It has been predicted that Channa argus could substantially modify the ecosystem balance of waters with low diversity and low abundance of native predatory species through top-down mechanisms.

Among the forage fish consumed by Channa argus in the Potomac River, Banded Killifish (Fundulus diaphanus), Bluegill (Lepomis macrochirus), Pumpkinseed (L. gibbosus), and White Perch (Morone americana) were most commonly observed.

Adverse impacts on threatened and endangered species would likely be high. Of all the taxa listed as endangered or threatened in U.S. aquatic habitats, 16 amphibians, 115 fishes, and 5 of the 21 crustaceans (surface dwelling crayfish and shrimp), would be the most likely to be affected. Based on habitat requirements and life history, amphibians and surface-dwelling crustaceans would generally be less likely to be affected by introduced Channa argus than would fishes.
