Article Synopsis
- Marine sediments are significant carbon stores, but bottom trawl fisheries disturb seabed habitats, potentially impacting the ocean's carbon dioxide sink.
- Research is concerned that trawling may turn these sediments into a significant source of CO, but there's a lot of uncertainty due to limited understanding of how trawling affects sediment mixing and carbon processes.
- A review protocol will investigate the effects of mobile bottom fishing on carbon processing and storage in sediments by addressing various questions about carbon types, fluxes between benthic and pelagic systems, and the biological and physical controls on this carbon.
Ecosystem effects of bottom trawl fisheries are of major concern. Although it is prohibited to catch fish using electricity in European Union waters, a number of beam trawlers obtained a derogation and switched to pulse trawling to explore the potential to reduce impacts. Here we analyse whether using electrical rather than mechanical stimulation results in an overall reduction in physical disturbance of the seafloor in the beam-trawl fishery for sole Solea solea.
