生態学の Cottus asper

主な参照	Brown, L.R., S.A. Matern and P.B. Moyle, 1995
意見	There appears to be two genetically distinct forms (Ref. 27547), an inland form found in sandy and rocky shores of lakes, and a coastal form usually found over sand in quiet runs of small to medium rivers; sometimes in salt water near river mouths (Ref. 2850). The coastal form moves into brackish estuaries to spawn (Ref. 27547). Feed mainly on aquatic insect larvae and bottom invertebrates (Ref. 1998). Juvenile and adults feed mainly on insects (Ref. 13348).
