NAMIBIA SEES A REDUCTION INSEA BIRD BY-CATCHA juvenile Black-browed Albatross caught on a baited hook. The bird was released by Albatross Task Force.

The subsequent "knock-on effect" of capitalising on these natural marine resources has, by scientific accounts, resulted in several detrimental impacts, one of which relates to the immense avian bycatch that, prior to 2015, saw the mortality rate of seabirds reach 20000 to 30000 bird's each year. The abundant Hake and Monkfish populations have provided jobs aboard a fleet of fishing vessels and processing plants for Namibians and assisted in stabilising a local economy which traditionally relied upon seal and whale hunting to support its people. Legislation changed what would mean the "end of the line" for several threatened or endangered species in 2015. The short span of 7 years has provided a consensus on the practicalities brought about through mindful planning. The demersal hake trawlers and longline fishing vessels that inadvertently cause unnecessary deaths of up to 40% of the global yearly marine catch which is discarded as waste, have provided a benchmark as the number of incidents has decreased by up to 98.4% in reference to longline fleets, and similar results have been seen on trawling vessels. An article highlighting the pertinence of safeguarding Namibia's avian species was published in 2017 and outlines what we can now herald as systematic governance for many of the challenges we still face to steadily halt the destruction of our planet. Namibia’s low cost, sustainable solution to seabird bycatch by William H. Funk First published in Mongabay.com, April 25, 2017
Accidental take of marine animals by commercial fisheries is a serious global environmental problem, with 40 percent of the world’s ocean fishing totals disposed of as bycatch annually.
Roughly 63 billion pounds of unwanted wildlife — seabirds, marine mammals and sea turtles, countless fish species, rays, and cephalopods — are killed as bycatch due to the swallowing of baited hooks or entanglement in nets.
Namibia, once known as the “world’s worst fishery” regarding avian bycatch is addressing the problem. It has installed “bird-scaring” lines on the nation’s 70 trawlers and on its 12 longline fishing vessels and has also adopted other low-cost methods to minimize avian bycatch, which once killed more than 30,000 birds annually.
The Meme Itumbapo Women’s Group, known for its seashell necklaces and other jewelry, is now sustainably manufacturing, and supplying the bird-scaring lines from their headquarters “Bird’s Paradise,” in Walvis Bay, Namibia. The hope is that these combined efforts will reduce avian bycatch by 85-90 percent in the near future.
Many years ago, I joined my cousin, the mate on a sporting vessel, on a fishing trip off the North Carolina coast. We were trolling baited lines in hopes of catching striped bass. I was in the wheelhouse when a mighty expletive arose from one of the three paying client fishermen. Looking astern, I saw a large white bird floundering in the sea — it had dived to take one of the towed baitfish and now was hooked.
The client angrily jerked the rod, reeling in the struggling animal, a Northern Gannet. The bird, once on deck, was judged to have swallowed the hook. The captain moved swiftly to cut the line and toss the doomed bird overboard, but before he could act, I asked to examine the bird. He handed it over, all seven struggling, kicking, flapping pounds of it. The bird’s face, so close to my own now, was striking; its desperately clacking chisel-like bill, a slight taupe tincture at the top of the head and staring white eyes ringed in startling turquoise.
With the captain’s help, I pried the bill open and found that the hook hadn’t been swallowed but was merely caught in the bird’s throat. Using pliers, I reached into the wildly vocalising mouth, seized the hook and with a quick downward motion removed it. The captain immediately, and with unexpected delight, hurled the bird high into the air, and we all watched silently as it departed our company at top speed. The client who’d been so enraged at the bird’s interruption of his fishing exclaimed quietly: “Man, that was… really something.” The critically endangered Tristan Albatross (Diomedea dabbenena).

Unfortunately, this Northern Gannet was one of the few lucky victims of bycatch. Most of the billions of animals swept up accidentally by commercial fishermen and sport anglers every year die. But in faraway Namibia, they’ve found a simple solution to the problem the rest of the world could tune to as an inspiration and example.
The waste of bycatch Accidental take of marine animals by commercial fisheries is a serious but largely unsung global problem, with a breath-taking 40 percent of the world’s marine fishing haul essentially disposed of as garbage annually. That’s roughly 63 billion pounds of unwanted wildlife — seabirds, marine mammals and sea turtles, countless fish species, rays, and cephalopods — inadvertently killed by swallowing baited hooks or getting entangled in nets.
This bycatch, as it is called, suffers the fate that our Northern Gannet nearly experienced. All 63 billion pounds of marine animals, usually dead or dying, is thrown overboard, a tremendous waste of wildlife, that until fairly recently was casually taken for granted.

Turtle Excluder Devices or TEDs, for example, have been required in the United States since 1987, with the nets of shrimping boats mandated to include a metal grid that allows shrimp to pass through while blocking the turtles, sharks and other large animals that otherwise would be rendered as bycatch — this allows the unwanted animals to escape unharmed through a vent at the top or bottom of the net.
This is a promising technological achievement for a rich country that long neglected its bycatch problem. But financially strapped nations in the developing world have been slow to follow with bycatch prevention equipment, or with the governmental programs needed to get it installed and accepted by traditional, often very conservative fishermen. Namibia leads the way in battling seabird bycatch Little-known Namibia, in Southwest Africa, could well be the nation that is currently leading the pack in protecting seabirds, a particularly interesting happening considering that the country was previously known as the “world’s worst fishery” in terms of avian bycatch.
Namibia’s fishermen are usually going after Hake, a cod-like fish that constitutes around 50 percent of the country’s N$11 billion (US$845 million) fishing industry. However, in the process, commercial fishermen have been killing more than 30,000 seabirds as bycatch every year, including the Tristan Albatross (IUCN Red Listed as Critically Endangered); the Atlantic Yellow-nosed Albatross (Endangered); Black-browed Albatross and Shy Albatross (both Near Threatened); and the White-chinned Petrel and Cape Gannet (both Vulnerable).
Albatrosses are the most highly threatened group of birds on earth, and at Namibia’s level of accidental take, the country’s fishing industry was on the way to playing a major role in helping these bird species spiral to extinction.

