Researcher holding a crayfish collected in Diablo Lake
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.
