Can biotic resistance explain the small geographic range of non-native croaking gourami Trichopsis vittata (Cuvier, 1831) in Florida, USA?

November 4, 2019

In this report, we evaluate this hypothesis for croaking gourami Trichopsis vittata, a non-native species that has established a reproducing population, but has not successfully spread beyond its very small (5 km2) range. We suspected the inability of T. vittata to colonize new habitats may be due to biotic resistance by the native eastern mosquitofish Gambusia holbrooki.
