The signature freshwater fish of Danjiangkou Reservoir, a silver-finned predatory species whose dense musculature and high amino acid content set it apart from ordinary river fish. Pan-frying over sustained moderate heat is the deliberate technique of choice: the culter's many fine intramuscular bones become edible—crisp and crumbling—when held against a hot pan surface long enough, eliminating what would otherwise be a constant navigational hazard for diners.
The topmouth culter (翘嘴红鲌) is a native predatory species of the Yangtze and Han rivers. Fishermen of Junzhou (present-day Danjiangkou) historically called it 'the great white fish.' A widely circulated local legend holds that the Ming dynasty Yongle Emperor, on a visit to Wudang Mountain, tasted the fish and designated Junzhou's white culter as a tribute species—though this account rests on oral tradition without corroborating historical records and should be treated as lore. The construction of Danjiangkou Dam created a vast deep-water reservoir whose cold, clear, mineral-rich environment proved especially favorable for the culter's development. In 2008, Danjiangkou topmouth culter became China's first aquatic species to receive geographical indication certification for live fish, confirmed by the State Administration for Quality Supervision. In December 2020, pan-fried Danjiangkou culter was codified as one of the inaugural 21 Chu cuisine standards.
The skin arrives crackling and faintly blistered, pulling away from the flesh with a papery crunch. Beneath it the flesh is pristine white, fine-grained, and clean-tasting—a sweetness specific to cold, clear reservoir water that muddy river fish lack entirely. Most of the small intramuscular bones have crisped to near-invisibility; those that remain dissolve under gentle molar pressure. The wild mountain pepper and garlic sauce applied at the finish adds warmth and aromatic sharpness without masking the fish's own mineral character.
The culter's many fine intramuscular bones become edible through the combined action of low temperature and prolonged contact with the hot pan surface. At sustained temperatures of approximately 160–170°C, the collagen binding the tiny bone matrix gradually denatures and loses structural integrity; the calcium phosphate framework, already thin in small intramuscular bones, becomes brittle enough to crumble under molar pressure. The scoring cuts spaced 2 cm apart expose the maximum surface area of these bones to direct heat, accelerating the process. The marinade's salt draws free moisture from the skin layer via osmosis, producing a drier surface that frys to a crisper finish. High heat is used briefly at the start to trigger Maillard browning on the skin, then reduced so that heat penetrates toward the thicker dorsal musculature without overcooking the outer flesh.
Variations
The same fish is presented as whole steamed culter (清蒸翘嘴鲌) for diners who prefer unadulterated freshness—no marinade, only ginger, scallion, and the fish's own juices. A winter-dried version (风干翘嘴白) is produced by air-drying the fish for several days in cold weather, concentrating its flavor and extending shelf life for months. At the full-fish banquet (全鱼宴) that is the centerpiece of Danjiangkou restaurant culture, the same fish may appear simultaneously in four preparations.

How it's made
7 steps · 20 min
- 110 min
Scale, gut, and remove gills from the fish; rinse and pat completely dry. Score both sides with deep diagonal cuts spaced 2 cm apart, cutting down to but not through the backbone to expose the intramuscular bones to heat.
Watch outScore deep to the backbone at 2 cm intervals — this exposes the fine bones to the pan heat so they crisp brittle enough to eat.
- 260 min
Season generously inside the cavity and across the scored surfaces with salt, cooking wine, crushed Sichuan peppercorns, ginger slices, and scallion knots; marinate at room temperature for 1 hour or refrigerate overnight for deeper flavor.
- 35 min
Remove ginger and scallion from the fish; use kitchen paper to pat the skin surface completely dry; dust both sides lightly with cornstarch and shake off any excess.
- 46 min
Heat a cast-iron or heavy-bottomed pan over medium-high heat; add oil; when the surface shimmers, lay fish in the pan and press down firmly with a spatula for 30 seconds to prevent curling; fry undisturbed for 4 minutes until the skin releases naturally from the pan.
Watch outPress the fish flat thirty seconds, then leave it untouched until the skin releases on its own — move it early and the skin sticks and tears.
- 56 min
Flip carefully; reduce heat to medium-low; fry the second side for 4–5 minutes until deeply golden, with the scored cuts visibly crisped and the fish cooked through when tested with a thin skewer.
Watch outSecond side goes deep golden with the scored cuts visibly crisped — that's the sign the little bones have gone brittle through.
- 63 min
Push fish to one side; in the cleared pan space, fry minced garlic, fresh chili rings, and wild mountain pepper in the residual oil for 30 seconds; splash in oyster sauce and 2 tablespoons of water and let sizzle for 20 seconds.
- 72 min
Spoon aromatics and sauce over the fish; transfer to a serving plate; scatter sliced scallion on top and serve immediately while the skin is still crisp.
