Abalone is primarily used as a luxury seafood, prized across East Asian, Mediterranean, and coastal cuisines for its sweet, buttery flavor and firm texture. Beyond the plate, its iridescent shell has long been used in jewelry and decorative inlays, and more recently, researchers have been investigating its potential bioactive compounds. Here’s a closer look at each of these uses.
A Prized Ingredient in Global Cuisines
Abalone’s reputation as a delicacy centers on its unique taste and texture, often described as a cross between scallop and squid but with a richness all its own. How it’s prepared varies widely by region. In Japanese and Korean cuisine, it’s commonly sliced thin and eaten raw as sashimi, served with soy sauce, wasabi, or ponzu. In Cantonese cooking, braised abalone in oyster sauce is a classic dish reserved for banquets, weddings, and Lunar New Year celebrations. The abalone is slowly simmered with ginger, garlic, and Shaoxing wine until tender, then served alongside greens and rice.
Grilling with butter is another popular preparation, especially in coastal California and parts of Australia. Dried abalone, meanwhile, is a staple in traditional Chinese cooking. The drying process concentrates the flavor and creates a chewy, intensely savory ingredient that gets rehydrated in soups and braises. Canned abalone is widely available in Asian grocery stores and serves as a more affordable entry point, though fresh and live abalone command the highest prices. Depending on the species and preparation, a single dish featuring abalone at a fine restaurant can easily cost over $100.
Nutritional Profile
Abalone is a lean, protein-dense seafood. Per 100 grams of raw abalone, you get roughly 17 grams of protein alongside meaningful amounts of several micronutrients. It’s particularly rich in vitamin B12, delivering about 15 micrograms per serving, which is several times the daily recommended intake for adults. Selenium comes in at around 22 micrograms, covering a significant portion of daily needs, while magnesium sits at about 65 milligrams.
One thing to note: abalone contains about 139 milligrams of cholesterol per 100-gram serving, which is moderate compared to other shellfish like shrimp. It’s low in fat overall, making it a nutrient-dense choice if you can get your hands on it.
Shell Uses in Jewelry and Craft
The inside of an abalone shell is lined with nacre, the same iridescent material found in pearls. This “mother of pearl” layer shimmers with blues, greens, and purples depending on the angle of light, making abalone shells one of the most visually striking natural materials available. They’ve been used for centuries in jewelry, buttons, watch faces, and decorative inlays on furniture, musical instruments, and knife handles. Guitar makers, in particular, frequently use abalone shell for fretboard inlays and rosettes around the sound hole.
Indigenous peoples across the Pacific Coast of North America, New Zealand, and parts of Southern Africa have used abalone shells in ceremonial objects, currency, and adornment for thousands of years. In many of these cultures, the shells still hold deep spiritual significance.
Bioactive Compounds Under Study
Researchers have begun isolating specific compounds from abalone tissue, particularly from the viscera (the internal organs typically discarded during food preparation). Lab studies have found that certain peptides extracted from abalone viscera act as potent antioxidants, protecting cells from oxidative damage. In one study, synthesized peptides from abalone significantly increased the survival of liver cells exposed to harmful levels of hydrogen peroxide, while also boosting the activity of the cells’ own protective enzymes.
These findings are still in the early, laboratory stage. No abalone-derived supplements have been approved for medical use. But the research reflects a broader trend of looking at marine organisms as sources of bioactive molecules, and abalone’s long history in traditional Chinese medicine as a tonic for the eyes, liver, and kidneys has helped fuel scientific interest.
Farming Has Overtaken Wild Harvest
If you’re eating abalone today, it almost certainly came from a farm. Global abalone aquaculture has grown from virtually nothing in the 1970s to over 243,000 metric tons in 2020/21. Wild fisheries, by contrast, have collapsed in the opposite direction: from about 20,000 metric tons in the 1970s to roughly 5,850 metric tons over the same period. China, South Africa, Australia, and South Korea are the leading producers, with China dominating the market by a wide margin.
This shift matters because wild abalone populations are in serious trouble. Several species are now critically endangered, including white abalone, black abalone, and red abalone along the U.S. Pacific coast. California shut down its recreational red abalone fishery entirely in 2018. South Africa’s perlemoen abalone is listed as endangered, with illegal poaching so severe that the legal managed fishery has been described as “almost reduced to a footnote.” Globally, an estimated 7,000 metric tons of abalone are harvested illegally each year, driven by the high prices the meat commands on the black market.
Farm-raised abalone helps meet demand without further pressuring wild stocks, and most abalone sold in restaurants and markets today carries that aquaculture origin. If sustainability matters to you, checking whether your abalone is farmed is the simplest step you can take.
