Ecology Summary - Gadopsis bispinosus

言語:

主な参照	Allen, G.R., S.H. Midgley and M. Allen, 2002
意見	Occurs in cool, clear streams with rocky bottoms in mountain terrain (Ref. 33616); with fast to moderate flow (Ref. 44894). Often abundant at altitudes of 200-700 m (Ref. 33616). Benthic, nocturnally active species which usually occurs solitary. Juveniles often found in large groups among leaf litter and wood debris. Movements are restricted to a relatively small stretch of river over the duration of the life span. Occurs with G. marmoratus at lower elevations, but they have different habitat preferences. Feeds on insect larvae, fishes, fish eggs, earthworms and crustaceans.
