Jump to navigation. Bottom trawling destroys far more ocean habitat than any other fishing practice on the West Coast. In this fishing method, large weighted nets are dragged across the ocean floor, clear-cutting a swath of habitat in their wake. Some of these scars will take centuries to heal, if ever. For example, hard corals in Alaska have been dated to be hundreds to thousands of years old, and radio carbon dating on the oldest known deep sea corals indicates they are 4, years in age. Yet, these pillars of the ecosystem can be destroyed by one swipe of a bottom trawl.

Bottom trawls are highly used practices in the fishing industry. Specifically, bottom trawling is focused on harvesting the shrimp and fish that live at the sea floor. Heavy nets are dragged along, with additional weights and hard rubber wheels to collect fish. These deep sea fishing strategies are major contributors to the fishing economy worldwide. The conflict arises that over-use and over-exploitation of areas with bottom trawling and dredging can cause detrimental effects to sea floor organisms. Many issues surround bottom trawling such as the environmental impacts on the sea floor and excessive bycatch.
Bottom Trawling Impacts On Ocean, Clearly Visible From Space
At home and far out to sea, our oceans are being plundered for profit by the fishing industry. This is having devastating consequences, emptying our oceans of fish and destroying ancient ecosystems that are vital for all life in the sea. Bottom trawling is one of the most destructive forms of fishing ever devised.

Bottom trawling is considered to be one of the most destructive methods of fishing. It involves dragging heavy metal equipment along the ocean floor at high speeds in order to catch certain benthic species. In addition to destroying the seabed, trawling results in high levels of bycatch because the nets scoop up everything in its path, not just the targeted species.
