Eastern Blacknose Dace (Rhinichthys atratulus)
Along with the longnose dace (R. cataractae), blacknose dace are one of the most common stream fishes found throughout the state of New York. These fish are small (2-3 inches), and are generally found within small streams and lake tributaries. The longnose dace sometimes is found living in turbulent waters. From late spring to early summer, dace spawn in riffles over gravel and rubble where both the male and female construct a nest of small pebbles. After spawning, little parental care is given the eggs.
Dace feed on all types of aquatic insect larvae, worms, and algae.
