About
A phono-semantic compound, 鳔 (traditional: 鰾) uses the fish radical 鱼 to classify it within aquatic anatomy. Its right component, 票, provides the pronunciation "biao". Etymologically, the character refers to a fish's swim bladder, the internal organ that regulates buoyancy. In culinary and commercial use, it also denotes the dried organ, processed for food or adhesive production.
