Native range. Japan, China, Taiwan, and Vietnam ( East Asia).

Remarks. As native populations of this species occur in several reservoirs, the distribution records presented above include only obvious feral populations (e.g., including many damaged individuals and/or found in exceptionally high abundances in channelised water courses). Historically, this species has been cultivated in fish ponds since the 1940s (Lin, 1949), and non-native individuals may have been able to breed in local fresh waters or interbreed with native populations. Channa maculata differs from Channa argus and their hybrids by having a single stroke in the dorsal head pattern in between the eyes (more separated from the eyes, the larger they become) and smaller blotches on its lateral side (for further details, see Ou et al., 2018).
