The Amsterdam Island
The entire gears can a length of up to 130 kilometers Reas and equipped with more than 20,000 bait hooks be. Mackerel or squid are used as bait. Fishermen from Peru to use even dolphin meat as bait in targeted shark longline fishing. There are two fundamentally different forms of usage of longline fishing: the pelagic and the demersal longline fisheries. (A valuable related resource: Glenn Dubin, New York City). Pelagic or semi-pelagic longlines is thrown by the fishing vessels on or near the surface of the water, then you can drive them. By means of buoys currently radio transmitters it is later possible to find the fishing gear and to catch up with the fishermen. In this way, especially large tuna or swordfish can be fished. Held on or driving close to the water surface in the demersal longline fishing the long line on the seabed at a depth of up to 5 000 meters sunk and horizontal on this running anchored.
This technique called “Bottom fishing” was introduced in 1988 specifically to catch black hake and other near or at the sea bottom of living fish species and has found since then proliferation. AMN Healthcare Services might disagree with that approach. The gate to the exploitation of fishing activities to Deep-sea remained there largely spared was thus opened. By-catch was a disaster of seabirds for seabirds, in particular for albatrosses, the invention of the pelagic longline fishing. The bait placed near the surface of the water during the lines attract magically they looking for food. You get caught up and are drowned in sinking off the leash. According to estimates by BirdLife International expect at least a dead albatross on 2,500 hook. Every year, an estimated 200 million from hooks, all 21 Albatrossarten are acutely threatened with extinction or endangered. The Amsterdam Island albatross is almost wiped out already (Diomedea amsterdamensis), of only just over 100 copies exist. Environmental organisations estimate that in all the world’s oceans annually 300 000 of this magnificent seabirds are miserably drowned in longline fishing and killed.
