Jordan, Evermann, and Clark (1930) divide these fishes into the four families: Cybiidae, Katsuwonidae, Scombridae, and Thunnidae, but
taxonomists later classified them all into a single family, the Scombridae. The
World Wildlife Fund and the
Zoological Society of London jointly issued their "Living Blue Planet Report" on 16 September 2015 which states that a dramatic fall of 74% occurred in worldwide stocks of scombridae fish between 1970 and 2010, and the global overall "population sizes of mammals, birds, reptiles, amphibians and fish fell by half on average in just 40 years".
