Aquatic Species at Risk_Spotted

This fish is a medium-sized catostomid (sucker) averaging between 230 and 380 mm in length. The dorsal surface is brown to dark green, the sides silver to bronze and the ventral surface white and silvery. Spotted suckers are distinguished from other catostomid species by the presence of 8-12 parallel rows of dark spots on the base of the scales. The Spotted Sucker avoids currents, living in pools of small streams and overflow ponds in the floodplains of rivers. The pools occupied usually have firm bottoms and aquatic vegetation or other plant debris. They seem to require clear, relatively soft water. This fish spawns in late spring or summer and feeds mainly on small insects and crustaceans.
