

Against the backdrop of rising global demand for protein, demand for pangasius is expected to expand over the medium to long term.

Of particular interest are the Middle East and Africa markets. With population growth and raising incomes demand for affordable animal protein is surging, and Vietnamese pangasius is meeting that demand.

On the other hand, the effects of climate change are altering water temperatures and salinity in the Mekong Delta, posing a risk to the farming environment. Changes in water flow from dam construction upstream are another concern.

Whether it can balance sustainability with price competitiveness will determine the future reputation of Vietnamese pangasius.

Summary

Pangasius farming is a business that has grown into the world market by drawing on the natural conditions of the Mekong Delta and a low-cost production structure.

It once faced criticism over quality issues, but with the spread of certification systems and the development of traceability, its reliability is steadily improving.

In the Japanese market, adoption is advancing mainly in food service, and it is a fish species worth watching for those involved in food imports. Selecting growing regions and processors and clarifying quality standards are the keys to stable sourcing.
