Etymology: Ambloplites: Greek, ambloo = blunt + Greek, oplites = shield (Ref. 45335); rupestris: Ambloplites=blunt armature; rupestris=living among the rocks (Ref. 79012). More on author: Rafinesque.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal; pH range: ? - 7.0; dH range: 10 - ?. Temperate; 10°C - 29°C (Ref. 12741); 54°N - 34°N
North America: St. Lawrence River-Great Lakes, Hudson Bay (Red River), and Mississippi River basins from Quebec to Saskatchewan in Canada, and south to northern Georgia, northern Alabama and Missouri (native only to Meramec River) in the USA (Ref. 5723). Introduced to Europe (Ref. 59043).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 43.0 cm TL male/unsexed; (Ref. 5723); common length : 15.4 cm TL male/unsexed; (Ref. 12193); max. published weight: 1.4 kg (Ref. 4699); max. reported age: 18 years (Ref. 72462)
Adults inhabit vegetated and brushy stream margins and pools of creeks and small to medium rivers, and rocky and vegetated margins of lakes (Ref. 5723). Most commonly found in clear, silt-free rocky streams (Ref. 5723). They feed on small crustaceans, insects and fish (Ref. 30578). An introduced species in Europe which avoids swift waters and occurs in a wide variety of slow-flowing to stagnant waters such as large rivers, lakes, ponds, canals and backwaters (Ref. 59043).
The males care about the eggs for about 14 days (Ref. 93240) as well as the young (Ref. 2060). In Europe where it is introduced, males fan and defend the nests, which are shallow depressions in sand or gravel bottom along shallow shores. A male may spawn with several females in one nest and guard the nest until larvae leave the nest (Ref. 59043).
