Seahorses are their own worst enemy.
Fished to the point of extinction for the traditional Chinese medicine market, they mate for life and their unwillingness to seek new partners after being separated has done little to improve their chances of survival.
One of their better hopes for conservation may lie in the unlikeliest of places -- a ramshackle shed perched on the edge of the Atlantic Ocean.
Seahorse Ireland says its goal is to help save the species by cultivating seahorses born in captivity for the growing aquarium market.
"We want to make people aware that the captive-bred seahorse is a much better buy," said production manager Ken Maher, from the makeshift laboratory in Connemara, west Ireland.
"There's no deleterious effect on the environment and the seahorse will survive and flourish in your tank."
Seahorses are no ordinary sea creatures, notwithstanding their monogamy which is highly unusual for the animal kingdom. It is the male who receives eggs from his female partner and fertilizes them himself.
"The female swims up to her chosen male partner and the two change color as they dance around each other for hours in an elaborate courtship ritual," said Maher.
After receiving eggs from the female and fertilizing them himself, the male is pregnant for about three weeks before giving birth.
The low-cost technology pioneered by Seahorse Ireland could be transferred to poorer parts of the world where seahorse stocks are fast becoming depleted.
Next year, a ban on international trade in seahorses, unless they are captive-bred or for scientific purposes, is due to come into operation, a move likely to cripple the livelihoods of thousands of dependent fishermen.
"Other conservation bodies try to say `this is a sanctuary, no fishing is allowed here,' and try to get locals to make arts and crafts instead," Maher said.
"But these people are fishermen who want to live near the sea. I know I could not switch to making arts and crafts if I was in their position."
If no alternative was provided, the trade would simply go underground, Maher said.
An estimated 40 million seahorses a year are taken from the wild for traditional Chinese medicine in which they are used as an aphrodisiac as well as a range of ailments including heart disease.
Demand has risen in recent years to such an extent that seahorses retail for about US$1,900 a kilogram in Asia, almost the price of gold.
A further one million are fished for the curio trade because seahorses retain their shape and color when dried.
The pet trade takes another one million, but very few survive beyond a few months or so without live food.
That's where Seahorse Ireland comes in -- it trains captive-born seahorses to get used to frozen food.
"Once we train them to take frozen food, they can be sent all over the world," said Maher.
Set up three years ago by Maher and his fellow marine biologist Kealan Doyle, Seahorse Ireland has two key advantages right on its doorstep.
First, the larger of the two seahorse species local to Ireland, the spiny seahorse, can be found in seagrass beds in and around nearby Kilkieran Bay.
In addition, the west coast of Ireland offers an abundance of zooplankton enriched by nutrients from the Gulf Stream, and the company has developed a system to extract and freeze this food.
Maher dismissed criticism from some environmentalists that breeding seahorses in captivity will serve only to boost demand, heaping more pressure on rapidly-declining stocks.
Capable of spawning 200 offspring at a go in the wild, with the right conditioning seahorses could breed closer to 1,000 juveniles, Maher said.
The company aims to sell seahorses for the pet market, retailing from 200 euros each, over the Internet, to be dispatched for next-day delivery.
"Seahorses travel quite well in tightly packed bags, with oxygen, just like goldfish," Maher said.
Sales are forecast at around 30,000 next year and around 70,000 the year after. Over time, Maher said there were plans to open a visitor center, using the seahorse as an icon for other endangered species.
"We will use it as a focus for conservation because it's not just the panda in China or the river dolphin in India that are in need of help," he said.
Sept. 21 to Sept. 27 If word got out that you were planning a wedding during the Martial Law era, the “Committee for the improvement of Folk Customs” (改善民俗實踐會) might knock on your door. Each borough in Taipei had at least one “agent” who kept a pulse on community happenings. They would visit the family planning the wedding with a letter from the mayor, touting the benefits of being frugal and not wasting money on lavish ceremonies, even encouraging the families to donate money for scholarships. The authorities also discouraged them from hiring musicians and dancers, who were often loud and
Community-supported agriculture (CSA) is a way urban households can obtain healthy produce, while helping to build a more sustainable farming sector in Taiwan. King Hsin-i’s (金欣儀) transformation from advertising copywriter to social entrepreneur began in 2008, when she visited a rice farmer who practiced pesticide-free agriculture. “He explained that we have to leave space for other species. At the same time, I realized that while big companies have budgets to spread their messages, farmers have few chances to tell the public about their beautiful concepts,” she recalls. Inspired, she quit her job and traveled throughout rural Taiwan for a year. King went
Every day before she starts her shift at a government hospital in Singapore, Farah removes her hijab — the Islamic veil she has worn since a teenager. Although minority Muslim women can freely wear the hijab in most settings in Singapore, some professions bar the headscarf — and a recent case has triggered fresh debate on diversity and discrimination in the workplace. Now Farah has joined a growing number of Muslims — who account for about 15 percent of Singapore’s 4 million resident population — calling for the ban to end, with an online petition gathering more than 50,000 signatures. “They told me
If ever there was a reason to be inside on Mid-Autumn Festival, even for just an hour or so, while still celebrating the natural world, Cheng Tsung-lung (鄭宗龍) has provided one with his first full-length work for Cloud Gate Dance Theatre (雲門舞集) as artistic director, Sounding Light (定光). Judging by the excerpt performed for the press last week, Cheng shows he can be just as minimalistic as his mentor, troupe founder Lin Hwai-min (林懷民), while still forging his own unique path. Just as he did with last year’s Lunar Halo (毛月亮), his final work as director of Cloud Gate 2 (雲門2), Cheng
