Background information and definitions

If birds are attracted to the fish caught in gillnets then removing the nets more quickly may reduce their attractiveness to birds and so reduce bycatch.

Key messages

We found no evidence for the effects on seabird bycatch rates of reducing gill net deployment time.

'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.

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.
