Background information and definitions

Reducing the duration of time that fishing gear is in the water (‘soak time’) may reduce the risk of entanglements and unwanted catch (‘bycatch’) of marine and freshwater mammals. This may include reducing the amount of time that gear is used for active fishing, as well as avoiding leaving static gear in place when not being fished, e.g. to store gear or reserve a fishing patch.

Key messages

We found no studies that evaluated the effects of reducing the duration of time fishing gear is in the water on marine and freshwater mammal populations.

‘We found no studies’ means that we have not yet found any studies that have directly evaluated 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.
