I am an experimental marine ecologist working closely with the Dutch government, Wageningen Marine Research (WMR), Wageningen University (WUR), and the Institute for Agricultural and Fisheries Research (ILVO) to unravel the ecosystem effects of electric pulse fishing and beam trawling in the North Sea. Impacts of this controversial method on the functioning of ecosystems and their biogeochemistry are relatively unknown, yet it still may be a more environmentally friendly alternative to traditional beam trawling.  My research at the NIOZ aims to shed light on the possible consequences of electrical stimulation on marine habitats and to compare and contrast these with conventional methods.

Trawl fishing leads to decreased nutrient cycling in sediments
Bottom trawling leads to lower nutrient levels and loss of invertebrate life in the upper sediment layer, and thus to a poorer seafloor. These are the conclusions from a model study of Royal NIOZ postdoctoral researcher Emil De Borger and colleagues.…

Unravelling the ecosystem effects of bottom trawling in the North Sea
The ban on pulse fishing that will be implemented from 1 July 2021, didn’t stop a young scientists’ research on the impact of the much-debated technique versus beam trawling. On Friday, 2 October, Justin Tiano (NIOZ and Ghent University) defends his…

Research on pulse trawling continues: both trawling methods affect oxygen and nutrients in seabed
The European Parliament has decided to ban pulse fishing from 1 July 2021, however, the research on the impact of pulse trawling versus beam trawling continues. Pulse trawling was developed as an alternative to beam trawling as it uses less fuel and…
