Tilapia is one of the most widely consumed fish in the world, but its reputation is far from spotless. While some praise it as an affordable, mild-tasting source of protein, others raise concerns about its diet, farming conditions, and nutritional value. If you’ve ever wondered what you’re really getting when you order tilapia, here are 11 things you need to know – some of which might surprise (or disgust) you.
1. Yes, Tilapia Eats Poop
It might sound like a bad joke, but it’s true – tilapia has been known to eat feces. In some large-scale fish farms, particularly in certain Asian countries, tilapia are fed animal waste as a cheap alternative to traditional fish feed. The idea is to cut costs and maximize yield, but it raises serious concerns about hygiene and food safety.
Not every tilapia is raised this way, of course, but if you’re eating imported tilapia from regions with lower farming standards, there’s a good chance your fish had a questionable diet before landing on your plate.
2. It’s One of the Most Farmed Fish in the World
Tilapia’s ability to thrive in crowded conditions makes it a favorite for fish farms. Unlike more delicate species, tilapia can be packed together in large numbers without suffering too much stress or disease. This high-density farming means more fish can be raised in a small space, making tilapia one of the cheapest and most widely available seafood options.
The downside? When fish are crammed together, waste accumulates quickly, and the risk of disease increases. Farmers may use antibiotics and chemicals to prevent outbreaks, which is another factor to consider when choosing farmed tilapia.
3. It’s a High-Yield Fish
One of the reasons tilapia is so popular in the seafood industry is that it provides a high meat-to-bone ratio. This means that compared to many other fish, a larger percentage of the tilapia’s body is edible. The small head and broad body make it particularly efficient for commercial production, where maximizing usable meat is a priority.
For consumers, this means more value per pound – but it also contributes to the mass farming of tilapia, sometimes at the expense of quality.
4. Tilapia Is Loaded with Protein
If you’re looking for a high-protein meal, tilapia delivers. An 8-ounce serving contains over 60 grams of protein, making it an excellent option for muscle building and general nutrition.
However, while it’s packed with protein, tilapia lacks some of the beneficial fats found in other fish. Unlike salmon or mackerel, which are rich in heart-healthy omega-3 fatty acids, tilapia has relatively low levels of these essential fats.
5. It’s One of the Most Economical Fish You Can Buy
Tilapia is cheap, and that’s one of its biggest selling points. While seafood prices can be notoriously high, tilapia remains one of the most budget-friendly options on the market.
For those on a tight budget, tilapia offers a way to incorporate fish into the diet without breaking the bank. While it might not be the most nutrient-dense seafood choice, it’s still a better alternative than ultra-processed fast food.
6. Tilapia Is Extremely Mild-Tasting
Not a fan of strong, fishy flavors? Then tilapia is probably right up your alley. It has an incredibly mild taste, which is one of the reasons it’s so widely consumed. Many people who dislike seafood find tilapia to be a more palatable option.
However, its mild flavor comes at a cost – namely, its low-fat content. Omega-3 fatty acids, which are abundant in fish like salmon, contribute to both health benefits and rich flavor. Tilapia’s lack of these fats makes it a lean but somewhat bland choice.
7. Farmed vs. Wild: Neither May Be Ideal
Many people assume that wild fish is always the better option compared to farmed fish. While this is often true for species like salmon, tilapia is a different story.
Wild tilapia are freshwater fish, meaning they live in lakes, rivers, and canals – many of which are polluted. These waters often contain runoff from lawns, sewage, and industrial waste, all of which get absorbed into the fish’s body.
Farmed tilapia, on the other hand, is often raised in overcrowded conditions and may be exposed to antibiotics and lower-quality feed. In other words, whether wild or farmed, tilapia isn’t necessarily the cleanest fish you can eat.
8. Wild Tilapia Eat More Than Just Algae
While farmed tilapia are often fed cheap, unnatural diets, wild tilapia survive mostly on algae and aquatic plants. That might sound better – until you realize that these plants often grow in water contaminated with fertilizers, pesticides, and pollutants.
If a fish’s diet affects its overall quality (which it does), then tilapia’s eating habits – whether wild or farmed – don’t do it many favors.
9. It’s Often Sold Skinless for a Reason
If you’ve ever bought tilapia, you may have noticed that it’s almost always sold as a skinless fillet. That’s because tilapia skin isn’t particularly appetizing, and removing it makes the fish look cleaner and more appealing.
Another reason? Selling skinless fillets means you can’t easily tell whether the fish was farmed or wild, since the color and texture of the skin can give clues about its origin.
10. Tilapia Is One of the Most Requested Fish in Seafood Markets
Despite its controversies, tilapia remains one of the most requested fish in seafood markets. Many consumers, especially those who don’t eat seafood often, prefer it for its mild taste, affordability, and easy preparation.
Fishmongers often hear the same request: “I want a fish that doesn’t taste fishy.” Tilapia fits the bill perfectly, which is why it continues to be a best-seller despite all its drawbacks.
11. If You Want Clean Seafood, There Are Better Choices
While tilapia has its benefits – namely affordability and protein content – it’s far from the best choice for clean eating. With concerns about its diet, farming conditions, and overall nutritional value, other fish like wild-caught salmon, cod, or even sardines may be a better option.
If you’re going to eat tilapia, it’s worth researching where it comes from. Tilapia from certain regions may be cleaner and better farmed than others. If possible, opt for tilapia raised in higher-standard environments rather than the cheapest available option.
Should You Eat Tilapia?
Tilapia isn’t the worst thing you could eat, but it’s not exactly a superfood either. It’s an economical, high-protein fish that’s easy to cook and eat – but it also comes with concerns about farming conditions, diet, and overall quality.
If you’re looking for a cheap, mild-tasting seafood option, tilapia does the job. But if you’re aiming for the cleanest, healthiest seafood, there are much better choices available.
