Midwater trawling is similar to bottom trawling except the net is towed in the middle of the water column. This fishing mechanism targets schooling fish like sardines, shrimp, and squid. Like bottom trawls, turtles and whales can become entangled in the net. TEDS are required in the pelagic shrimp fishery. In the United States, pilot whales, white-sided dolphins, and bottlenose dolphins are particularly susceptible to entanglement in midwater trawling gear because they swim in this part of the water column.
