Background History

Swai fish and catfish have a rich history as dietary staples in various cultures around the world.

Swai, scientifically known as Pangasius hypophthalmus, originates from Southeast Asia, particularly Vietnam.

Catfish, on the other hand, includes various species and is native to North America, with the channel catfish being the most common choice for consumption. Both fish types have found their way into international cuisines, making them accessible options for diverse culinary creations.

Here is a brief history of catfish introduction and use in the USA compared to swai fish:

History & Origin of Swai Fish

Until 2003, Swai fish was considered a catfish. Which it obviously isn’t— despite the similarities they are both different types of fishes.

In 2003 the US Food and Drug Administration made it illegal to sell any fish other than the ones from the family of Ictaluridae, under the name of catfish.

This meant Vietnamese catfish could no longer be sold as catfish, as it doesn’t belong to the Ictaluridae family.

It belongs to the Pangasiidae family – so people now started addressing it with other names.

Striped Basa, panga, pangasius, Vietnamese catfish, tra, siamese shark, iridescent shark, cream dory were some of the names given to Swai fish over the years.

Until the more common and popularly used term, Swai fish was introduced in the market.

History & Origin of Catfish

Catfish is native to North American rivers and has been a popular food source for centuries.

In conclusion, while catfish has been a popular food source in the United States for centuries, swai fish is a relatively new addition to the American diet. Both types of fish have their unique characteristics and are enjoyed by many individuals. However, it is essential to be aware of potential concerns regarding the presence of heavy metals, such as mercury, in both catfish and swai fish[4][5].

Environmental and Sustainability Factors

Here is how environmental and sustainability factors impact swai fish and catfish farming.

Sustainability, better farming practices, and concerns by consumer are now also shaping demand for both fishes as the impact of these factors on both fishes vary greatly

So how are these factors influencing the consumer’s choice between both types of fish?

Here are the detailed Environmental and Sustainability Factors in Farming Swai Fish and Catfish

 Swai Fish Farming:

Swai fish, primarily sourced from Southeast Asia, has faced scrutiny due to concerns related to environmental and sustainability issues associated with its farming practices. Some of the key factors include:

  1. Water Quality and Pollution: Intensive swai fish farming in certain regions can lead to water pollution due to waste accumulation and the use of chemicals. This can have negative effects on local ecosystems and biodiversity.
  2. Feed Conversion Efficiency: Swai fish often require substantial amounts of fishmeal and fish oil in their diets, contributing to overfishing of smaller fish species and placing pressure on marine ecosystems.
  3. Aquaculture Practices: In some cases, swai fish farms have been criticized for suboptimal aquaculture practices, including improper waste management, disease control, and use of antibiotics.

Here are more details about swai fish farming practices:

Potential Reasons to avoid Swai fish:

Swai fish is often fed rotten feed and kept in undesirable water conditions.

Below are some of the top 5 practices regarding Swai fish you should be aware of especially if you have concerns and evaluating healthier options of fish like Catfish:

#1:      Bacterial Contamination:

Swai fish is prone to immense bacterial growth. Researchers over the years have found the presence of bacteria like E.coli and Vibrio Bacteria, medically termed as Vibrio spp. This bacteria in particular is known to cause shellfish poisoning and can be hazardous if the Swai fish is consumed raw or undercooked.

#2:          Illegal Practices In Fish Farming:

Swai fish is popularly farmed in Vietnam, in the polluted waters of the Mekong River. Which also happens to be one of the world’s most polluted water bodies.

But how do the fish survive in such conditions?

Pangasius or Swai fish naturally have the tendency to thrive well even in nasty water conditions, unlike other freshwater fishes.

They are thrivers. They feed on whatever food is available. The farmers use this to their advantage and make extra profits by often feeding the fish with rotten foods that aren’t advisable.

But little do they know that you are what you eat.

Swai fish is made to feed on Rice bran, along with soybean and canola, none of which are healthy diet options for fish. The soy and canola products are commonly genetically modified, which is a controversial practice.

Now if this isn’t harmful to the fish, I don’t know what is.

Also, these hormones travel through their bodies to the consumers, with the potential to create havoc, especially on reproductive systems.

Not only this, Swai fish are farmed in overpopulated and crowded environments, which affect their health and growth. They are then administered high doses of hormones to make them achieve maturity faster, at less than half the usual time. Overcrowded ponds also cause the fish to go under stress and result in diseases.

#3:   Use of Heavy Antibiotics:

Due to the sleazy conditions, the fish are kept in, diseases are common. For which administration of heavy antibiotics is a norm. These antibiotics run in their bloodstream and settle in their flesh. Making the flesh contaminated.

#4:     Environmentally Hazardous:

Due to the unhealthy conditions of the swai fish breeding farms, it is a common practice to use pesticides, disinfectants and other chemicals. These contaminants affect the fish’s meat and its consumer.

But that’s not all, the contaminated water is sooner or later released into the rivers and seas. This improper disposal of water is hazardous for the environment.

#5:    High Mercury Levels:

Swai fish also contains high levels of mercury. A study carried on imported, frozen Swai fish concluded that over 50% of the products contained mercury and other chemical levels far above the World Health Organizations limit.

