簡短描述
檢索表 | 型態特徵 | 形態測量圖
Differs from the sympatric, non-anadromous Salvelinus salvelinus population by having the following unique characters: maximum size 17 cm SL; spawns for the first time at 11.0 cm SL (vs. 28 cm SL); and mature individuals with belly drab bronze greyish (vs. bright yellow to carmine). Can be further diagnosed by having 30-42 pyloric caeca (vs. 39-52); 22-26 gill rakers (vs. 24-27);and mature individuals often with parr marks (vs. absence) (Ref. 59043).
A non-anadromous species which inhabits shallow lakes. Feeds on benthic invertebrates (Ref. 59043).
