✦ Synopsis

Laboratory measurements of oxygen consumption were made on Penaeus monodon (Fabricius) from protozoea to adult stage at temperatures between 15 ~ and 35~ The logarithmic relationship between weight-specific respiration rate (WRt) and temperature (T) for two size groups, Protozoea 1 (PZ1) to Postlarva 1 (PL1) and PL to adult, are given as; WRt--IO ~162176176

(ml 0 2 g-1 h-i) and

WRt=IO -~176176

(ml 02 g-1 h-i), respectively. Additionally, equations relating metabolic rate, temperature and size for the two size groups are; PZ1-PLI: log M=0.431 +0.0146T+(1.25 (log TL)+0.579), and PL1adult: log M = -0.948 + 0.0338 T+ (2.60 (log CL) -0.683), where M= oxygen consumption in ml O 2 individual -1 h-l, T= temperature in ~ TL=total length in cm, and CL=carapace length in cm. Activation energies of 6 186.75 J for PZ1 -PLI and 14 066.62 J for PL-adults point to different metabolic pathways or to differences in the ratio between the metabolic pathways used.
