Habitat Suitability Criteria for Native Fishes in Intermediate-Sized Arizona Rivers

Duration

June 2016 - December 2018

Narrative

The native fish populations of the southwestern United States are highly endangered and drastically declining due to multiple anthropogenic stressors. In order to manage these populations, information about the microhabitat the fishes occupy is needed. Physical habitat has been defined for several native species in Arizona through habitat suitability criteria (HSC), yet this can vary among streams and or fishes can inhabit different microhabitat due to presence of other species. It is critical to develop HSC for native fish species across multiple rivers to better understand how the distribution is formed under various circumstances. Four streams within central Arizona (Verde River, Blue River, San Francisco River, Tonto Creek) have been selected based on high priority in which to develop generalized habitat criteria. Prepositioned areal electrofishing devices (PAEDs) will be used to sample fishes in randomly selected sites within each stream. Depth, substrate, and flow will also be measured at each site. Habitat suitability criteria will be developed for species found within these streams. Field work on this project will commence spring, 2017. Information will be presented in a publication and thesis.
