Background information and definitions
Encouraging native predators could potentially increase predation on the population of invasive gobies, thereby biologically controlling goby populations. For example, a before-and-after field and modelling study, from 1999-2008 in Lake Erie, North America suggested that predator control of round goby Neogobius melanostomus,
by native burbot Lota lota could be effective at controlling population size (Madenjian et al. 2011). Populations of native burbot were reported to have high potential for predatory control of invasive round gobies and computer modelling indicated that in 2007, burbot consumed approximately 61% of round goby standing stock (Madenjian et al. 2011). Although many species consume round goby, no effective and species-specific biocontrol has yet been reported. More work is therefore required.
