Document Summary
Effects of acclimation temperature on oxygen consumption in the crayfish, orconectes propinquus. The mean of oxygen consumption level was collected for both warm and cold acclimated crayfish, orconectes propinquus. The crayfish acclimated to the warm treatment (20-25 c) had a mean o2 consumption rate of 3. 55 g o2 min-1g-1. 5 c) had a mean for o2 consumption rate of 3. 64 g o2 min-1g-1. As shown in figure 1, there is no significant difference between the oxygen consumption mean of warm acclimated crayfish and cold acclimated crayfish. The q10 value for o2 consumption was 0. 946. Figure 1: mean oxygen consumption ( sem) of changing temperature (cold, 5oc; warm, Despite the difference in acclimation temperatures, both warm and cold acclimated crayfish: propinquus had a very similar mean oxygen consumption rates (figure 1). This proves that the crayfish showed a metabolic compensation response to changes in temperature.
