Enhancement and monitoring of the Procambarus clarkii population in Lake Mead

Procambarus clarkii are found in extremely low numbers throughout Lake Mead, AZ-NV. The crayfish are an important dietary component for game fish. Enhancement of the crayfish population would broaden the fishery forage base. Crayfish were stocked and monitored in a study cove on Saddle Island to determine if the Procambarus clarkii population could be enhanced. A trapping survey of the area after the following reproductive season yielded low numbers of crayfish. A comparison of pre-stocking and post-stocking catch per trap day (CPTD) values revealed no significant increase in the population. Procambarus clarkii population growth is limited by environmental factors in Lake Mead. If management plans indicate that a large crayfish population is needed for the Lake Mead fishery, stocking of Orconectes virilis is recommended.
