When it comes to seafood, most people focus on the meat and neglect other parts. Little do they know that some of these overlooked parts of fish are edible as well! We often discard scales without giving them a second thought, but have you ever wondered whether or not they can be consumed?
This is where things get interesting – the answer isn’t as straightforward as a simple yes or no. Some cultures consume fish scales regularly, while others would cringe at the mere idea of it. The decision whether or not to eat fish scales ultimately depends on personal preference, but there are nutritional benefits to consider as well.
“Fish scales are rich in calcium – which makes up 97% of its composition – and collagen, a protein essential for healthy skin and hair. So if you decide to give fish scales a try, you’ll be getting more than just a unique culinary experience.”
Still, consuming fish scales may come with some risks. You must take care not to swallow small bones along with the scales, and properly clean the scales to avoid any harmful bacteria or parasites. It’s also important to note that not all fish scales are safe to eat – certain species have thick, tough scales that cannot be digested, such as those of sharks or swordfish.
In this article, we’ll explore everything you need to know about eating fish scales: from nutritional value and safety concerns to cultural traditions and cooking methods. By the end, you might just want to give fish scales a chance and add them to your next meal!

The Nutritional Benefits of Eating Fish Scales
When it comes to eating seafood, people often focus on the fish meat and disregard other parts such as the scales. But are fish scales edible? The answer is yes, and not only can you eat them, but they also offer some nutritional benefits that make them worth considering.
Rich in Collagen and Protein
Collagen is a type of protein that plays a vital role in maintaining healthy skin, hair, nails, and joints. It also promotes overall wellbeing by improving gut health, boosting metabolism, and reducing inflammation in the body.
Fish scales are an excellent source of collagen, which makes them a valuable addition to any diet. According to studies, consuming collagen-rich foods can help improve skin elasticity, reduce wrinkles, and enhance joint health (1).
Besides collagen, fish scales are also a good source of protein, with about 85 grams of protein for every 100 grams of fish scales. This is significant since protein is essential for building and repairing tissues, promoting muscle growth, and regulating metabolic processes in the body.
Source of Essential Minerals
In addition to being rich in collagen and protein, fish scales also contain various essential minerals that our bodies need to function correctly. Some of these minerals include:
- Calcium: Fish scales are among the best sources of calcium, a mineral that is crucial for strong bones, nerve function, and blood clotting (2).
- Phosphorus: Like calcium, phosphorus is critical for maintaining healthy bones and teeth, but it also plays a role in supporting kidney function and managing energy levels in the body (3).
- Potassium: This mineral helps regulate fluid balance in the body, supports heart health, and may reduce the risk of high blood pressure (4).
Incorporating fish scales into your diet can help boost your intake of these essential minerals. For instance, a 100-gram serving of fish scales contains up to 500 milligrams of calcium, making it an excellent alternative source for those who are lactose intolerant or vegan.
“Fish scales have long been used in traditional medicine to promote overall wellbeing due to their nutritional profile.”
While eating fish scales may seem unusual at first, they offer a range of benefits that make them worth considering as part of a well-balanced diet. Additionally, incorporating whole-food options such as fish scales boosts your nutrient intake and serves as a sustainable way to minimize food waste.

Ways to Cook and Eat Fish Scales
Fried Crispy Fish Scales
Yes, you can eat fish scales. And if you are looking for a way to consume the scales of different fishes, frying them until crispy is a great option to start with.
To prepare this dish, first, clean the scales by removing any dirt or impurities from them. Rinse with water and pat dry. You may leave them whole or cut them into smaller pieces according to your preference.
Next, mix some all-purpose flour, salt, pepper, and other seasonings like paprika, garlic powder, or onion powder in a shallow bowl. Coat each scale with the flour mixture evenly on both sides.
Add oil to a pan and heat it over medium-high heat. Once the oil is hot, add the coated scales and fry them until they turn golden brown and crisp.
“Fried fish cooked slowly until its skin is unbelievably crisp and crackly – has been truly galvanizing.” -John Willoughby
Grilled Fish Scales
If you prefer a healthier option, grilling fish scales might be more suitable for you. It requires minimal ingredients and less oil, making it a low-calorie option packed with nutrients.
