NFR-Project "RedSlip" aims to reduce slipping mortality by improving our understanding of how the purse seine performs and how the fish behave in, and interact with, the net during the capture process. Previous research has shown that slipping mortality is related to crowding density and duration. This project will investigate whether the stresses associated with capture (including crowding, oxygen starvation and physical injury) can induce changes in the fish behaviour that may be interpreted as warning signals, before the fish are fatally harmed. In addition to understanding how the fish interact with the seine, RedSlip will investigate whether understanding gear performance and being able to predict seine volume during hauling could be used to develop safe release thresholds in purse seine fisheries.
Acoustic and video-based techniques will be used to monitor school structure, crowding densities and gear performance. The experiments will be carried out in net pens and in commercial fisheries, allowing us to relate the information gathered from the laboratory to real commercial fisheries. RedSlip will work in collaboration with colleagues from the fishing industry and international research community to integrate of our knowledge from this project into practical advice on the effective management and regulation of slipping in purse seine fisheries.
Mackerel (Scomber scombrus) will be used as the study species. This species has been shown to be highly sensitive to crowding in the purse seine and supports valuable fisheries in Norway. This project is expected to provide knowledge to enable the safe release of unwanted catches in mackerel fisheries, as well as the development of gear and catch monitoring techniques that will allow more efficient and sustainable purse seine fisheries in the future.
