Top 10 Most Common Tilapia Myths

Tilapia Myths

Tilapia is one of the most popular farmed fish in the world, providing an affordable and tasty source of protein

There are many misconceptions and myths surrounding this fish. Here, we debunk the 10 most common tilapia myths with facts.

Myth 1: Tilapia Eat Poop

This is perhaps the most prevalent myth about tilapia. It stems from their ability to eat algae and the fact they are sometimes farmed in waste ponds.

Fact: Tilapia are primarily herbivorous or omnivorous. They eat algae, aquatic plants, insects, larvae, worms, and zooplankton. They do not directly consume feces. While they can survive in sewage ponds, they mainly extract nutrition from the algae.

Myth 2: Eating Tilapia is Worse Than Bacon

Some sources have claimed that eating tilapia is worse than eating bacon or a hamburger due to the fish’s inflammatory potential.

Fact: Dietary studies show this is patently false. A 3.5-ounce serving of tilapia has just 3 grams of total fat, 1 gram of saturated fat, and 82 mg of cholesterol. 

In contrast, the same amount of bacon has 9 grams of fat, 3 grams of saturated fat, and 23 mg of cholesterol. Tilapia is the healthier choice.

Myth 3: All Tilapia Are the Same

Many people lump all tilapia together as a single fish species, but this could not be further from the truth.

Fact: Tilapia is not a species – it refers to a group of over 100 fish species. Popular farmed tilapia include Nile, Blue, Mozambique, Wami, and Zanzibar tilapia. Each has a different size, appearance, temperature tolerance, and flavor characteristics.

Myth 4: Hybrid Tilapia Are Bad

Some wrongly believe that hybrid tilapia crosses between two different tilapia species are somehow dangerous or inferior.

Fact: Responsibly farmed hybrids like Blue Nile tilapia are nutritionally identical to non-hybrid tilapia. Hybridization combines desirable traits like fast growth and disease resistance to improve aquaculture production. There are no health risks specific to hybrid tilapia.

Myth 5: Farm-Raised Tilapia is Unhealthy

Many question the nutritional value of farm-raised tilapia compared to wild-caught fish.

Fact: Farm-raised tilapia is a nutritious choice full of protein, vitamins, and heart-healthy fats:

  • High in protein: 26 g per fillet serving
  • Rich in B12, B6, niacin, selenium
  • Omega-3 fatty acids like EPA and DHA
  • Source of potassium, phosphorus, and iron
  • Low in mercury and other contaminants

Myth 6: Tilapia Farming is Not Eco-Friendly

Some believe tilapia aquaculture harms the environment.

Fact: When done responsibly, tilapia farming has minimal environmental impact:

  • It uses less land and water than other animal protein sources
  • Fish waste can be used to grow agricultural crops
  • Most farms use contained recirculating systems
  • An herbivorous diet does not require wild fish for feed

Myth 7: It’s Unsafe to Eat Tilapia

There is a perception that it is dangerous or unwise to eat tilapia.

Fact: Tilapia from reputable sources in the U.S., Canada, EU, and other regulated regions is completely safe to eat. It contains as few contaminants as other popular seafood. 

Very rarely imported tilapia from China or Taiwan has tested positive for banned chemicals. Always check the country of origin.

Myth 8: Tilapia Are Not Real Fish

Some mistakenly believe that tilapia are not natural fish species.

Fact: Blue tilapia originated in the wild in the Middle East and Africa. Nile tilapia also originated from wild tilapia in Africa. 

They have been adapted for efficient aquaculture through selective breeding while retaining their natural fish genetics. Other wild tilapia species are also farmed.

Myth 9: Tilapia Tastes Bad

A common complaint is that tilapia lacks flavor or tastes ‘muddy.’

Fact: Fresh, high-quality tilapia has a mild, sweet flavor. The taste largely depends on the quality of the fish and the preparation method. Opt for fresh, responsibly farmed tilapia. Flavor it with spices, herbs, and sauces, or use it in tacos, fish cakes, etc.

Myth 10: It’s Dangerous to Eat Chinese Tilapia

More accurately, this myth should refer to Chinese tilapia.

Fact: Lax regulations have resulted in some Chinese tilapia containing banned antibiotics and pesticides. For this reason, seafood watch lists recommend avoiding tilapia imported from China. 

Tilapia from North America, EU, South America, Australia, and elsewhere is produced under strict regulations that make it completely safe. Always check the origin.


These are some of the most prevalent tilapia myths that unfairly tarnish the reputation of this delicious, nutritious, and sustainable fish choice. 

By learning the facts, you can make informed seafood choices and safely enjoy the many benefits of responsibly farmed tilapia.
