Opah, also known as moonfish, is a fascinating and relatively uncommon fish that has been gaining popularity in culinary circles. Its vibrant colors and unique flavor profile make it a sought-after ingredient for chefs and adventurous home cooks alike. But the question remains: is opah truly “good eating”? This article will explore the flavor, texture, nutritional value, sustainability, and preparation methods of opah to help you decide if this intriguing fish is right for you.
What Makes Opah So Special?
Opah stands out from other fish for several reasons. Its most striking characteristic is its appearance. These fish boast a kaleidoscope of colors, from rosy reds and oranges to silvery blues and greens. This dazzling display comes from their iridescent scales. The name “moonfish” comes from its large, round shape, which further adds to its distinctive appearance.
But the appeal of opah goes far beyond aesthetics. Its unique flesh sets it apart. Unlike many fish that have a single type of muscle, opah contains different types of meat, each with its own color, texture, and flavor. This variety contributes to the fish’s overall complexity and makes it a delightful culinary experience.
Opah is the only known fully warm-blooded fish. This allows them to thrive in a wider range of ocean temperatures, giving them a unique physiological advantage. This warm-bloodedness may also contribute to the quality of their meat.
A Flavor and Texture Adventure
The flavor of opah is often described as a cross between tuna and swordfish, with a subtle richness and a slightly sweet undertone. Its taste is considered mild and delicate, making it a versatile ingredient that can be used in a variety of dishes. The flavor profile varies depending on which part of the fish you are eating.
The texture of opah is equally intriguing. Due to its diverse muscle composition, you can experience everything from firm and meaty to tender and flaky within a single cut. Closer to the center of the fish, the meat tends to be more dense and steak-like. Nearer the edges, it becomes softer and more flaky.
The “loin” section of the opah is often considered the most desirable cut. It offers a firm, meaty texture and a rich flavor that is perfect for grilling or searing. The “cheek” meat is exceptionally tender and sweet and is a delicacy in some cultures.
Exploring Opah’s Diverse Muscle Types
The diverse muscle types of opah contribute significantly to its appeal. Each muscle section has distinct color and texture. The four primary muscle types are:
- Loin: The largest section, typically pink or orange, with a firm, steak-like texture and mild flavor.
- Cheek: A small, delicate portion with a light pink color and a tender, sweet flavor.
- Belly: A fattier section, often reddish in color, with a rich flavor and a soft texture.
- Collar: Located near the head, it’s typically dark red and flavorful, with a slightly tougher texture.
These different textures and tastes create a complex and enjoyable eating experience.
Comparing Opah to Other Popular Fish
Opah’s flavor and texture profile is different from other popular fish like salmon, cod, or halibut. Salmon is known for its oily richness, while cod is mild and flaky. Halibut is firm and lean. Opah offers a unique blend of characteristics, falling somewhere in between these extremes. It boasts a more substantial texture than cod but is less oily than salmon. Its mild, slightly sweet flavor sets it apart from halibut.
This unique combination makes opah a great alternative for those looking to expand their seafood horizons. If you enjoy tuna or swordfish, you will likely appreciate the flavor and texture of opah.
Nutritional Benefits of Opah
Beyond its delightful flavor, opah is also a nutritious choice. It is packed with essential nutrients that contribute to overall health and well-being.
Opah is an excellent source of protein, which is essential for building and repairing tissues in the body. It is also relatively low in calories and fat, making it a healthy option for those watching their weight.
Opah is rich in omega-3 fatty acids. These healthy fats are known for their benefits to heart health, brain function, and reducing inflammation. It also contains important vitamins and minerals, including vitamin B12, selenium, and magnesium.
Omega-3 Fatty Acids: A Key Benefit
Omega-3 fatty acids are a type of polyunsaturated fat that is crucial for various bodily functions. They play a vital role in maintaining heart health by reducing triglyceride levels, lowering blood pressure, and preventing blood clots. Omega-3s also support brain function, improving memory and cognitive performance. Additionally, these fatty acids have anti-inflammatory properties, which can help reduce the risk of chronic diseases like arthritis.
Opah is a good source of both EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), two of the most important types of omega-3 fatty acids. Including opah in your diet can help you meet your daily omega-3 requirements and reap the numerous health benefits associated with these essential fats.
Comparing Opah’s Nutritional Value to Other Fish
When compared to other popular fish, opah holds its own in terms of nutritional value. It offers a similar amount of protein as tuna and salmon but with fewer calories and fat than salmon. While salmon is higher in omega-3 fatty acids, opah still provides a significant dose of these essential fats.
Here’s a brief comparison:
- Opah: High in protein, moderate in omega-3s, lower in calories and fat compared to salmon. Good source of selenium and vitamin B12.
- Salmon: High in protein and omega-3s, higher in calories and fat than opah. Also a good source of vitamin D.
- Tuna: High in protein, moderate in omega-3s. Can be higher in mercury than opah.
- Cod: High in protein, low in fat and calories, but lower in omega-3s compared to opah.
Sustainability Considerations
As consumers become more aware of the environmental impact of their food choices, sustainability is an increasingly important consideration. The good news is that opah is generally considered a sustainable seafood choice.
Opah populations are relatively healthy. They are not currently overfished. Furthermore, opah are typically caught as bycatch in fisheries targeting other species, such as tuna and swordfish. This means that they are not specifically targeted, reducing the potential for overfishing. However, it’s still important to be mindful of the fishing methods used to catch opah and to choose fish from responsible sources.
Choosing Sustainable Opah
When purchasing opah, look for certifications from organizations like the Marine Stewardship Council (MSC) or consult seafood guides from reputable sources like the Monterey Bay Aquarium’s Seafood Watch program. These resources can help you make informed choices and support sustainable fishing practices.
