Bottom trawling destroys complex seabed habitats including cold-water coral reefs that support thousands of species and provide essential fish nursery habitat.
Bottom trawling causes mass mortality and habitat destruction for countless benthic organisms including corals sponges worms molluscs and crustaceans. While individual welfare of sessile organisms is less clear, the destruction of entire communities and the fish nursery habitat they provide has cascading welfare effects for mobile animals that depend on these ecosystems. The scale and pace of seabed destruction is ecologically catastrophic.
