Abstract
Experiments were conducted in summer/fall and winter/spring of 1990/91 to determine any potential effects on red swamp crayfish (Procambarus clarkii) resulting from the introduction of Australian red claw crayfish (Cherax quadricarinatus). General health of the animals was monitored throughout the summer/fall experiment using external parasites and haemolymph microbial flora as health indicators. No significant disease outbreaks occurred. Seasonal aspects of production such as temperature tolerance were also gathered from this study. Red claw grew well from May through October, but did not survive the winter. Red swamp crayfish did well only during the cooler months. No negative interactions on native red swamp crayfish were observed.