Last spring, she enrolled in a program that the ATF, which is hosted by BirdLife International, had been conducting in Namibia since 2008, but which has been ramped up since the Namibian government introduced tight new regulations in 2014 to mandate the use of bycatch abatement equipment on all commercial fishing vessels, with a fine of N$500,000 (US$38,400) and up to ten years in prison awaiting violators.
Matjila’s job is to show fishermen how to fit the various devices used to avoid bycatch to a boat’s fishing gear. Then she accompanies the fishermen out to sea to show them how the gadgets work in practice.
The anti-bycatch tools are quite simple and easy to use, and include “bird-scaring” lines (also known as tori lines or streamers) that are being used by the nation’s 70 trawling vessels. Bird-scaring lines, along with line-weighting and nocturnal baiting techniques, are used by Namibia’s 12 longline fishing vessels.

Albatrosses, some of which can live for 60 years, are caught and drown when they attack a baited hook before it can sink out of their diving range. The bird-scaring lines consist of 150-meter-long ropes with brightly colored streamers placed two or three meters apart. Line-weighting involves the placement of additional weighted sinkers on each line so the bait sinks more rapidly while setting a longline — a miles-long main line with as many as 2,500 baited hooks dangling from shorter lines. These lines are also set out at night to prevent the bycatch of diurnal Albatrosses.
Across the border in South Africa, where the ATF has been working with fishermen since 2006 using the same simple techniques, the successes have been astounding, with a decline of over 90 percent in seabird bycatch. Similar success is being seen in Namibia, with the ATF hoping to reach an 85-90 percent reduction in bycatch in the near future.
The ATF first worked with volunteer Namibian fishermen in 2008, says Matjila. “We didn’t know what the impact of Namibian fisheries would be back then, but we knew there was an overlap of where Albatrosses roam and where the vessels set their hooks. We also knew that simple, practical measures existed that could reduce seabird deaths.”
But what about hostile reactions to new regulations (something seen at first when TEDs were introduced in the U.S.)? “Working with the fishermen and sharing in discussions with them about the bycatch law, it is safe to say that, yes, they are very accepting as they realize the benefits of the mitigation measures introduced to them,” Matjila says.

Oliver Yates, BirdLife International’s Global Albatross Task Force Coordinator, says that today, “close to 100 percent of vessels carry observers. This is particularly good coverage and makes Namibia a perfect example of how this could/should work effectively,” around the globe.
Saving birds through a sustainable economy It’s not just seabirds that benefit from Namibia’s program. According to Matjila, “The fishing companies purchase bird-scaring lines produced by a local organisation called the ‘Meme Itumbapo Women’s Group.’ Meme Itumbapo is a consortium of five women, aged 33 to 47, who generate a small income from traditional jewellery sales. These women also now manufacture and supply the bird-scaring lines for the longline and trawling fisheries from their headquarters ‘Bird’s Paradise,’ in Walvis Bay, a coastal city.

These hardworking and adaptable women shifted easily from stringing together beautiful necklaces made out of seashells to supplying ten percent (so far) of the equipment needed by Namibia’s fishing fleet to save seabirds — an example of sustainable, affordable conservation, as well as gender equality.
The ATF is now promising that, “Their hand-built, quality-assured, local, affordable lines will be flying off the back of more and more Namibian fishing boats in the next two years.”
Clemens Naomab was one of the ATF’s first Namibian anti-bycatch trainers. He tells how he earned the trust of often insular and independent fishermen: “Namibians like to watch European football, especially the English premier league,” he explains. “Most of our relationships are developed by trading stories about football. When you have a good relationship with the fishermen it is easier to communicate with them.” Using the universal language of sports, Naomab broke through barriers and earned a place alongside his fishermen buddies, who all quickly absorbed his instructive and useful lessons and mastered the skills needed to save seabirds. “Most of the fisherman are quick to adopt the measures once you explain to them the procedures and what is required of them,” he says.
Naomab adds: “I have always loved nature and everything that comes with it,” which is why he eagerly accepted his job with the ATF, a move he initially regretted when he realised he was prone to seasickness.

Now he laughs off those early days of misery at sea, saying that, “My first few trips were hard, because I used to get really sick. At first I didn’t know much about seabirds, actually I never thought I would be involved with seabirds. As time passed, I started noticing how beautiful and majestic these birds are, and at the end of the day all those sleepless nights on the fishing vessels were worth it.”
The initiative mandate is founded on regulations that give a practical and cost-effective means by which to alleviate the wasteful destruction of avian species through using bird scaring lines and bright streamers attached to trawl cables and bated hook lines. Several migrant albatross and large Petrel species have seen significant population numbers fall at an alarming rate; however, since the introduction of these bird-scaring safeguards, a noticeable increase of breeding aged adults has given rise to renewed hope for these majestic birds. In 2018, the estimated avian deaths caused by Namibian long liners numbered around 215 as opposed to 2009, where a staggering value of 30000 deaths was reported. The concerns surrounding any industrial or commercial interactions between humans and nature typically result in nature and the animals, more specifically avian species in the case of Namibian fisheries, bearing the burden of man's unscrupulous greed. Scientific research-based data coupled with an inclusive fundamental planning procedure has succeeded in providing a tactile framework by which drastic seabird mortality has been dampened and embraced by industry in light of a better understanding that considers the impact man has on nature.
