A bottom trawl is a type of fishing net that's pulled along the seafloor. Fishermen commonly use bottom trawls to catch shrimp and bottom-dwelling fish like halibut and sole. However, in addition to these target fish, the nets also catch a variety of ocean life that's usually thrown back dead or dying. Dragging heavy gear across the seabed can also damage sensitive seafloor habitat. The harmful effects of bottom trawling on bottom-dwelling organisms and their habitat can be reduced by modifying the fishing gear or limiting trawling areas.
