"More than 50 scientists across 22 countries contribute to new study "
"A quarter of the world’s seafood caught in the ocean is collected through bottom-trawling, a method that harms seafloor ecosystems.
The technique involves dragging a net along the ocean’s shelves and slopes to gather shrimp, cod, rockfish, sole and a variety of bottom-dwelling fish and shellfish.
Other forms of marine life and habitats can be killed or disturbed unintentionally as the nets travel across the seafloor. "
