Stock of 24 common fish species around Taiwan are declining due to overfishing, while the average size of the fish in catches is shrinking, Greenpeace said on Thursday as it announced the results of its “fish census” at a news conference in Taipei.
The study — which assessed fresh catches at harbors and markets across Taiwan — showed that the nation’s marine resources are in urgent need of protection, Greenpeace said.
Its staff collaborated with National Kaohsiung University of Science and Technology aquaculture researcher Ho Hsuan-ching (何宣慶) to conduct the study, which focused on 40 common fish species as they were offloaded or put on sale, Greenpeace project manager Lee Yu-tong (李于彤) said.

The study showed a large decline in the proportion of mature fish in catches, indicating a serious overfishing problem for all 24 species, Lee said.
“Most of the 24 species are fish commonly consumed by Taiwanese, including greater amberjack, dory, Japanese jack mackerel, silver pomfret, red tilefish and black croaker,” she said.
“The study showed that over-fishing has placed a lot of stress on the species so that they are unable to sustain their populations,” she said.
In the long term, Taiwan’s main economic fish stocks would decline and the average fish size would shrink, harming the livelihoods of local communities, she said, adding that “it would be a lose-lose situation for fishers and the marine ecosystem.”
The study was conducted from March last year to January at Donggang (東港) in Pingtung County, Cianjhen (前鎮) and Keziliao (蚵仔寮) in Kaohsiung, Magong (馬公) in Penghu County, and Dashi (大溪) and Nanfangao (南方澳) in Yilan County.
About 30,000 samples were measured, Lee said.
The data showed that for five species — silver pomfret, greater amberjack, black croaker, javelin grunte and silver grunt — more than 90 percent of the fish measured were under their respective lengths at maturity, Ho said.
It was the first widely conducted fish census for Taiwan, he said.
“The results showed a high proportion of immature, small fishes, which is the same issue fishers around the world are facing,” he said. “If we can sound the alarm early, maybe can come up with a strategy to make changes.”
“When fish stocks are depleted, seafood prices will rise,” Ho said. “If we continue with the ways we catch and consume fish, all of the species will be eaten into extinction.”
Shao Kuang-chao (邵廣昭), an honorary fellow at Academia Sinica’s Biodiversity Research Center, said that lawmakers have approved a draft marine conservation act, but it has been delayed for years at the legislature.
The legislation would allow government agencies to plan for and delineate protected marine areas and impose fines of up to NT$500,000 for those who ignore them, Shao said.
There are many ways to conserve marine resources, but setting up protected areas and properly enforcing them is the simplest, most economical and most effective approach, he added.
Taiwan would benefit from more integrated military strategies and deployments if the US and its allies treat the East China Sea, the Taiwan Strait and the South China Sea as a “single theater of operations,” a Taiwanese military expert said yesterday. Shen Ming-shih (沈明室), a researcher at the Institute for National Defense and Security Research, said he made the assessment after two Japanese military experts warned of emerging threats from China based on a drill conducted this month by the Chinese People’s Liberation Army’s (PLA) Eastern Theater Command. Japan Institute for National Fundamentals researcher Maki Nakagawa said the drill differed from the
‘WORSE THAN COMMUNISTS’: President William Lai has cracked down on his political enemies and has attempted to exterminate all opposition forces, the chairman said The legislature would motion for a presidential recall after May 20, Chinese Nationalist Party (KMT) Chairman Eric Chu (朱立倫) said yesterday at a protest themed “against green communists and dictatorship” in Taipei. Taiwan is supposed to be a peaceful homeland where people are united, but President William Lai (賴清德) has been polarizing and tearing apart society since his inauguration, Chu said. Lai must show his commitment to his job, otherwise a referendum could be initiated to recall him, he said. Democracy means the rule of the people, not the rule of the Democratic Progressive Party (DPP), but Lai has failed to fulfill his
A rally held by opposition parties yesterday demonstrates that Taiwan is a democratic country, President William Lai (賴清德) said yesterday, adding that if opposition parties really want to fight dictatorship, they should fight it on Tiananmen Square in Beijing. The Chinese Nationalist Party (KMT) held a protest with the theme “against green communists and dictatorship,” and was joined by the Taiwan People’s Party. Lai said the opposition parties are against what they called the “green communists,” but do not fight against the “Chinese communists,” adding that if they really want to fight dictatorship, they should go to the right place and face
A 79-year-old woman died today after being struck by a train at a level crossing in Taoyuan, police said. The woman, identified by her surname Wang (王), crossed the tracks even though the barriers were down in Jhongli District’s (中壢) Neili (內壢) area, the Taoyuan Branch of the Railway Police Bureau said. Surveillance footage showed that the railway barriers were lowered when Wang entered the crossing, but why she ventured onto the track remains under investigation, the police said. Police said they received a report of an incident at 6:41am involving local train No. 2133 that was heading from Keelung to Chiayi City. Investigators
