A study by the Helmholtz-Zentrum Hereon institute has found that bottom trawling in the North Sea leads to the release of around one million tons of CO2 into the atmosphere annually. The study, published in the journal Biogeosciences, also shows that restrictions on fishing in certain areas could benefit both marine life and carbon storage. The institute suggests that avoiding carbon-rich muddy grounds and using alternative fishing methods could reduce emissions. The study also highlights the need to consider the ecosystem service of carbon storage in the designation of marine protected areas.

Fishing trawls cause significant CO2 emissions as they stir up the carbon bound in the seabed and release it again. It is also clear that they drastically affect ecosystems in the ocean. A new study by the Helmholtz-Zentrum Hereon models the influence of bottom trawls on sedimentary carbon in the North Sea. It also shows that restrictions on fishing in certain areas would benefit life in the ocean and on land.The study is published in the journal Biogeosciences.What would happen if bottom trawling were banned in all currently designated marine protected areas? In the North Sea, trawls cause CO2 emissions on the order of one million tons to be released into the atmosphere every year by stirring up organically bound carbon."This is a conservative estimate compared to other studies and corresponds to the emissions from the diesel engines of the fishing fleet itself," says coastal researcher and lead author Lucas Porz from the Institute of Coastal Systems—Analysis and Modeling at ...