To make grilled fish scales, preheat the grill to high heat. Clean and rinse the scales and season them simply with salt, pepper, and some lemon juice. Let them marinate for 15 minutes or so before placing them on the grill.
Place your seasoned and marinated scales onto the preheated grill grid and let cook for about 5 minutes on each side. When done, remove from the grill carefully and enjoy with vegetables on the side.
“Fish is one of the staples of a healthy diet, and grilling fish has so many benefits – it’s fast, easy, and convenient.” -Nathan Lyon
As strange as it may sound to some people, fish scales are edible, and they can be incorporated into our diets if desired. Whether you choose to fry or grill them, adding some flavor and seasonings will enhance their taste and texture.
Remember that not all fish scales are safe to eat, depending on the species, habitat, and methods used in obtaining them. Therefore, always consult trusted sources for information and advice before trying any new type of food product.
Are There Any Health Risks Associated with Eating Fish Scales?
Fish scales are often removed before cooking and consuming fish, but there are cultures that include them as part of their traditional cuisine. While fish scales can provide additional texture and flavor to dishes, there are certain health risks associated with consuming them.
Potential Heavy Metal Contamination
One of the major concerns with eating fish scales is potential heavy metal contamination. Fish stores heavy metals such as mercury in its body tissues, including its scales. According to a study published in the Journal of Food Science and Technology, consuming fish scales from contaminated waters can put individuals at risk for increased levels of toxic heavy metals such as lead and cadmium in their bodies. Consuming high levels of these heavy metals over time has been linked with various negative effects on health.
“The repeated ingestion of food containing significant amounts of contaminants may produce adverse effects particularly when this concentration exceeds safety thresholds.” -Tiziana Cappello, et al. (Journal of Food Science and Technology)
Allergic Reactions
Another possible health risk associated with consuming fish scales is allergic reactions. Some people may have an innate allergic response to fish scales, similar to how some react to shellfish or nuts. Skin rashes, itching, swelling or even life-threatening anaphylaxis are all possible symptoms of a fish allergy. Before consuming any type of fish scale or dish that includes it, it’s important to speak with a physician if you’ve experienced any allergic reactions in the past.
“Fish allergies are more common than previously thought and can cause severe reactions.”-Robert J. Haderer Jr., MD, FAAP (American Academy of Pediatrics)
Choking Hazard
Eating fish scales can also pose a choking hazard. Scales are thin and small and may be difficult to swallow, especially if the piece of fish is large or cooked improperly. Children and individuals with dental problems should be extra careful when consuming fish that contains scales.
“To reduce risk of choking, food should not include hard-to-chew foods such as very tough meats, hard candies, gum, raw carrots, popcorn.” -American Academy of Pediatrics
Difficulty in Digestion
Scales from certain types of fish can also be difficult to digest properly. Ingesting indigestible substances can lead to gastrointestinal discomfort such as bloating and stomach pain. While digestion issues aren’t usually considered serious health risks, they can put a temporary damper on your day.
While eating fish scales isn’t recommended for everyone due to potential health risks, it’s ultimately up to an individual whether to incorporate them into their diet. Individuals who wish to try consuming fish scales should consult with their physicians first, especially those with pre-existing conditions or allergies.
The Culinary Traditions of Eating Fish Scales Around the World
Japanese Fish Scale Dish
In Japan, a traditional dish called Tazukuri is prepared using small-fish dried with their scales still intact. The idea behind keeping the scales is that they actually add to the flavor of the finished product. These tiny fish are then sautéed in either soy sauce or sugar until slightly caramelized and eaten as a snack or appetizer.
Fugu Hire-zake is another Japanese cuisine where fish scales have been traditionally used for flavoring. A poisonous pufferfish tail is grilled until charred and served inside hot sake along with the fish’s scales. Scales give this beverage-from-hell a unique and earthy flavor without overpowering the taste buds.
Peruvian Escabeche de Pescado
This hearty stew made from poached fish, potatoes, onions, and spices like cumin and paprika is popular all over South America. In Peru specifically, it uses pan-fried sea bass, tuna, or mackerel that are cooked with the scales left on but only after they’ve been scrubbed clean. Chefs claim that cooking the fish with scales helps retain moisture and allows the flesh to cook evenly. After simmering the mixture with vinegar, lime juice, and chili pepper, the scales soften enough to be easily consumed.
