In the present study, we observed high ADC values for all test ingredients and corresponding diets, reflecting the ability of adult redclaw to utilize a wide range of nutrient sources. High digestibility coefficients for a wide variety of animal and plant-based ingredients are not unusual in freshwater crayfish, as observed in juvenile redclaw (Campana-Torres et al., 2005), red swamp crayfish (Procambarus clarkii) ( Reigh et al., 1990) and yabby (Cherax destructor) ( Jones and De Silva, 1997).
