Seabird deaths in Namibia’s demersal longline industry reduced by whopping 98%

The Namibian Albatross Task Force is celebrating a major conservation success story after a decade of work with the country’s fishing industry and fisheries managers.

A new paper published this week in the journal Bio-logical Conservation shows that seabird deaths in the Namibian demersal longline fishery have been reduced by 98% thanks to effective government regulation and dedicated grassroots engagement with the industry.
Bycatch – the capture of non-target species in fisheries – remains one of the biggest threats to seabirds, especially albatrosses, some of the most striking but most threatened birds globally. The RSPB and Birdlife International established the ‘Albatross Task Force’ (AT-F) in South America and southern Africa to engage directly with the fishing industry and demonstrate the simple measures that can prevent birds being caught on long-line fishing hooks or killed by collisions with the thick steel cables that haul trawl nets through the water.
In Namibia, one of the first jobs of the Task Force was to establish the scale of seabird by-catch in the riskiest fisheries. The results were rather shocking. Namibia’s hake fisheries were found to be among the world’s deadliest fisheries for seabirds: estimated at 30,000 birds killed each year, including the threatened species like the Atlantic yellow-nosed albatross and white-chinned petrels.
“It’s hard to envisage so many birds being killed in individual fisheries on an annual basis, not least for the fishers themselves who see lots of birds aggregating behind their boats and perhaps might only bring up 1 or 2 in a haul.” said Rory Crawford, By-catch Programme Manager at the RSPB. “But the cumulative effect for albatrosses in particular has been devastating – 15 of 22 species are threatened with extinction. Mercifully, this is a problem for which there are simple and elegant solutions”, says Dr Rory Crawford, the By-catch Programme Manager of the Bird-life International Marine Programme.  Since establishing the scale of the issue, the Namibian ATF has worked with the fishing industry on-board to demonstrate so-called ‘mitigation measures’ like bird-scaring lines – simple ‘scare-crow’ type rope lines paid out behind the vessel that scare birds away from baited hooks or dangerous trawl cables. After many thousands of hours at sea and in ports building support for these measures and the importance of protecting seabirds, in 2015 the team were successful in advocating for fishery regulations requiring the use of mitigation measures by law.
These news laws meant that bird-scaring lines were used across the fleet, and the new study demonstrates just how effective the potent combination of grassroots engagement and solid regulations has been.
Samantha Matjila, the Namibia ATF Team Leader with the Namibia Nature Foundation, reflected:
“It’s truly wonderful to see bycatch drop by such a huge amount in Namibia. Our waters are crucial for many globally threatened seabirds – to think that our collaborative efforts with all the vessels and the fishery managers have result-ed in more than 22,000 birds being saved every year is some-thing special. With the right levels of government investment and support, we hope that low levels of bycatch can be sustained long into the future, and that Namibia can serve as a marine conservation inspiration at a time when it is sorely needed!

The next step is to make sure that the approaches developed by the ATF are hard-wired into the long-term management of the fishery. Albatrosses are very long-lived birds (some species breed into their 60s), so conservation efforts need to be sustained over time. Titus Shaanika, Senior ATF Instructor in Namibia noted:
“The industry has done a remarkable job to re-duce seabird bycatch so substantially over such a short period. The big challenge now is to keep up those hard-earned reductions, and to wear them as a badge of honour – we can, and we must, do more of this across the world if we want turn the tide on bio-diversity loss.”
The Namibian team is the second of five ATF teams across the world to have achieved a more than 90% seabird by-catch reduction, hot on the heels of our success in South Africa in 2014 (LINK TO BLOG?). In the next two years the aim is to demonstrate similar reductions in Argentina and Chile, and to have made a major contribution to the improved conservation status of some of the world’s most remarkable – yet threatened – birds.
