The study reveals a decline in tilapia populations linked to competitive interactions with invasive species.
Dietary overlap between tilapia and non-native species like bluegill and juvenile largemouth bass is significant.
Nine invasive species dominate the fish community, with only one native species present in the reservoir.
Collaborative management approaches are recommended to address the impact of invasive predators on local fisheries.
