In Russian waters there are large (Far Eastern seas) or relatively small (Barents Sea) areas with restrictions or bans on bottom trawling. While such regulation certainly has a positive effect on reducing the impact of bottom trawlers on the seabed, it has little or no connection to the concepts of VMEs or sensitive habitats. The effect of bottom g...
