A Tainan-based aquaculture company has developed a system that uses 5G networks to prevent mass fish deaths during cold snaps.
Yen Jung-hung (顏榮宏), the founder of Fisherman Taijiang, said rapid drops in temperature stymie algae growth in fish ponds.
The clear surface makes it more difficult to increase the water temperature, leading to mass fish deaths, Yen said.

The system shines blue and green lights on the ponds to help promote algae growth, which helps retain heat in the pond, while the fish, shrimps and other creatures feel “safer,” he said.
Water temperature in a pond increases 1°C for every 30cm in depth, Yen said.
If the surface temperature is 12°C in a pond that is 150cm deep, then the temperature at the bottom would be 17°C, if the bottom is free of sediment, he said.
Yen cautioned fish farmers against making sudden changes to their ponds and entering the pond frequently.
The lighting system could be used by fish farmers to remotely monitor their ponds, and it allows fish farmers to remotely activate equipment such as pumps and water wheels, he said.
The system allows real-time monitoring, allowing pond owners to remotely surveil their property, eliminating the need to frequently enter the ponds, which only disturbs the creatures raised in them, Yen said.
Yen said he has a master’s degree in biotechnology, and has used his knowledge and skills to innovate his family’s aquafarming business.
Fisherman Taijiang serves as a platform where local fish farmers and collaborating university teams can interact.
It also serves as a sales platform for fish and other products raised by local aquafarmers.
The Fisheries Agency yesterday issued a warning for fish farmers over a new cold front approaching the nation, urging them to take precautions to protect their ponds.
TOO CLOSE FOR COMFORT: A US Air Force KC-135 tanker came less than 1,000 feet of an EVA plane and was warned off by a Taipei air traffic controller, a report said A US aerial refueling aircraft came very close to an EVA Airways jet in the airspace over southern Taiwan, a military aviation news Web site said. A report published by Alert 5 on Tuesday said that automatic dependent surveillance–broadcast (ADS-B) data captured by planfinder.net on Wednesday last week showed a US Air Force KC-135 tanker “coming less than 1,000 feet [305m] vertically with EVA Air flight BR225 as both aircraft crossed path south of Taiwan” that morning. The report included an audio recording of a female controller from the Taipei air traffic control center telling the unidentified aircraft that it was
A US aircraft carrier group led by the USS Theodore Roosevelt has entered the South China Sea to promote “freedom of the seas,” the US military said yesterday, as tensions between China and Taiwan raise concerns in Washington. US Indo-Pacific Command said in a statement that the strike group entered the South China Sea on Saturday, the same day Taiwan reported a large incursion of Chinese bombers and fighter jets into its air defense identification zone near the Pratas Islands (Dongsha Islands, 東沙群島). The US military said the carrier strike group was in the South China Sea, a large part of which
STRATEGIC MISTAKE: Beijing’s deployment of aircraft near Taiwan proves the ‘China threat theory’ that sees it attempting to destabilize the region, an analyst said China on Saturday and yesterday sent a record number of military aircraft into the nation’s air defense identification zone (ADIZ), in what analysts said was an attempt to flex its military might for US President Joe Biden. Thirteen Chinese warplanes flew into Taiwan’s southwestern ADIZ on Saturday and 15 entered yesterday, the highest number observed in a single day this year, the Ministry of National Defense said. On Saturday, eight Xian H-6K bombers, four Shenyang J-16 fighters and a Y-8 anti-submarine aircraft, entered the ADIZ, while yesterday there were two Y-8s, two Su-30s, four J-16s, six J-10 fighters and a Y-8 reconnaissance
DISPOSING MYTHS: A new constitution would better reflect reality, as the current one was drafted ‘in and for China,’ without the consent of Taiwanese, advocates said Independence advocates yesterday launched the Taiwan New Constitution Alliance to promote drafting a new, localized constitution. “This is a historic moment for Taiwan. Drafting a new constitution is the most important task Taiwanese face,” veteran independence advocate Koo Kwang-ming (辜寬敏) said at the inaugural event in Taipei. “Although the Democratic Progressive Party is in power, its authority is based on the Republic of China [ROC] Constitution, which has no connection to Taiwan,” said the 95-year-old Koo, a former presidential adviser. “The historic task of drafting a new constitution depends on efforts by all Taiwanese,” Koo said. “A constitution for a sovereign, independent Taiwan
