Key messagesRead our guidance on Key messages before continuing
- We found no evidence for the effects on seabird bycatch rates of using water cannon when setting longlines.
'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
A water cannon used when longlines are set could unsettle birds and stop them from coming close enough to the boat to attack baits and get hooked.
