What is Managatsuo (Silver Pomfret)?

Managatsuo ( Pampus argenteus ), also called Silver Pomfret or Bigeye Pomfret, belongs to the family Stromateidae. The name "managatsuo" comes from the Edo period, when fresh bonito was hard to get in Kyoto, so this fish was used as a substitute and called "manakatsuo". Over time, the kanji changed to "真魚鰹" or "真名鰹".

Managatsuo is a wild fish, rarely farmed, and is mainly caught by coastal fisheries using trawl nets, set nets, and gillnets. Because the catch is limited, it is considered a luxury fish in Japan. ^[1]

Cultural and Seasonal Significance

In the Seto Inland Sea, managatsuo migrates to the coast for spawning from late June to early September. The "summer managatsuo" before spawning is considered the tastiest, as it is full of nutrients. The main fishing season is from early summer to autumn. ^[2]

There is even a saying: "No salmon in the west, no managatsuo in the east," showing how much this fish is loved in western Japan. In Kyoto cuisine, it was used for namasu (vinegared dishes) and is mentioned in old cookbooks. Along the Seto Inland Sea, it is a highlight of summer festivals and special occasions.

Habitat and Distribution

Managatsuo is found from the southern East China Sea to the South China Sea, Indian Ocean, Yellow Sea, and Persian Gulf, living mainly on sandy or muddy continental shelves at depths of around 200 meters. In Japan, it is distributed from central Honshu southwards, including the Ariake Sea, Seto Inland Sea, and the western coast of Kyushu. ^[3]

During winter and spring, managatsuo moves to deeper waters, returning to coastal shallows in summer to spawn. In the Seto Inland Sea, spawning takes place from late June to early September. ^[4]

Managatsuo in Japanese Cuisine

Managatsuo is a luxury white fish enjoyed in many ways, depending on its freshness and size. Here are some of the most popular ways to prepare and enjoy it in Japan:

• Sashimi: Large or super-fresh managatsuo (over 3 kg) is served as thinly sliced sashimi. The texture is pleasantly chewy, and the flavor is mild with a hint of sweetness. The scales and belly bones are carefully removed, and the skin is peeled before slicing. Learn more about sashimi
• Grilled: Popular methods include Saikyo miso-marinated, yuzu-miso grilled, and Yuanyaki (marinated in soy sauce, mirin, and yuzu juice). Smaller fish are often simply salted and grilled, or made into dried fish for a more intense flavor. Try a homemade teriyaki sauce
• Fried: For karaage, the fish is cut into bite-sized pieces, seasoned with sake, salt, pepper, and garlic, coated in potato starch, and deep-fried until crispy. It is also delicious as tempura, with the belly bones removed and a light batter for a fluffy finish. How to make karaage Tempura basics
• Simmered: Managatsuo is simmered in a mixture of soy sauce, sugar, mirin, and sake, often with a drop lid to keep the fish moist. For ankake, vegetables or mushrooms are added to the simmering liquid, and the sauce is thickened with potato starch. What is miso? What is mirin?
• Sushi and Namasu: In Kyoto cuisine, "managatsuo namasu" is a classic dish, with thin slices of the fish marinated in vinegar. In some sushi restaurants along the Seto Inland Sea, you can find managatsuo nigiri during the summer season. Kaiten-zushi: Conveyor belt sushi

Appearance and Taste

Managatsuo usually measures 30–60 cm in length, with a flat, high body that looks almost diamond-shaped from the side. The color is a metallic silver-gray with a bluish tint, and the skin is thin and easily loses its scales. The fins are translucent, and the tail fin fans out elegantly.

The flesh is fine-grained, smooth, and moderately fatty. When cooked, it flakes apart easily and has a subtle sweetness. The flavor is mild, with little fishiness, making it a great match for sake or white wine. When deep-fried, the outside becomes crispy while the inside stays soft and moist, offering a delightful contrast in texture. What is sake?

Compared to other fish, managatsuo is softer and more elastic than sea bream, and lighter and sweeter than amberjack. It is less firm than sea bream and has a unique, slightly chewy texture.

Resource Management and Fisheries

Because managatsuo is not caught in large quantities, resource management and catch regulations are important for stable supply. Measures such as setting fishing seasons and size limits are being implemented in cooperation with local fishers and government agencies. For more details, see the official reports from the Japanese Fisheries Agency. ^[5]
