Biology     Glossary (e.g. epibenthic)

Inhabits rocky and sandy pools and runs of small to large rivers. Common in clear, warm streams. Voracious minnow with pike-like habits (Ref. 5723). Small pikeminnows (less than or equal to 7 cm SL) are found in shallow water with cover and lower velocities. The microhabitat use of these juveniles is controlled by the presence of large pikeminnows which connotes intraspecific predation. The microhabitat shift is observed to be significantly influenced by the presence rather than the number of large pikeminnows in the area (Ref. 55069).
