National Penghu University has successfully cultivated cuttlefish in a fully controlled environment -- an achievement that could help stop cuttlefish dwindling in the wild.
"The birth of the cuttlefish in an artificially controlled environment is the first program of its kind in Taiwan," Wong Chin-ping (
Wong said the research team successfully cultivated 1,500 cuttlefish last spring from 2,000 eggs collected in the wild. One hundred of those were raised in a tank at a laboratory and were fed shrimp.
The cuttlefish grew rapidly to weigh 500g to 800g at nine months old, Wong said. They later laid eggs, producing around 1,000 cuttlefish of 1cm to 3cm in size. Around 500 of them died before reaching maturity.
The project's aim is to enable Taiwan to mass produce cuttlefish, a popular seafood, for consumption. Cuttlefish are usually made into balls, stir fried or added to soup.
However, in recent years, the number of cuttlefish in the wild has dropped sharply. Only a few research teams have been trying to raise them in tanks.
The project is being billed as a great milestone for stimulating the regeneration of cuttlefish stocks and developing marine and aquaculture industries, Wong said.
The mollusc used in the project is the pharaoh cuttlefish. Its normal life expectancy is about one year and it lays approximately 300 to 500 eggs only once in its lifetime, Wong said.
Under "full cultivation" conditions, the survival rate of the cuttlefish species in the project has been 80 percent so far, a rate that is far higher than in the wild, said Hsue Yung-lin (
Hsue said that the cuttlefish grew more quickly in captivity because of the feed provided to them.
Four factors led to the declaration of a typhoon day and the cancelation of classes yesterday, Taipei Mayor Chiang Wan-an (蔣萬安) said. Work and classes were canceled across Taiwan yesterday as Typhoon Krathon was forecast to make landfall in the southern part of the country. However, northern Taiwan had only heavy winds during the day and rain in the evening, leading some to criticize the cancelation. Speaking at a Taipei City Council meeting yesterday, Chiang said the decision was made due to the possibility of landslides and other problems in mountainous areas, the need to avoid a potentially dangerous commute for those
Typhoon Krathon, a military airshow and rehearsals for Double Ten National Day celebrations might disrupt flights at Taiwan Taoyuan International Airport in the first 10 days of next month, the airport’s operator said yesterday. Taoyuan International Airport Corp said in a statement that it has established a response center after the Central Weather Administration issued a sea warning for Krathon, and urged passengers to remain alert to the possibility of disruptions caused by the storm in the coming days. Flight schedules might also change while the air force conducts rehearsals and holds a final airshow for Double Ten National Day, it added. Although
SEMICONDUCTORS: TSMC is able to produce 2-nanometer chips and mass production is expected to be launched by next year, the company said In leading-edge semiconductor manufacturing China is behind Taiwan Semiconductor Manufacturing Co (TSMC) by at least 10 years as the Taiwanese chipmaker’s manufacturing process has progressed to 2 nanometers, National Science and Technology Council (NSTC) Minister Wu Cheng-wen (吳誠文) said yesterday. Wu made the remarks during a meeting of the Legislative Yuan’s Education and Culture Committee when asked by Democratic Progressive Party Legislator Wu Pei-yi (吳沛憶) about a report published in August by the Chinese version of Nikkei Asia that said Taiwan’s lead over China in chip manufacturing was only three years. She asked Wu Cheng-wen if the report was an accurate
PRO-CHINA SLOGANS: Two DPP members criticized police officers’ lack of action at the scene, saying that law enforcement authorities should investigate the incident Chinese tourists allegedly interrupted a protest in Taipei on Tuesday held by Hong Kongers, knocked down several flags and shouted: “Taiwan and Hong Kong belong to China.” Hong Kong democracy activists were holding a demonstration as Tuesday was China’s National Day. A video posted online by civic group Hong Kong Outlanders shows a couple, who are allegedly Chinese, during the demonstration. “Today is China’s National Day, and I won’t allow the displaying of these flags,” the male yells in the video before pushing some demonstrators and knocking down a few flagpoles. Radio Free Asia reported that some of the demonstrators
