According to TRAFFIC deepwater gill netting is serious threats to sharks. It has written to the fledgling South Pacific Regional Fisheries Management Organization (SPRFMO) to express alarm that Flag States are allowing deepwater gillnetting, a potentially devastating fishing practice, of species such as deep water sharks. There is an agreement to restrict current fishing using this technique to earlier lower levels because of questions over its levels of impact on suceptible species.
It is said that delegates from 20 nations will meet next week in Auckland, New Zealand, to continue plans to establish a South Pacific Regional Fisheries Management Organization, a legally-binding body, that would have control over the high seas areas of the South Pacific Ocean from the most eastern part of the South Indian Ocean through the Pacific towards the Exclusive Economic Zones (EEZs) of South America.
Glenn Sant, TRAFFIC’s marine programme co-ordinator, said that nothing could be further from the truth. He added that the available scientific evidence points towards deepwater gillnets being extremely damaging to certain species. In 2006 the North East Atlantic Fisheries Commission (NEAFC) banned the use of gillnets in waters deeper than 200 metres, noting: “The unregulated use of gillnets in deep water is potentially damaging to deep-water stocks due to excessive soak times and consequent high discard levels, and due to the long-term impact of lost or abandoned gears.”
Ghost fishing is when lost or discarded fishing gear continues to catch fish, further depleting stocks, which are never landed. Sant points out that such nets are non-specific and impact heavily on species such as deep water dogfish and other shark species. Furthermnore, the areas targetted are vital corridors for migrant species such as school shark as they pass through ocean “bottlenecks” around the offshore Australian territories of Lord Howe and Norfolk Islands.
