Document Summary
The mean oxygen consumption was collected for both the cold and warm acclimated. The warm acclimated (3-5 c) crayfish mean for oxygen consumption was 5. 28 g o2 min-1g-1, while the cold acclimated (20-25 c) crayfish mean for oxygen consumption was 4. 36 g o2 min-1g-1. The q10 of the experiment was found to be 1. 14. The oxygen consumption values found for the time 0-30 minutes were omitted, as they did not provide an accurate depiction of the results. There are no significant differences between the mean oxygen consumption of warm versus cold acclimated, which demonstrates that compensation has occurred (two tailed unpaired test t69=1. 99, p=0. 107 > 0. 05; figure 1). Figure 1: mean oxygen consumption ( sem) of temperature acclimated crayfish with time interval 30-60 minutes. Cold acclimated and warm acclimated orconectes propinquus both have very similar oxygen consumption rates (figure 1). This demonstrates that crayfish show compensation, and temperature acclimation does not have a great effect on crayfish oxygen consumption.