Chinese Fish Scale Soup
The Chinese too make a soup using fish scales that supposedly has numerous health benefits such as strengthening bones and improving skin conditions. The soup preparation begins by boiling finely chopped ginger and garlic followed by adding fish scales, vegetables, and chicken broth. The flavorful concoction must simmer at low heat for several hours so as to get the right texture and taste before servings.
Can You Eat Fish Scales?
Fish scales are edible and safe to eat, although their texture may seem unappealing. Certain cultures around the world have embraced the use of fish scales in traditional dishes or as a nutritional supplement.
- In addition to adding flavor, fish scales have health benefits especially for people with arthritis since they’re packed with collagen — an essential ingredient that contributes to bone health.
- Although traditionally not consumed, large fish like salmon and tuna contain larger scales that can be carefully scraped off, scaled, and grilled to crispy perfection. These crunchy delicacies can add texture to your meal or snack.
“Fish scale consumption might sound strange but many communities have used them to some degree when prepared correctly.” – Dr. Alex Jimenez, a chiropractor who specializes in nutrition and wellness.
The bottom line is, while fish scales may not appeal to everyone’s palate, it’s culturally specific tradition that has been consistent throughout history. So next time you come across a recipe involving scales, don’t shy away from trying it because in specific parts of the world it’s considered a culinary delight!
Fish Scales in Beauty Products: Myth or Reality?
As consumers become more conscious about their beauty products, natural ingredients have gained popularity. It may surprise you to know that fish scales are now being used in various beauty products. Fish scales contain collagen, which is known for its anti-aging and skin-repairing properties.
Collagen-Infused Face Masks
The use of collagen-infused face masks has increased in recent years, with many brands incorporating fish scale extracts into their formulations. These masks claim to boost collagen production, leading to plumper, smoother, and more youthful-looking skin.
“Collagen is essential for maintaining the elasticity of our skin. As we age, our bodies produce less collagen, leading to wrinkles and sagging. Incorporating collagen-rich ingredients like fish scales can help support healthy skin aging,” says Dr. Rachel Nazarian from Schweiger Dermatology Group.
Fish scales are a rich source of marine collagen, unlike other animal sources such as cows and pigs. Marine collagen is considered superior because it has smaller molecules that penetrate deeper into the skin, resulting in better absorption and efficacy.
Shampoos and Conditioners with Fish Scale Extracts
Fish scales also have benefits for hair care. Some shampoos and conditioners contain fish scale extract to strengthen and repair damaged hair. The collagen in fish scales helps increase hair elasticity, improve texture and shine, and reduce breakage and split ends.
“Fish scales contain amino acids, including glycine and proline, which make up a significant portion of collagen. These amino acids play a vital role in promoting scalp health and improving hair growth,” adds Dr. Zeichner, a board-certified dermatologist at Mount Sinai Hospital.
Some studies have shown that topical application of fish collagen can stimulate hair growth and prevent hair loss by increasing dermal papilla cell proliferation, which is necessary for the initiation and maintenance of hair growth.
Body Creams and Lotions with Fish Scale Collagen
Fish scales are not only beneficial for skin and hair care but also body care. Body creams and lotions containing fish scale collagen can help moisturize and firm up the skin, leading to smoother and softer texture. The natural fatty acids present in fish scales also provide hydration to the skin without leaving a greasy residue.
“Fish collagen has been found to possess excellent moisturizing properties due to its high water absorption capacity and ability to retain moisture,” says Dr. Anna Guanche of Bella Skin Institute.
Moreover, many beauty experts believe that fish scale collagen may be more sustainable than other sources because it utilizes waste products from the fishing industry that would otherwise be discarded as trash.
Fish scales are no longer just an ingredient for sushi! It may sound strange, but incorporating fish scale extracts into beauty products has proved to be advantageous. Whether you’re looking to improve the quality of your skin, hair or overall appearance, using these products with marine collagen might work wonders.
