The majority of Taiwan’s long-distance saury fishing vessels have switched to LEDs for environmental reasons, the Kaohsiung City Government’s Marine Bureau said on Tuesday.
The methods fishers use to catch squid or saury are similar, the bureau said.
Some boats travel to the Southwest Atlantic to fish for squid in the first half of the year, return and then venture out again to fish for saury in the north Pacific in the months following, it said.

Fishing for saury happens at night, with artificial light playing an important role in attracting them, the bureau said.
In the past, fishers often used incandescent light bulbs or high-intensity discharge (HID) lamps, but they tend to consume a lot of energy, the bureau said.
Incandescent bulbs and HIDs also wear out faster and must be replaced more often than LEDs, so most operators have since switched to LEDs, which last longer and use less power.
Saury fishing boats that are registered in Kaohsiung have since the end of last month been returning to Cianjhen Fishing Port (前鎮漁港) from north of the Pacific Ocean, the bureau said.
Taiwan’s total saury catch in 2021 was about 30,000 tonnes, while last year it was about 40,000 tonnes, a Fisheries Agency news release said in March.
Citing the North Pacific Fisheries Commission, the agency said that about 90 long-distance Taiwanese saury vessels operate in the northwest Pacific every year from June to November.

BITTERLY COLD: The inauguration ceremony for US president-elect Donald Trump has been moved indoors due to cold weather, with the new venue lacking capacity A delegation of cross-party lawmakers from Taiwan, led by Legislative Speaker Han Kuo-yu (韓國瑜), for the inauguration of US president-elect Donald Trump, would not be able to attend the ceremony, as it is being moved indoors due to forecasts of intense cold weather in Washington tomorrow.

Another wave of cold air would affect Taiwan starting from Friday and could evolve into a continental cold mass, the Central Weather Administration (CWA) said yesterday. Temperatures could drop below 10°C across Taiwan on Monday and Tuesday next week, CWA forecaster Chang Chun-yao (張竣堯) said. Seasonal northeasterly winds could bring rain, he said.
