Emerald Shiner (Notropis atherinoides)

Description: 

The Emerald Shiner is a wide-ranging species found in Gulf Coast drainages from Texas to Alabama, including the Mobile Basin, the Mississippi River Drainage, including the Tennessee, and Cumberland river drainages, and Great Lakes-St. Lawrence and Arctic River drainages to northern Canada. They are found in pools and runs of medium to large rivers and in lakes. As the common name suggests, Emerald Shiners have a silver stripe along their side that reflects an iridescent blue-green color.
