Fish Poachers in Africa

In Sierra Leone nearly half the population does not have enough to eat, and fish make up most of what little protein people get. But the country’s once-plentiful shoals, combined with its weak government, have lured a flotilla of unscrupulous foreign trawlers to its waters. Most of the trawlers fly Chinese flags, though dozens also sail from South Korea, Italy, Guinea and Russia. Their combined catch is pushing Sierra Leone’s fisheries to the brink of collapse.

Sierra Leone is not alone in facing this crisis. According to the UN’s Food and Agriculture Organisation, 90% of the world’s fisheries are dangerously overexploited. The Africa Centre for Strategic Studies, a think-tank funded by America’s defence department, reckons that about a quarter of fish caught off Africa’s shores are taken illegally.

Ecological Hooliganism: smashing the coral triangle

Giant clams are one of Buddhism’s “seven treasures”, along with gold and lapis lazuli. China’s new rich prize their shells as showy ornaments. Each can fetch as much as $3,000, so each haul was worth a fortune to the fishermen of Tanmen, a little fishing port on the island province of Hainan in Southern China.  But Chinese government banned the clam fishing…
The ban is surely welcome. [S]ome of the most biodiverse coral reefs on Earth have been destroyed in the South China Sea thanks to giant-clam poachers. In the shallow waters of the reefs, crews use the propellers of small boats launched from each mother-ship to smash the surrounding coral and thus free the clams anchored fast to the reef. Though the practice has received little attention, it is ecological hooliganism, and most of it has been perpetrated by boats from Tanmen.

The fishermen have not been the reefs’ only adversaries. China’s huge and (to its neighbours) controversial programme since late 2013 of building artificial islands around disputed rocks and reefs in the South China Sea has paved over another 22 square miles of coral. When the two activities are taken together, Mr McManus says, about 10% of the reefs in the vast Spratly archipelago to the south of Hainan, and 8% of those in the Paracel islands, between Hainan and Vietnam, have been destroyed. Given that Asia’s Coral Triangle, of which the South China Sea forms the apex, is a single, interconnected ecosystem, the repercussions of these activities, environmentalists say, will be huge…

But still..A few streets back from the waterfront in Tanmen, elegant boutiques sell jewellery and curios fashioned from the giant clams—and clam shells are still stacked outside. And the provincial money that is so clearly being lavished on Tanmen sits oddly with the illegality of its townsfolk’s way of life. .. [I] n 2013 President Xi Jinping himself showed up in Tanmen. Boarding one of the trawlers he declared to the crew, according to state media, “You guys do a great job!” The media did not report that a year earlier the trawler in question had been caught in the territorial waters of Palau, and in the confrontation with local police that followed one of the crew members had been shot dead. In Chinese propaganda, Tanmen’s fishermen are patriots and model workers.

Over the years Tanmen’s fishermen have become part of China’s power projection in the South China Sea, an unofficial but vital adjunct to the Chinese navy and coastguard. The biggest trawlers are organised into a maritime militia ready to fight a “people’s war” at sea. Though generally unarmed, they undergo training and take orders from the navy.

They are facts on the water, and have been involved in China’s growing aggression in the South China Sea. In 2012 boats from Tanmen were part of a navy-led operation to wrest control of Scarborough Shoal from the Philippines, chasing Philippine fishing vessels away. In 2014 they escorted a Chinese oil rig that was being towed provocatively into Vietnamese waters. On land, Vietnamese expressed their rage by ransacking factories they thought were Chinese-owned. At sea, boats from Tanmen rammed and sank one of the rickety Vietnamese vessels coming out to protest.

Mysteriously, though, the giant trawlers of the Tanmen militia are now rafted up, their crews sent home. Perhaps China is keen to lower tensions in the region….A policy introduced in January aims to cut the catch from China’s fishing fleet, the world’s largest, by a sixth, in the name of sustainability. That will hit Tanmen’s fishermen hard, making them less willing to defend China’s claims. Francis Drake would have understood: pirates are patriotic, but usually only when it pays.

