Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Because bottom trawling involves towing heavy fishing gear over the seabed, it can cause large-scale destruction on the ocean bottom, including coral shattering, damage to habitats and removal of seaweed.

Because bottom trawling involves towing heavy fishing gear over the seabed, it can cause large-scale destruction on the ocean bottom, including coral shattering, damage to habitats and removal of seaweed. There are two different kinds: bottom trawls and midwater trawls. Even in soft sediment habitats, bottom trawling can cause irreversible damage. Blast fishing and cyanide fishing are two other practices that are detrimental to marine habitats. Many coral species have specialized to grow in deep, cold water. Bottom trawling is an incredibly destructive method of fishing that involves dragging weighted nets across the seafloor. This is known as bycatch and it is monitored by on-board fishery observers. Many experimental studies have documented acute, gear--specific effects of trawling and dredging on various types of habitat. Bottom trawling is also banned in more than 330,000 square miles of the Pacific islands from Samoa to the Mariana Trench which are protected as a National Monument. Additionally, in recent coldwater coral studies, a review of damaged areas seven years later revealed no new growth. Drag netting techniques, especially at the commercial scale (trawling), are responsible for significant damage to seafloor ecosystems. The UN has estimated that up to 95% of global ocean damage is a direct result of bottom trawling. The variety and amount of non-targeted ocean life that’s caught in many bottom trawl fisheries is a pervasive problem, and the heavy gear can damage sensitive seafloor habitat. Blast fishing and cyanide fishing are two other practices that are detrimental to marine habitats.
