An Illustrated Id Guide To The Crayfishes Found In Nebraska Native And Non-Native, Steve Schainost
An Illustrated Id Guide To The Crayfishes Found In Nebraska Native And Non-Native, Steve Schainost
Nebraska Invasive Species Program
There are five crayfishes native to Nebraska. These are:
Orconectes immunis (papershell crayfish)
Orconectes virilis (northern crayfish)
Orconectes neglectus neglectus (ringed crayfish)
Cambarus diogenes (Devil crayfish)
Procambarus gracilis (prairie crayfish)
Three additional non-native crayfishes have also been found here:
Orconectes rusticus (rusty crayfish) [bait tanks and established in two ponds in Omaha]
Procambarus clarkii (red swamp crayfish) [bait tanks]
Procambarus acutus (White River crayfish) [bait tanks]
I will attempt here to provide a photographic guide to field identification, one species per page.

Habitat disturbances affect wildlife populations through numerous mechanisms, and determining specific components of habitat disturbances affecting those populations is challenging. For example, a single disturbance can both change local habitat conditions and impose limitations on dispersal of animals. Both of these components can negatively affect biological responses, such as body condition, local movement patterns, or survival. Culverts are a habitat disturbance having both of these components. Culverts affect local habitat conditions by increasing sediment levels in downstream reaches, negatively affecting animals downstream of culverts. Culverts also impose limits on dispersal by blocking passage of stream organisms to upstream reaches, negatively …