Fishing to Death

Fishing vessel. image from wikipedia

Under international law the high seas, which span 64% of the surface of the ocean, are defined as “the common heritage of mankind”. This definition might have provided enough protection if the high seas were still beyond mankind’s reach. But the arrival of better trawlers and whizzier mapping capabilities over the past six decades has ushered in a fishing free-for-all. Hauls from the high seas are worth $16 billion annually. Deprived of a chance to replenish themselves, stocks everywhere pay the price: almost 90% are fished either to sustainable limits or beyond. And high-seas fishing greatly disturbs the sea bed: the nets of bottom trawlers can shift boulders weighing as much as 25 tonnes….

A fresh approach is needed. Slashing fishing subsidies is the most urgent step. In total these come to $30 billion a year, 70% of which are doled out by richer countries. By reducing fuel costs, subsidies bring the high seas within reach for a few lucky trawlers, largely from the developed world. Just ten countries, including America, France and Spain, received the bulk of the bounty from high-seas catches between 2000 and 2010, even though Africa has more fishermen than Europe and the Americas combined. That is unfair and short-sighted.

The next step is to close off more areas to fishing. As of 2014 less than 1% of the high seas enjoyed a degree of legal protection. A review of 144 studies published since 1994 suggests that to preserve and restore ecosystems, 30% of the oceans should be designated as “marine protected areas” (MPAs). Individual countries can play their part, by creating reserves within territorial waters: last year Britain created the world’s largest MPA, an area bigger than California off the Pitcairn Islands in the South Pacific. But to get anywhere near that 30% share, mechanisms must be found to close off bits of the high seas, too. The UN’s members have rightly agreed to work out how to do so…

So in parallel with efforts to protect wild stocks, another push is needed: to encourage the development of aquaculture, the controlled farming of fish. In 2014, for the first time, more fish were farmed for human consumption than were caught in the wild; farmed-fish output now outstrips global beef production. Unfortunately, feedstocks are often poor and storage facilities inadequate. …Eventually, efficient fish-farming will be the best guardian of stocks on the high seas.

Vaquita and Totoaba–endangered fish as delicacy

fish bladder factory californa

The most recent estimate puts the remaining numbers of vaquita, a porpoise found only in the waters of the Sea of Cortés, Mexico, at just 60, down from 100 two years ago…. The vaquita has been a victim of the shrimp and totoaba fisheries, showing up as bycatch in gillnets.

The totoaba is also an endangered species but its swim bladder is a delicacy in China, selling for as much as US $5,000 per kilogram in the U.S. and a great deal more in China. The matter has been taken up by Agriculture Secretary José Calzada Rovirosa with Chinese officials in an effort to stop the illegal consumption of the bladders.  Vaquitas are not only being killed by totoaba fishing. When illegal fishermen are pursued by the Mexican Navy, they often cut their nets and set them adrift, becoming an additional threat to the porpoise.

Removing these “ghost nets” will be one of the steps taken before the implementation of an assisted breeding program, said marine mammal expert Lorenzo Rojas Bracho from the National Institute of Ecology and Climate Change.

There are doubts about the feasibility of a breeding program as well as concerns about the risk. “We have no idea whether it is feasible to find, capture and maintain vaquitas in captivity much less whether they will reproduce,” said vaquita expert Barbara Taylor of the U.S. National Oceanic and Atmospheric Administration.

When States Fail: Illegal, Unreported and Unregulated Fishing

Nouakchott, Mauritania air picture image from wikipedia

Mauritania has some of West Africa’s richest fishing waters yet overfishing by foreign trawlers means hundreds of pirogues, or wooden canoes used by small-scale fishermen, must go further out to sea to net ever smaller catches.  Fishing is an important part of the mostly desert country’s economy, accounting for seven percent of gross domestic product and providing about 40,000 jobs, according to the World Bank…

West Africa alone loses at least $1.3 billion a year from illegal, unreported and unregulated fishing, according to a 2014 report by the Africa Progress Panel, which campaigns for sustainable development in Africa.Widespread corruption and few resources for enforcement mean huge foreign trawlers often venture into areas near the coast which are reserved for artisanal fishermen.  This allows them to drag off tonnes of catch in waters rich in snapper, sardines, mackerel and shrimp – putting the livelihoods and food security of millions of locals at risk…One way of improving governance is for more information to be disclosed on the quotas being sold to foreign fishing firms and how licensing agreements are being implemented,..

