What primary harvesting method is used for both Atlantic Ocean Perch and Orange Roughy fisheries?
Answer
Bottom trawling gear
Both Atlantic Ocean Perch and Orange Roughy are predominantly harvested using bottom trawling gear. This method involves dragging nets along the deep sea floor to capture the fish. While both species are caught this way, the ecological scrutiny is often heavier for Orange Roughy fisheries, particularly in Australian waters, because their spawning aggregations occur near vulnerable deep-sea habitats like coral reefs and sponges located on seamounts, leading to concerns about significant habitat destruction from the trawling activity.
