A controlled study comparing six native fish species with the introduced (and invasive) eastern mosquitofish (Gambusia holbrooki) on consuming larvae of the common banded mosquito (Culex annulirostris) in Brisbane found that the empire gudgeon was as efficient at eating mosquito larvae as the eastern mosquitofish and is a good candidate for ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
Western carp gudgeon are purportedly the most common of the carp gudgeons. However, recent genetic research suggests that the carp gudgeons are a cryptic species complex composed of at least four species and many hybrids; their taxonomy is extremely complicated, unresolved, and not accurately reflected by current scientific and common names.
Kessler's gudgeon is a shallow-bodied, silvery fish with a pointed snout that grows to a length of about 12 centimetres (4.7 in) or occasionally 15 centimetres (5.9 in). It has a pair of barbels by the mouth which help it locate food and which are long enough to reach to the far side of the eye. [ 3 ]
