Chanidae (milkfish, salmon-herring; subclass Actinopterygii, order Gonorynchiformes) A monospecific family (Chanos chanos), comprising a fish whose streamlined body and long, deeply forked tail fin give it a graceful appearance. Because of its fairly small, toothless mouth, the single dorsal fin, and the bright, silvery colour, it is sometimes also known as the giant herring. Milkfish often form large schools, swimming near the surface. Along the shores of many tropical countries it is an important source of protein for humans. The young are caught in large numbers, placed in fish ponds, and kept until they are of marketable size. It is found in the tropical waters of the Indo-Pacific and S. American regions, where it can grow to at least 1 m in length.
