Action: Ponto-Caspian gobies: Using a combination of netting and electrofishing
Key messagesRead our guidance on Key messages before continuing
- No evidence was captured on the use of a combination of electrofishing and gill netting to control goby populations.
'No evidence' for an action means we have not yet found any studies that directly and quantitatively tested this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.
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).
