Summary
Ecologically, the California freshwater shrimp occupy a role as detritus feeders that no other stream animal could fill. When you rip an important strand out of a food web, there’s no way to know how much damage will be done. The shrimp’s presence, or absence, can also tell us a lot about the streams. Flowing water is their home, and they are mute witnesses to the condition and history of the streams they inhabit. Continually bathed by the water, they must face whatever flows toward them. Pollution, siltation, introduced species, and other factors will all affect them to some extent. If they disappear, we can be sure that something detrimental has happened to the stream. We will have lost much more than just the shrimp.
