The International standard statistical classification of aquatic animals and plants, abbreviated as ISSCAAP, is a nomenclature developed by the United Nations (UN) Food and Agriculture Organization (FAO).
For statistical purposes, nominal catches of aquatic animals and plants, taken in inland and marine waters or derived from aquaculture, for all kinds of commercial, industrial and subsistence purposes, are presented at either species, genus or family level in approximately 1250 statistical categories called "species items"; these species are classified in 50 groups of species and 9 divisions in ISSCAAP.
