Threadfin — the fourfinger threadfin Eleutheronema tetradactylum, known across the region as ikan kurau — is a silvery, blunt-headed coastal fish of the Indo-Pacific, named for the loose, thread-like lower rays of its pectoral fins. Its firm, snow-white, low-fat flesh, sweet and almost boneless in the fillet, makes it one of the most esteemed table fishes of Chinese and Southeast Asian cooking, prized above all steamed whole and served as a first fish for infants and convalescents.
