Researcher holding a crayfish collected in Diablo Lake
Detailed Description
A native crayfish collected in Diablo Lake for an investigation into food availability for native fish and limitations to their growth. Crayfish are invertebrate prey for salmonids and provide useful representative stable isotope values for benthic members of the food web.
Crayfish can exclude minnows from using interstitial refuges (i.e., rockslides, etc.), thus exposing minnows to more predation risk by salmonids.

WFRC Ecology Section - Projects Overview
The Ecology Section examines how environmental variability, human activities and infrastructure influence food web interactions and species performance in freshwater and marine ecosystems. We have extensive experience in quantifying aquatic food web processes as they relate to growth, survival and production of key species of interest, especially resident and anadromous salmonids.
