2204 Channa argus Competition Experimental N/A At the present level of co-occurrence, a model predicts only a 3.8% reduction in largemouth bass due to comeptition with northern snakehead. However, as co-occurrence was increased in the model, so did the reduction in largemouth bass by 35% in the set parameters. Mid-Atlantic states, lower Mississippi River basin 32206
2209 Channa argus Competition Anecdotal Field If the abundance of northern snakehead in the Potomac River does not significantly increase, the impacts may be minimal. Mid-Atlantic states, lower Mississippi River basin 29012
6474 Channa argus Competition Anecdotal N/A Due to its voracious predatory nature, wide environmental tolerance, and varied diet, Channa argus has a high potential of outcompeting native species for food resources and altering food-web dynamics. 32166
6475 Channa argus Competition Anecdotal N/A Competition for habitat is only likely to be significant during spawning seasons. 13490
6476 Channa argus Competition Observational Field Immigration of fish species to Turkmenistan from Uzbekistan, which included Channa argus, caused an observed decline in the number of native species. Turkmenistan reservoirs 41949
6589 Channa argus Competition Observational Field Adult Channa argus show significant diet overlap with largemouth bass (Micropterus salmoides), with both consuming a large proportion of fundulids and other centrarchids in the lower Potomac River. Overall, little evidence for potential direct competition between northern snakehead and native predators were found in this study. Potomac River 24962
6590 Channa argus Competition Anecdotal N/A Channa argus are able to tolerate habitats with extremely low dissolved oxygen content which provides a competitive advantage over native species such as pike (Esox sp.) or bass (Micropterus sp.). 42017
