Channa argus is a carrier of non-native parasites and other pathogens (including
myxosporidians, cestodes, trematodes, nematodes, acanthocephalans, and copepods) that could potentially have a significant environmental impact on Great Lakes fauna.

Working with researchers in Japan, the United States Fish and Wildlife Service (USFWS) identified nematodes observed in Channa argus captured from the Potomac River as eustrongylides, native to United States waters; these are typically carried by the killifish the snakehead feeds on.

A disease of snakeheads that has received broad attention is epizootic ulcerative syndrome (EUS), which causes high mortality in these fishes. EUS involves several pathogens, including motile aeromonad bacteria. Only genus known to be affected in US is Cyprinus, but there have been no studies undertaken to examine transfer of parasites or diseases to native North American fishes.

Channa argus is susceptible to infection from a Mycobacterium isoplate. While the pathogenicity in other fishes and the zoonotic potential of this isolate are unknown, mycobacteriosis has potentially serious implications if introduced into the Great Lakes.
