A conservationist in Kinmen County is determined to save species of fish endemic to the islands, no matter the size.
Chen Kuang-yao (陳光耀), director of the Kinmen Wildlife Rehabilitation and Conservation Association, has dedicated himself to saving the many unique species that live in and around the outlying islands.
He has recently turned his sights to Metzia mesembrinum, a type of minnow, which Chen said is “nothing special,” but faces imminent extinction.

The freshwater fish cloaked in subdued browns and grays grows as long as 4.8cm, but only in Taiwan.
It disappeared from Taiwan proper more than a century ago, leaving Kinmen as the only place where it can be found in the wild.
Chen said that there are only about 10,000 left, primarily in the Guangcian (光前溪) and Doumen (斗門溪) creeks.

Yet in the short time between Chen’s last two surveys, it appears as though they have already disappeared from Doumen Creek, mainly due to drought conditions.
Kinmen has been experiencing its worst drought in 50 years, posing a threat to many aquatic species, Chen said on Tuesday last week.
Farmers have been rerouting what little water there is to irrigate their crops, leaving none for the fish, he said.
“Fish are not like other animals; they cannot move to another habitat,” he said. “If Metzia mesembrinum disappear from Kinmen, they will have disappeared from the Earth.”
Some rehabilitation efforts have preserved a small number of them, but the situation remains dire, he added.
This led Chen to reach deep into his own pockets to start what he calls a “fish reclamation workshop” committed to protecting the last of the world’s Metzia mesembrinum.
The workshop has three breeding tanks which hold about 300 of the fish as a “reserve fund.”
If they go extinct, these 300 fish could be released back into the wild to repopulate the island, Chen said.
He has also spared no expense on the NT$5 million (US$180,375) facility, all the way down to the high-protein eel food he purchases as feed.
All told, the workshop costs him about NT$50,000 per month, but Chen said that it is worthwhile.
“They might not look special, but each species has value,” he said. “If we preserve them, they will be there for the next generation.”
This is why he insists on conservation and rehabilitation, Chen said, because “an animal saved is an animal gained.”
Apart from Metzia mesembrinum, Chen also works tirelessly to preserve other rapidly disappearing fish species native to Kinmen.
Long after disappearing from the county’s main island, Chen rediscovered the climbing perch, or Anabas testudineus, in neighboring Lieyu Township (烈嶼).
He also managed to catch a rosy bitterling, which had been thought to be extinct from Kinmen for more than 20 years, both of which are also being rehabilitated at Chen’s workshop.
Chen said he is still chasing his own personal white whale.
The Snyder’s barb, or Barbodes snyderi, has not been seen in the wild for nearly two decades.
Chen said he has searched all over the county, including for three straight days in Cingtian Reservoir (擎天水庫), but the fish still eludes him.
Even after 10 years, he said he would keep looking.
‘DENIAL DEFENSE’: The US would increase its military presence with uncrewed ships, and submarines, while boosting defense in the Indo-Pacific, a Pete Hegseth memo said The US is reorienting its military strategy to focus primarily on deterring a potential Chinese invasion of Taiwan, a memo signed by US Secretary of Defense Pete Hegseth showed. The memo also called on Taiwan to increase its defense spending. The document, known as the “Interim National Defense Strategic Guidance,” was distributed this month and detailed the national defense plans of US President Donald Trump’s administration, an article in the Washington Post said on Saturday. It outlines how the US can prepare for a potential war with China and defend itself from threats in the “near abroad,” including Greenland and the Panama
The High Prosecutors’ Office yesterday withdrew an appeal against the acquittal of a former bank manager 22 years after his death, marking Taiwan’s first instance of prosecutors rendering posthumous justice to a wrongfully convicted defendant. Chu Ching-en (諸慶恩) — formerly a manager at the Taipei branch of BNP Paribas — was in 1999 accused by Weng Mao-chung (翁茂鍾), then-president of Chia Her Industrial Co, of forging a request for a fixed deposit of US$10 million by I-Hwa Industrial Co, a subsidiary of Chia Her, which was used as collateral. Chu was ruled not guilty in the first trial, but was found guilty
A wild live dugong was found in Taiwan for the first time in 88 years, after it was accidentally caught by a fisher’s net on Tuesday in Yilan County’s Fenniaolin (粉鳥林). This is the first sighting of the species in Taiwan since 1937, having already been considered “extinct” in the country and considered as “vulnerable” by the International Union for Conservation of Nature. A fisher surnamed Chen (陳) went to Fenniaolin to collect the fish in his netting, but instead caught a 3m long, 500kg dugong. The fisher released the animal back into the wild, not realizing it was an endangered species at
DEADLOCK: As the commission is unable to forum a quorum to review license renewal applications, the channel operators are not at fault and can air past their license date The National Communications Commission (NCC) yesterday said that the Public Television Service (PTS) and 36 other television and radio broadcasters could continue airing, despite the commission’s inability to meet a quorum to review their license renewal applications. The licenses of PTS and the other channels are set to expire between this month and June. The National Communications Commission Organization Act (國家通訊傳播委員會組織法) stipulates that the commission must meet the mandated quorum of four to hold a valid meeting. The seven-member commission currently has only three commissioners. “We have informed the channel operators of the progress we have made in reviewing their license renewal applications, and