Choosing sustainably caught opah helps protect marine ecosystems and ensures that future generations can enjoy this unique and delicious fish.

What does Opah taste like?
Opah, also known as Moonfish, boasts a unique flavor profile because it’s not just one type of meat, but a combination of several. Generally, the taste is often described as a cross between tuna and swordfish, with a slightly sweet and buttery undertone. The different cuts of meat offer distinct textures and flavors. For example, the loin is firmer and more akin to tuna, while the cheek meat is more tender and flavorful.
The color of Opah meat also indicates the flavor nuances. The darker, reddish-orange meat near the center is richer and more robust, perfect for grilling or searing. The lighter, paler meat around the edges is milder and lends itself well to raw preparations like sushi or sashimi. This diversity in taste and texture makes Opah a versatile and exciting fish to cook with.
Is Opah a sustainable seafood choice?
Opah is generally considered a sustainable seafood option because they are not specifically targeted by fisheries. They are primarily caught as bycatch in longline fisheries targeting tuna and swordfish. The good news is that Opah populations are healthy, and their reproductive rate is relatively high, making them resilient to fishing pressure. Fisheries management practices also play a role, with some areas having stricter regulations to minimize bycatch and protect marine ecosystems.
When purchasing Opah, it’s always a good idea to check the source and look for certifications from organizations like the Marine Stewardship Council (MSC). Choosing Opah from well-managed fisheries helps support sustainable fishing practices and ensures the long-term health of Opah populations. You can also consult seafood guides provided by organizations like the Monterey Bay Aquarium’s Seafood Watch to make informed decisions.
What are the different ways to cook Opah?
Opah’s versatility makes it suitable for a wide range of cooking methods. Its firm texture holds up well to grilling, searing, and baking. Grilling brings out the natural sweetness of the fish, while searing creates a delicious crust and keeps the inside moist. Baking is a gentle method that preserves the delicate flavors. Opah is also fantastic when poached or steamed, especially when paired with aromatic herbs and spices.
Beyond cooked preparations, Opah shines in raw dishes. Its high-quality meat makes it an excellent choice for sushi, sashimi, and ceviche. When serving raw, ensure the fish is fresh and sourced from a reputable supplier. Consider marinating Opah in citrus juices and herbs to create a flavorful ceviche, or simply slice it thinly and serve it with soy sauce and wasabi for a classic sushi experience.
Is Opah high in mercury?
Like many large, predatory fish, Opah can accumulate mercury in its tissues. However, compared to other similar species like swordfish and tuna, Opah generally has lower mercury levels. The amount of mercury in fish can vary depending on factors such as their age, diet, and location. Larger, older fish tend to have higher mercury concentrations than smaller, younger ones.
While Opah can contain mercury, it’s typically safe to consume in moderation as part of a balanced diet. Health organizations generally recommend that pregnant women, nursing mothers, and young children limit their consumption of high-mercury fish. However, for most adults, enjoying Opah occasionally as part of a varied seafood intake poses minimal risk. Checking with a healthcare professional can provide personalized guidance if you have specific concerns.
Where can I buy Opah?
Opah can be found at various seafood retailers, depending on your location. Specialized fish markets are often the best place to find fresh, high-quality Opah. Asian markets and some well-stocked grocery stores with a dedicated seafood counter may also carry it. Ask your fishmonger about the source of the Opah and when it was caught to ensure freshness. If you live in a coastal area, you may also be able to purchase Opah directly from local fishermen.
Online seafood retailers are another option, especially if you don’t have access to a local fish market. When buying online, research the retailer’s reputation and shipping practices to ensure the Opah arrives fresh and properly packaged. Look for online retailers that specialize in sustainably sourced seafood. If you’re unsure, call the retailer and inquire about their sourcing practices and quality control measures before placing your order.
What are the nutritional benefits of eating Opah?
Opah is a nutrient-dense fish that offers numerous health benefits. It’s an excellent source of high-quality protein, which is essential for building and repairing tissues. Opah is also rich in omega-3 fatty acids, particularly EPA and DHA, which are beneficial for heart health, brain function, and reducing inflammation. Additionally, Opah contains several vitamins and minerals, including vitamin D, vitamin B12, selenium, and potassium.
Furthermore, Opah is relatively low in saturated fat and calories, making it a healthy choice for those watching their weight or cholesterol levels. The combination of protein, omega-3 fatty acids, and essential nutrients in Opah contributes to overall well-being. Incorporating Opah into your diet can support cardiovascular health, cognitive function, and a healthy immune system. However, it’s always best to consult a nutritionist or healthcare professional for personalized dietary recommendations.
How should I store Opah after purchasing it?
Proper storage is crucial to maintain the freshness and quality of Opah. Immediately after purchasing, place the fish in a refrigerator at a temperature of 40°F (4°C) or lower. The best way to store it is to wrap it tightly in plastic wrap or place it in a sealed container. Laying the Opah on a bed of ice in the refrigerator can help maintain a consistent cold temperature and extend its shelf life. Make sure any melting ice drains away from the fish to prevent it from becoming waterlogged.
Ideally, Opah should be cooked within one to two days of purchase. If you need to store it for longer, consider freezing it. To freeze Opah, wrap it tightly in freezer-safe plastic wrap, then place it in a freezer bag or container. Label the bag with the date and freeze for up to three months. When you’re ready to use frozen Opah, thaw it in the refrigerator overnight for the best results. Avoid thawing it at room temperature, as this can promote bacterial growth.
