What is "salangidae"

Icefishes or noodlefishes are a family, the Salangidae, of osmeriform fish, related to the smelts. They are found in freshwater environments in East and Southeast Asia, although a few species are anadromous (e.g., Salangichthys microdon), spending most of their lives in coastal waters, and only visiting fresh water to spawn.
