Sub-surface sets (gillnets)

Methods that reduce bycatch by eliminating gear sets at the ocean surface. These include devices such as setting chutes that place sets below the ocean surface in longline operations where they are less prone to seabird predation, and setting gillnets below the sea surface to reduce entanglement rates of small cetaceans.
