Discover the 4 unique fish that cannot be successfully farmed artificially, and why their wild-caught nature makes them a delicacy worth seeking out.
Mountain Eel (Cá chình suối)

A delicacy worth the price: Mountain Eel, a wild-caught treat with sweet, firm flesh
Mountain eels (Cá chình suối) are primarily found in fast-flowing mountain streams and creeks, thriving in pristine waters. Due to their specific habitat requirements, attempts to farm them artificially have not been successful. This fish boasts firm, sweet, and flavorful meat that is also highly nutritious. Popular preparations include grilled, braised with bananas and beans, or simmered in a turmeric-infused broth, a dish that highlights the natural sweetness of the eel combined with the distinctive aroma of turmeric.
Anh Vũ Fish (Cá anh vũ)
Anh Vũ fish, also known as “Royal Fish” (“Cá tiến vua”), has a history of being served to royalty. This fish is particular about its habitat, thriving only in clean waters with pebbly bottoms, such as the Đà, Gâm, and Lô rivers. While known for its tender, sweet meat and high nutritional value, farming Anh Vũ fish artificially is challenging due to their exacting habitat requirements. Wild-caught Anh Vũ fish is superior in quality, and grilling or steaming are popular preparation methods that showcase its subtle, exquisite flavor.
Sardines (Cá cơm)
Sardines (Cá cơm) are small, nutrient-rich sea fish, packed with omega-3 fatty acids and calcium. They cannot be farmed artificially, so they are exclusively wild-caught. Sardines have soft, buttery flesh and are highly versatile in the kitchen. They can be fried to a crisp, braised with pepper, or made into a flavorful fish sauce (“mắm cá cơm”). Their rarity and distinctive flavor make wild-caught sardines a prized delicacy, commanding a high market value.
Rice Field Fish (Cá rô đồng)

Rice Field Fish: A Wild Delicacy with a Unique Flavor and High Nutritional Value
Rice Field Fish (Cá rô đồng) is a common freshwater fish in Vietnam, found in rice fields, natural ponds, and canals. Its meat is firm, flavorful, and low in fat, with a delicious aroma. However, farming Rice Field Fish is challenging due to their complex growth habits and the need for a carefully controlled environment. Popular preparations include braising in a clay pot, deep-frying for a crispy treat, or simmering in a bitter herb soup, each method resulting in a distinct and appealing dish.
These fish not only offer exceptional flavor but also provide a wealth of nutrients, making them a worthwhile culinary adventure. While their wild-caught nature makes them less readily available and commands a higher price, it is worth keeping an eye out for them at the market or seafood store. Indulging in these wild-caught delicacies will undoubtedly add a touch of adventure and uniqueness to your dining table, showcasing the very best that nature has to offer.
