BIOECONOMIC MANAGEMENT OF RED SWAMP CRAYFISH (PROCAMBARUS CLARKII) IN THE PRESENCE OF ENVIRONMENTAL EXTERNALITIES [PDF]
Red swamp crayfish (Procambarus clarkii) is a valuable renewable resource which creates significant negative externalities to its environment. Crayfish can cause severe crop damage by burrowing in fields and using irrigation systems to spread.

SPERMIOGENESIS IN THE CRAYFISH (PROCAMBARUS CLARKII) [PDF]
The Journal of Cell Biology, 1961 The sperm of the crayfish, Procambarus clarkii, is relatively simple among decapod sperm and was described in the first paper of this series (28). The present paper details the development of this sperm as followed with the light and electron microscopes. The process is divided into six stages for purposes of description.