As the demand for more sustainable food options grows, consumers are becoming increasingly conscious of the environmental and ethical implications of their food choices. This awareness is influencing their decisions when it comes to choosing between swai fish and catfish:

  1. Certifications and Labels: Consumers often look for certifications like the Aquaculture Stewardship Council (ASC) label, which indicates that the fish has been farmed in a responsible and sustainable manner. This can impact their choice between swai fish and catfish.
  2. Transparency and Traceability: Consumers value transparency in the sourcing and production of their food. Catfish farming in regions with better regulations and practices might be more appealing to environmentally conscious consumers.
  3. Local and Domestic Sourcing: Opting for domestically produced catfish, subject to more stringent regulations, can align with consumers’ preferences for supporting local industries and sustainability efforts.
  4. Educated Consumer Choices: As consumers become more informed about the environmental impact of fish farming, they are likely to lean towards options that demonstrate commitment to sustainable practices, which can impact their choice between swai fish and catfish.

VERDICT: In conclusion, environmental and sustainability factors significantly influence the perception and choice between swai fish and catfish.
While swai fish farming has faced environmental concerns, catfish farming in regions with better practices and regulations is showing efforts toward sustainability.
Consumer demand for transparency, certification, and sustainability is driving change in the industry and shaping the choices consumers make when it comes to seafood consumption.

Health Benefits

Let’s now explore the health benefits of consuming swai fish and catfish with respect to these minerals:  Omega-3 fatty acids, protein content, vitamins. We also discuss the potential health concerns, such as mercury levels or allergies in both fishes

Potential Health Concerns and Considerations:

Mercury Levels:

One concern with certain types of fish is mercury contamination, which can be harmful, especially for pregnant women and young children.

Although both swai fish and catfish are considered low in mercury compared to larger predatory fish, Swai fish is still predominantly more associated with higher mercury risk than catfish as shown by the stats below:

A study carried out on imported, frozen Swai fish concluded that over 50% of the products contained mercury

A 2011 study using government-collected veterinary drug violation data from 2000 to 2009 across four inspecting bodies (European Union (E.U.), United States (U.S.), Canada, and Japan) found that Asian seafood products, including shrimp and prawns, catfish (or fish sold as catfish) were most frequently in violation of veterinary drug residue standards. Specifically, the study also found Vietnam had the greatest number of violations among exporting countries.

As we have already mentioned, Swai fish is largely farmed and imported to the US from Vietnam.

While this may not be enough proof to say that one shouldn’t be risking one’s life eating fish like Swai, it does provide a basis to consider other options.

However, one can take the precaution of sourcing fish from reputable and sustainable sources to further mitigate potential mercury exposure.


Some individuals may have allergies to seafood. It’s important to be aware of any allergies and consume fish cautiously. If you suspect an allergy, consult a healthcare professional for appropriate testing and guidance.

VERDICT: Swai fish and catfish offer health benefits in terms of Omega-3 fatty acids, protein content, and vitamins.

While swai fish might have a milder Omega-3 profile, catfish provide a higher protein content, making it appealing for those seeking to increase protein intake.

Both fish types are good sources of B vitamins. Addressing potential health concerns such as mercury levels and allergies requires responsible sourcing and individual awareness.

Incorporating a variety of seafood options into a balanced diet can contribute to overall health and well-being.

Reasons to Reconsider Swai Fish

Swai fish has come under scrutiny due to several factors that raise concerns about its safety and sustainability. Here are five key reasons people consider other options:

  1. Bacterial Contamination: Swai fish is susceptible to bacterial growth, including harmful strains like Vibrio spp. Consuming raw or undercooked Swai fish may lead to health risks associated with these bacteria.
  2. Unsustainable Farming Practices: Swai fish is commonly farmed in polluted waters, leading to overcrowding and the use of hormones and antibiotics. These practices compromise fish health and result in contamination of the fish’s flesh.
  3. Environmental Impact: Polluted water conditions in Swai fish farms often necessitate the use of pesticides and chemicals. Improper disposal of contaminated water further harms the environment.
  4. Mercury Content: Studies have shown that Swai fish can contain elevated levels of mercury, exceeding recommended limits set by health organizations.
  5. Rotten Feed and Poor Conditions: Swai fish are often fed subpar diets, contributing to their potential contamination and compromised nutritional quality.

 Exploring Alternatives: Catfish

Catfish emerges as a viable alternative to Swai fish, offering both nutritional benefits and a more sustainable choice. Here’s why:

  • Nutritional Comparison: Catfish is a rich source of omega-3 fats, with a similar protein content to Swai fish. It provides essential nutrients like selenium, vitamin B12, and niacin, making it a healthier option overall.
  • Taste and Texture: Catfish shares a flaky texture and a sweet aftertaste with Swai fish. This similarity makes catfish a versatile substitute in various recipes.
  • Affordability: While slightly pricier than Swai fish, catfish offers better nutrition and environmental considerations, justifying the cost difference.
  • Farming Practices: Catfish farming in the US prioritizes healthier conditions and is environmentally friendlier compared to Swai fish farming in polluted waters.
  • Food Intake: Catfish have a more natural diet and are not subject to the same degree of hormonal manipulation as Swai fish, contributing to better overall quality.

 Recommendation: Opting for a Healthier Choice

In the Swai fish vs catfish debate, catfish emerges as the preferable option. Its higher nutritional value, better farming practices, and reduced environmental impact make it a more responsible choice for health-conscious consumers.

    • Hello Merlin,
      I guess the simple reason would be that they do not have any reason not to.
      We can all take solace from knowing that usually all products inspected and allowed into the US by the FDA adhere to the strict regulatory requirements otherwise they would not be allowed in.
      I hope this helps.
