Eco-Photo of the Formosan Landlocked Salmon (Oncorhynchus formosanus) 臺灣鈎吻鮭

Formosan landlocked salmon can be found on the upstream of the Dajia River which has an elevation level of above 1500m. They are temperate cold-water fish that have remained in the high mountain streams since the ice age, and can only survive in streams with temperatures of under 15˚. Food sources include aquatic insects and other insects that have fallen into the water. They are about 20 to 30cm in body length; the sides are flat, the backsblack-green and abdomen silvery white. There are nine oval-shaped spots on the center of the sides of the body.
