Japan is losing out in the Pacific fish wars

Seafood-hungry nations like China and the US are muscling into prime waters

TOKYO In a time of rising military tensions, the world is already at war over fish, and seafood-loving Japan is finding itself on the losing side as fish-hungry economies like China, North Korea, Taiwan and the U.S. pursue ever bigger catches.

It is increasingly difficult for Japan to ensure steady supplies of seafood to homes and restaurants, and even inexpensive species used for general consumption, such as mackerel and squid, have become less affordable.

SUNSET INDUSTRY The home of sushi and sashimi, Japan was once the world's pre-eminent fishing nation, processing the largest ocean catch for 16 consecutive years until 1987. It has never regained the top slot, and its fishery output, including aquaculture, has fallen back to around 4 million tons from a peak of 12 million tons.

The world's per capita consumption of fish and shellfish has more than doubled over the past half century, fueled by increasing health consciousness, particularly among U.S. and European consumers, and rising demand from emerging economies.

China has developed a particularly strong appetite and is now the world's biggest consumer of seafood. With a population of over 1.38 billion, the world's most populous country has seen its catches swell by over 20% in the past five years. Fisheries closest to its shores have suffered from overfishing and industrialization, however.

Chinese fishermen sail the world in search of new grounds, bringing them into contact with their Japanese and South Korean counterparts. Chinese media sometimes depict this as a maritime version of ancient China's Three Kingdoms, which fought a fierce three-way battle for supremacy.

DWINDLING CATCHES In mid-August, the saury fishing fleet at the Japanese port of Hanasaki in Nemuro, Hokkaido, returned at dawn with the first full landing of saury, or mackerel pike, of the year. The combined catch was 700 tons. A senior official from the Hokkaido saury fishery association was unhappy with the "slender" fish he beheld. The silvery saury used to weigh around 150-180 grams apiece, but now they average about 120 grams -- less than sardines.

The problem is as much about quantity as weight. According to the national saury association, the landed volume fell to a record low of 109,000 tons in 2016 -- half the 2014 figure, and a third of 2008. Reasons for the decline include higher seawater temperatures. Yet China and Taiwan have both had record saury catches, according to the Tohoku National Fisheries Research Institute.

Three or four years ago, fleets of large Chinese and Taiwanese boats started appearing outside Japan's 200-nautical-mile (370km) exclusive economic zone off Hokkaido and elsewhere. The vessels had state-of-the-art equipment, including "tiger nets" that are used in conjunction with underwater lights to boost catches.

The Chinese do not have a big history of eating saury, so why the increased catches? Takeshi Hamada, a professor at Hokkai-Gakuen University in Hokkaido, said the number of Chinese saury vessels increased after a massive earthquake and tsunami devastated northeastern Japan on March 11, 2011. The earthquake also caused the Fukushima nuclear disaster.

Japan had been exporting saury and mackerel to Russia, where they are widely consumed as canned food. Russia cut off Japanese fish imports after the 2011 disasters and looked to China and Taiwan to fill the gap. "Japan was deprived of both fishing grounds and business," Hamada said.

In mid-July, the North Pacific Fisheries Commission held a saury conference in Sapporo, Hokkaido, to discuss overfishing of the North Pacific. Japan proposed the introduction of country quotas, but China, with support from Russia and South Korea, strongly opposed the idea. The proposal failed.

Masanori Miyahara, president of the Japan Fisheries Research and Education Agency, attended the conference and remains pessimistic. "Our efforts to persuade China face a rocky road ahead," he said. Talks on ways to prevent overfishing are due next year, but sharp differences remain.

ILLEGAL AND DANGEROUS Japanese bonito and squid fishermen also face tougher foreign competition. Kesennuma in Miyagi Prefecture, which bore the brunt of the 2011 earthquake, has been Japan's biggest bonito port for 20 years straight. In the July-October peak season, daily landings once ranged from 500 to 1,000 tons but have now dropped to no more than 400 tons, according to the local fishery association.

Bonito, or skipjack tuna, is sold as canned tuna and pet food, among other things, and is being fished increasingly intensively in the rich waters of the South Pacific by vessels from China, Taiwan, and the U.S., according to Katsukura Gyogyo, a fishing company based in Kesennuma. The boats there have grown bigger by the year and are fitted out with the latest equipment to lure and process fish. The price of frozen bonito has roughly doubled in the past two years to around $2,000 per ton on the Bangkok market, which sets the international benchmark.

In July, North Korean vessels were found by fishermen from Fukui Prefecture operating illegally in Yamatotai, an area in the Sea of Japan known to be rich in sweet shrimp and squid. "It is so dangerous that we cannot fish there," said one fisherman. The North Koreans use drift nets to catch squid, and only turn on very small lights at night, raising the risk of collision. Japanese sweet shrimp hauls this summer were down 20% on the year, partly due to voluntary restraint. Local fishermen want the authorities to crack down on the North Korean vessels illegally -- and dangerously -- entering Japan's EEZ.
