Endangered Formosan landlocked salmon natural offspring found

People recently saw a group of newly hatched Formosan landlocked salmon in the Qijiawan River, showing that the species is now naturally reproducing and has overcome the threat of extinction. This endangered species is endemic to Taiwan and its population had dwindled to just over 200 in the 1980s. Years of conservation efforts by public and private agencies have helped the fish rebound.

Formosan landlocked salmon begin hatching in November. They rise to the surface after about 90 days at around 10 degrees Celsius, so these fish look to be about two months old.
These treasured baby fish were seen in February. The Taiwan Salmon Eco Center said it has waited a long time for this moment, as the species was on the verge of extinction with a population of only 200 in the 1980s. Over the past 30 years, the Shei-Pa National Park has restored habitats and released fish fry, helping the population to recover.

In addition to maintaining a core population in the Qijiawan River, our restoration efforts have covered the Hehuan, Nanhu, and other rivers. Over the past five years the population has been over 15,000, reducing the risk of extinction. But facing climate change, typhoons, and drought, I think we need to work more to create additional habitats for them across these rivers.
The baby Formosan landlocked salmon found in the Qijiawan River prove that the fish can naturally reproduce and is no longer in danger of extinction. But as climate change and human activity continues to threaten habitats, conservation requires ongoing efforts.

珍貴! 七家灣溪驚見台灣國寶 "櫻花鉤吻鮭寶寶"現蹤
2026-04-06
有台灣國寶魚之稱的"櫻花鉤吻鮭"，1980年代曾經銳減到只剩200多尾，瀕臨絕種，相關單位多年來致力於復育工作，今年傳出好消息，有民眾在七家灣溪拍到，一群剛出生不久的鮭魚寶寶，這也顯示櫻花鉤吻鮭，能夠自行健康繁殖，擺脫滅絕危機。
一群通體灰色的小魚，隨著水流，有活力的游來游去，在寬廣的溪流裡，看起來不太起眼的牠們，可是有台灣國寶魚之稱的，櫻花鉤吻鮭。

“櫻花鉤吻鮭整個孵化是11月開始，牠應該是經過10度C，大概90天能夠上浮，所以年齡看起來就是兩個月大左右。”
今年2月有民眾在水溫不到10度的七家灣溪，拍到這群剛出生不久的鮭魚寶寶，畫面非常難得，也是櫻花鉤吻鮭復育中心等待好久的時刻，因為1980年代，櫻花鉤吻鮭在七家灣溪只剩下200多尾，為了防止滅絕，雪霸國家公園展開保育行動，這30年來除了復育棲地，也在適合的溪流放流魚苗。

“除了穩住基本盤七家灣溪之外，我們復育整個歷史的溪流，包含合歡溪，包含其他的，像南湖溪等等，這5年來數字都是超過1萬5000尾左右，滅絕危機稍微減少，但面對氣候的變遷，跟整個颱風還有乾旱的因素，我覺得我們必須再深入各個溪流，去創造更多讓牠活存下來的空間。”
這次在七家灣溪拍到的珍貴畫面，顯示櫻花鉤吻鮭能夠健康自行繁衍，不需要人工放流，已經擺脫滅絕危機，不過環境復育以及氣候變遷，也是未來要持續關注的重點。
