The data includes six newly mapped families: Engraulidae, Zenarchopteridae, Ambassidae, Butidae, Oxudercidae, and Osphronemidae. In addition, thirty-three synonym names have been validated. Cyprinidae (4 species) and Ambassidae (3 species) are the families with the largest species. 87.80% euryhaline species, 12.20% freshwater species, and 63.41% migratory species (amphidromous, anadromous, catadromous, oceanodromous, and potamodromous).