[T]he Extractives Industries Transparency Initiative (EITI) [is] a pioneering project that sets standards for companies to publish what they pay for oil, gas and minerals and for governments to disclose what they receive.  Modelled on EITI, a Fisheries Transparency Initiative (FITI) is in the works with Mauritania due to announce this week that it has set up a group of government officials, industry figures and campaigners to promote transparency in fisheries contracts….

“Transparency is just one component,” said Andre Standing, who works for the Coalition for Fair Fisheries Arrangements.”A lot depends on how people are able to use that information and whether they can put pressure on governments and companies to change behaviours where needs be,” he told the Thomson Reuters Foundation.

How Palau Fights the Big Fishing Countries

Palau

The traditional prescription for an ailing reef is a fishing ban called a bul. Local chiefs may declare a bul to rest a busy fishing spot or protect endangered sea turtles. Now Palau’s president has a more drastic plan. He proposes a complete ban on commercial fishing—a bul to turn the 600,000 square kilometres (232,000 square miles) of Palau’s Exclusive Economic Zone (EEZ) into a marine reserve the size of Ukraine. Locals could still fish close to shore, but not for export. The ban would last until world leaders implement programmes “to reverse the devastation to our oceans and seas”, Palau’s president, Tommy Remengesau, recently told the United Nations. Environmentalists have rallied to his cause. Such reserves are usually declared by countries with fishing grounds and cash to spare. Palau has a population of 20,000 and a GDP of $246m. I

A total ban might hurt Palau, which is part of Micronesia, 800km (500 miles) east of the Philippines. Though small, its waters are full of bigeye and yellowfin tuna. Japanese and Taiwanese boats pay to fish there, helping Palau earn $5m in revenue from fishing taxes and licensing fees in 2013. That is a lot for a microstate with an annual government budget of only $70m. And fishing revenues have been growing thanks to a regional negotiating block. Together, eight remote Pacific states control 14m square km of tuna-rich waters. They have forced Asian and American ships into a cap-and-trade scheme that boosts access fees by limiting total fishing days. In an age of collapsing fish stocks, the relative health of fisheries in the western Pacific has given island states a rare measure of economic influence. Palau’s bet, however, is that its fish are worth more in the water than out. Mr Remengesau doubts that small islands will ever capture more than “a drop” of a tuna fishery worth billions but dominated by foreign fleets. Ecotourism, meanwhile, accounts for about half of Palau’s GDP. Palau’s leaders hope that a national marine reserve will lure enough tourists to offset lost fishing revenue….

Palau has only one boat capable of patrolling its EEZ. Many tuna bandits escape detection. Technology could help: last year the country tested surveillance drones. The problem is money. Japan and America have helped fund enforcement. Both have an interest because of their fishing deals with Palau. But they may not want to fund a system that locks them out of its waters altogether,

Marine Protected Areas: PIPA, Kiribati

Phoenix islands Protected Area.  Image from wikipedia

After years of claiming untruthfully that the world’s most fished marine protected area was “off limits to fishing and other extractive uses,” President Anote Tong of the Pacific island state of Kiribati and his cabinet have voted to close it to all commercial fishing by the end of the year.  The action, if implemented, would allow populations of tuna and other fish depleted by excessive fishing to return to natural levels in the Phoenix Islands Protected Area (PIPA), a patch of ocean the size of California studded with pristine, uninhabited atolls.

The move comes at a time global fish populations are steadily declining as increasingly efficient vessels are able to extract them wholesale from ever-more-remote and deep waters around the globe.  While no-take zones of comparative size exist in Hawaii, the Chagos Islands and the Coral Sea, none are as rich in marine life, making this potentially the most effective marine reserve in the world.,,,

In a speech still he gave at the Delhi Sustainable Development Summit two years ago still visible on Youtube, Tong mentions “the initiative of my country in closing off 400,000 square kilometres of our [waters] from commercial fishing activities,” calling it “our contribution to global ocean conservation efforts.”

In fact, when PIPA was created, only in the three percent of the reserve that’s around the islands, where virtually no fishing was going on, fishing was banned. In the rest of the reserve, the catch increased, reaching 50,000 tonnes in 2012 – an unheard-of amount in any protected area.
