توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
Distinguished from its congeners in British Isles by its unique body depth about 4.6-5.0 times in SL. Differs further by the combination of the following characters: body brown to silvery, black spots small (equal to or smaller than pupil), few or absent; large size; and maxilla reaching beyond posterior margin of eye (Ref. 59043).
Inhabits large oligotrophic lakes. In Scotland, this species occurs usually in lakes inhabited by Salvelinus species on which it preys. Feeds on fishes and a variety of insects. In Scotland, preys on invertebrates until about 30 cm SL, then becomes piscivorous, feeding mostly on Salvelinus species. Spawns only in the larger and deeper tributaries (Ref. 59043).
