	<dc:description>Adults occur in lakes, deep flowing pools of creeks, and rivers (Ref. 5723).  Usually found over sand (Ref. 5723).  They move into the shallows of lakes at night  to feed and moves back to deeper water as dawn approaches (Ref. 1998).  They feed on insect larvae, amphipods and fishes (Ref. 1998).  Important forage fish (Ref. 1998).</dc:description>

	<dc:description>Spawning adults move inshore to shallow water or into shallow tributaries of lakes (Ref. 10348). Two or more males cluster with a single female near the surface. They press close to the female, often breaking the surface of the water, and eggs and milt are released (Ref. 27547). Some populations spawn exclusively at night (Ref. 10348), but others show no variation from daytime spawning (Ref. 10349). There is often, perhaps usually, heavy postspawning mortality (Ref. 27547).</dc:description>

	<dc:description>Occurs in lakes, deep flowing pools of creeks, and rivers (Ref. 5723).  Usually found over sand (Ref. 5723).  Moves into the shallows of lakes at night  to feed and moves back to deeper water as dawn approaches (Ref. 1998).  Feeds on insect larvae, amphipods and fishes (Ref. 1998).</dc:description>
