Scientists Worry, The Ocean’s ‘Twilight Zone’ Faces Fishing Threat

The mesopelagic area of the ocean plays a crucial role in marine ecosystems, but it has remained largely untouched and unexplored But now some nations are eyeing the deep sea as potentially rich new fishing grounds. Virtually no sunlight reaches the deep waters of the mesopelagic zone of the ocean, which ranges from about 650 to 3,000ft (200–900m) in depth. And until now, few fishing nets have either. But that soon may change. Fishing nations are exploring the possibilities of trawling the ocean’s “twilight zone,” a vast mid-water world left largely untouched by fishing, where light-generating fish and pelagic shrimp swarm in immense masses. Norway has led the push, driven largely by a coastal aquaculture industry in need of plentiful feed for farm-raised fish. >click to read< 20:40
