Ponto-Caspian gobies: Using a combination of netting and electrofishing
Overall effectiveness category Awaiting assessment
Number of studies: 0
Background information and definitions
Applying a combination of netting and electrofishing may prove particularly effective in controlling populations of invasive gobies. Studies have shown this to be effective for other fish species. For example, two before-and-after studies in Australia and the UK found that electrofishing and gill netting combined were effective at reducing topmouth gudgeon Pseudorasbora parva populations (Pinto et al. 2005; Copp et al. 2007). Also, a replicated, paired sites study in the USA demonstrated that gill netting and electrofishing reduced or eradicated non-native trout (Oncorhynchus species, Salmo species, and Salvelinus species), and facilitated a partial reversal in the decline in yellow-legged frog Rana muscosa (Knapp et al. 2007).
