The least-impacted places in the ocean are mainly in the deep sea, but as fishing technology has improved, even seamounts, sponge gardens and deep-sea coral beds are no longer out of reach of our appetites for seafood. Bottom trawling, which involves dragging a heavy weighted net along the seabed, is so destructive to benthic habitats that it has been compared to clear-cutting a forest. Bottom gillnetting catches almost anything that swims into them (and isn’t smaller than the mesh size), resulting in enormous levels of bycatch.

The deep-sea fishing fleet of the European Union is one of the largest in the world, which is why it was so heartening to see the European Commission call for a phase-out of trawls and bottom gillnets recently. The Marine Conservation Institute, a longtime leader in marine protected areas, has obtained over 100 signatures (including mine) from marine scientists supporting a phase-out of bottom trawls and bottom gillnets by the EU fishing fleet. If you are a scientist who supports this measure, please consider adding your signature. This can be done by e-mailing [email protected] and including your name, institutional affiliation, degree, title, and full mailing address. Please note that MCI is primarily interested in signatures from the scientific community, and that simply posting a comment on this blog post is not equivalent to signing the petition.However, feel free to post a comment letting us know that you contacted MCI!
