Blackchin Shiner
Notropis heterodon (Cope, 1865)
Ray-finned Fishes

Habitat [-]
Blackchin shiners can be found in cool, clear, and shallow sections of lakes and slow regions of streams with weedy vegetation, very little siltation, and a sandy substrate (Smith 1985; Page and Burr 1991).

Associated Ecological Communities [-]
  • Deepwater river
    The aquatic community of very large, very deep, quiet, base level sections of streams with a very low gradient. In places the water is deep enough so that light cannot reach the river bottom.
  • Great Lakes aquatic bed
    The aquatic community of the protected shoals of the Great Lakes or Lake Champlain. They occur in quiet bays that are protected from extreme wave action by islands, shoals, or barrier bars, and typically support large areas of "weeds" or aquatic macrophytes.
  • Marsh headwater stream
    The aquatic community of a small, marshy perennial brook with a very low gradient, slow flow rate, and cool to warm water that flows through a marsh, fen, or swamp where a stream system originates. These streams usually have clearly distinguished meanders (i.e., high sinuosity) and are in unconfined landscapes.
  • Mesotrophic dimictic lake*
    The aquatic community of a lake that is intermediate between an oligotrophic lake and a eutrophic lake. These lakes are dimictic: they have two periods of mixing or turnover (spring and fall); they are thermally stratified in the summer, and they freeze over and become inversely stratified in the winter.

    * probable association but not confirmed
  • Oligotrophic dimictic lake*
    The aquatic community of a nutrient-poor lake that typically occurs in a deep, steeply-banked basin. These lakes are dimictic: they have two periods of mixing or turnover (spring and fall), they are thermally stratified in the summer, and they freeze over and become inversely stratified in the winter.
