Abstract

Temperature is the most prominent factor that influence metabolic rate of aquatic animals. In general, the increasing temperature of 10 degrees Celsius will improve metabolic rate two-fold. Therefore, this research aim is to examine the metabolic rate and Q10 value of crayfish. The metabolic rate of crayfish (Cherax quadricarinatus) was examined by determining oxygen consumption rates using caulorimetric respirometer. The oxygen consumption rates of Cherax quadricarinatus which acclimated at 23_C and 31_C is at around 0.52 and 0.7 uL/g/min respectively. Furthermore, the Q10 value of crayfish between 23_C and 31_C is 1.47. The oxygen consumption and Q10 value of crayfish is different compare with other aquatic invertebrate and ectotherms.

Abstract

Fish from different species have different way to deal with their lifestyle and habitat. From four species that have been researched, Pseudocaranx dentex and Scomberomorus munroi have higher proportion of red muscle, higher relative gill and higher ventricular mass also their muscle have higher buffering capacity than Lethrinus miniatus and Lutjanus erythropterus. It also has been found that white muscle has better ability to handle acid than red muscle. The red muscle are involved in the aerobic slow swimming, while the white muscle have role in faster or burst swimming (anaerobic energy pathway). Therefore, Lethrinus miniatus and Lutjanus erythropterus are less active fish than Pseudocaranx dentex and Scomberomorus munroi.
