Document Summary
Mean oxygen consumption of acclimated crayfish orconectes propinquus in warm (21. 459 c 0. 106) or cold (8. 169 0. 411 c) water. Crayfish in warm water did not have significantly different oxygen consumption (3. 876 0. 241 g o2 min-1g-1) than the crayfish in cold water (3. 820 0. 238 g o2 min-1g-1). The mean oxygen consumption of crayfish acclimated to either warm (21. 459 . 0. 106 c) water or cold (8. 169 0. 411 c) was collected for a total of 77 specimens. All specimens were collected from medway creek and the mass of warm crayfish oronectes propinquus (10. 750 1. 363g) was similar to the mass of crayfish in cold water (12. 978 . At the end of the experiment, it was found that there was no statistically significant difference in oxygen consumption between crayfish acclimated to warm water versus crayfish acclimated to cold water (t154 = 1. 975, p = 0. 868). After collecting the results, we fail to reject the null hypothesis because q10 = 1. 011.
