Ecology center supports Formosan salmon population recovery
2026-04-07
The Formosan landlocked salmon has overcome the threat of extinction thanks in large part to a breeding center at Wuling Farm. This ecological center is divided into three zones and maintains a salmon population of around 10,000. The facility is not open to the public, but FTV go you on an exclusive tour to see how it operates.
Covered in black spots and swimming around the tank, these are Formosan landlocked salmon, an endangered species endemic to Taiwan. This ecological center at the Wuling Farm has played a crucial role in helping the species recover, raising the fish from egg to adult every year starting in November.
Liao Lin-yen
Ecology center director
We raise breeding fish and salmon that are over two years old here. Each tank here has over two tons of water and larger fish survive better here. Behind are areas B and C, which have smaller fish and fertilized eggs.
The facility is split into three areas, each one caring for different sizes of fish. But one fish here stands out for its unique light-colored scaling. This is an albino Formosan salmon.
Chang Chiao-ying
Ecology center researcher
Albinism is actually a sign of reduced genetic diversity, which is the result of inbreeding. To prevent this genetic reduction, we catch wild fish in the upstream part of the Qijiawan River and pair them with fish from the breeding tank.
The center maintains a population of over 10,000 Formosan landlocked salmon, 2,000 of which are released into the wild, while 8,000 are kept for conservation and research. Through breeding and conservation efforts, the center has ensured this endemic fish species will not go extinct.

揭秘! 直擊國寶魚秘密基地 "櫻花鉤吻鮭"對抗滅絕
2026-04-07
櫻花鉤吻鮭擺脫滅種危機，位在武陵農場的復育中心，功勞非常大!這處基地分為三區，有大小不同的魚缸，全區鮭魚數量，始終會保持在1萬尾，不過復育中心不開放民眾參觀，我們現在帶您一探究竟，生態基地內部如何運作。
帶滿黑色斑點，在池裡用力擺動身軀，活力滿滿，櫻花鉤吻鮭已經擺脫滅絕危機，在這漫長復育過程中，位在武陵農場的復育中心，功不可沒，每年11月開始的復育工作，從孵化到成魚都是在這裡。

“這是養種魚跟2歲以上鮭魚在這個地方，這個池子每池大概有2噸多的水，比較大隻的魚可以在這邊活存得比較好，那後面是B區跟C區，比較小隻的魚還有受精卵的區域。”
整個基地分成三個區域，每個區域都有不同大小的鮭魚，不過在這魚群裡，有一條顏色長得不太一樣，原來牠是一隻有白化症的櫻花鉤吻鮭。
[[生態中心復育基地研究助理 張巧穎]]
“白化其實是基因矮化的一個表現，就是近親交配出現的後代，那我們現在為了防止基因矮化，我們都會去野外釣，七家灣溪上游的鮭魚回來，跟種源庫裡面的魚隻做配對。”
復育中心內會一直保持櫻花鉤吻鮭數量，在一萬尾以上來預防滅絕，其中2000尾放流，8000尾保種或是研究用，復育行動，不會中斷，要好好留下這珍貴的台灣國寶魚。
