Albatross Task Force

At sea and on land, we're working hard to keep the world's albatross populations afloat. Find out how.
  • New trials to save albatross begin in the Argentina trawl fishery

    The status of the world’s seabirds has deteriorated rapidly over recent decades and several species and many populations are now threatened with extinction. Last information from BirdLife International’s data and assessment for the IUCN Red List reveals that seabirds are now more threatened than any other group of birds. Of the 346 seabird species, 97 (28%) are globally threatened and nearly half of all seabird species are known or suspected to be experiencing population declines. The albatross family is especially imperiled with 15 of the 22 species currently threatened with extinction. One of the main factors that contribute to declining seabird populations is bycatch in longline and trawl fisheries.

    The good news is that simple, practical measures exist that rapidly reduce seabird mortality once they are included in daily fishing operations. One of the most widely demonstrated measures for trawl fisheries is the bird-scaring line, which is deployed on either side of the vessel to create a physical barrier between the birds and the trawl cables that tow fishing nets. By preventing birds from colliding with the cables, bird-scaring lines keep birds from being struck and dragged under water.
    The Albatross Task Force in Argentina, hosted by the local BirdLife partner Aves Argentinas has been working in conjunction with several government entities; the Subsecretaría de Pesca de la Nación, the Subsecretaría de Ambiente y Desarrollo Sustentable, the Instituto Nacional de Investigación y Desarrollo Pesquero and the Universidad de Mar del Plata plus non-governmental organisation Fundación Vida Silvestre Argentina.

    The output of this collaboration has been a resolution, approved by the Federal Fisheries Council to initiate a six month programme to test the operational and logistical challenges in implementing bird-scaring lines on the vessels of the industrial freezer trawl fleet. The resolution, proposed by the Technical Advisory Committee of the National Plan of Action for seabirds, received unanimous approval with the intention to collaborate with the captains and crew to refine bird-scaring line designs that will minimise any operational concerns for the crew before the measures become obligatory in the fishery.

    According to observations conducted by the Albatross Task Force, the mortality rate of black-browed albatross in the fishery is as high as 0.237 birds per hour trawled, with a total annual trawl effort of 58,000 hours. The use of bird-scaring lines has been shown to practically eliminate this mortality in the fishery.

    In Argentina the National Plan of Action to reduce seabird bycatch calls for the use of mitigation measures for trawl fisheries and the implementation of measures that have been tested and proven. The Albatross Task Force in Argentina, with support from BirdLife International and the Royal Society for the Protection of Birds, has the main objective of evaluating seabird mortality in different fleets and developing mitigation measures to reduce levels of seabird bycatch.

  • Testing seabird bycatch mitigation: getting the facts right

    Of the 300,000 seabirds killed in longline and trawl fisheries each year, around 100,000 are albatross. This level of mortality is clearly not sustainable for these inspirational, but sadly imperilled seabirds, with 15 of the 22 species of albatross threatened with extinction.  

    Birds are killed when they scavenge baited hooks, are dragged underwater and drown in longline fisheries; or while feeding on factory discards are struck by the cables that tow trawl nets, forced underwater and drown or suffer massive trauma in trawl fisheries.

    Simple solutions exist that rapidly reduce the impact of our industrial fisheries on all seabirds:

    • Using weights to sink baited hooks from the sea surface removes them from the reach of scavenging seabirds fast enough to prevent birds from becoming hooked.
    • Bird scaring lines create a physical barrier and visual deterrent when flown behind fishing vessels and very effectively keep seabirds away from longline hooks and trawl cables.
    • As most species are less active at night, setting lines during darkness reduces interactions. Using a combination of these three measures is considered best practice for longline fisheries.

    Using good line weighting to sink baited hooks under the protection of a bird-scaring line at night is extremely unlikely to catch any birds. Flying bird scaring lines behind trawl vessels is enough to dramatically reduce seabird mortality.

    The Albatross Task Force has been working with the longline and trawl fishing industry in southern Africa and South America to test and trial these measures over the past years. Our results indicate that the effect of using these measures correctly reduces seabird bycatch by over 95%, and can even eliminate bycatch.

    We are committed to continue demonstrating how these measures can best be incorporated into the daily fishing routine, on board fishing vessels side by side with the captains and crew of the vessels. Our objective is to help industry understand the issue of seabird bycatch and become proficient in the practical use of these mitigation measures in order to achieve wide-scale adoption of seabird conservation measures.  

    An important and innovative new measure is being developed to provide a 'one-stop' alternative to the combination of three measures used in longline fisheries, which would potentially simplify policy and practice for industry. The Hook pod encapsulates the point of the hook, only releasing it beyond the dive depth of foraging birds. This week our South African Albatross Task Force instructor Bokamoso Lebepe is heading to sea on the FV Saxon to test the Hook pod in the pelagic longline fishery.

    We already know that the Hook pod can be incorporated easily into the daily routine of the fishing operation and to date our data shows a high reduction in seabird bycatch once this measure is used. We are continuing monitoring to develop a large data set that will ensure robust science backs the credentials of any new measures that we support for introduction as best practice in fisheries.  

    One of the key roles the Albatross Task Force performs, is creating a link between policy and grass roots action. By doing so the Task Force is supporting the correct implementation of best practice measures to reduce bycatch in critical sites for seabirds.

  • Back on board with the demersal longline fleet in South Africa

    I recently headed down to Hout Bay, South Africa to join a demersal (bottom) longline fishing vessel in a fishery we have recently begun working with again to improve and update mitigation measures.

    Upon arrival to the harbour I found that the boat that I was supposed to join had already left port and left me behind. This was not through any particular bad intentions, just an unfortunate miscommunication between the company and the vessel. A simple but critical difference between 12pm and 2pm! Fortunately when I got to the harbour I found that the sister ship was still in port and was due to leave in a few minutes. So I hopped on board and away we went!

    The trip was a good one, despite the usual occasional wooziness due to the mix of rough seas and small boats. I was happy to see the elusive wandering albatross soaring around our vessel in search of discarded fish. There were also large numbers of great shearwaters surrounding our vessel for the duration of the trip – I don’t remember seeing this many ever in my life. During many of my other sea trips the great shearwaters have been a rarity, but it is just a sign of the stark seasonal changes in seabird abundances.

    These smaller birds are adept divers, and in many longline fisheries they are able to dive down and bring baited hooks back to the surface where albatrosses steal the bait and become hooked and drown. This is known as secondary hooking. Gladly on this trip there were no such instances and I was able to work with the crew to improve the bird-scaring lines to help maintain the birds away from the vessel.
