What does the black redhorse fish eat?

The black redhorse (Moxostoma duquesnei) is a type of suckermouth catfish. Like other suckermouth catfish, they are bottom feeders and primarily eat insects, crustaceans, mollusks, worms, and plant matter.

Here's a more specific breakdown of their diet:

* Insects: Larvae, nymphs, and adult insects that live on the bottom of rivers and streams.

* Crustaceans: Small crustaceans like crayfish, shrimp, and amphipods.

* Mollusks: Snails and clams, which they use their powerful mouths to crush.

* Worms: Earthworms, aquatic worms, and other invertebrates.

* Plant matter: Algae, detritus, and decaying plant material.

Black redhorse are important for keeping the river bottom clean by consuming dead organic matter and controlling populations of invertebrates. They are opportunistic feeders and will adapt their diet to what's available in their environment.
