This study tested the oxygen consumption rates (OCR), energy, and thermal coefficient of juvenile Lutjanus malabaricus (60 fish, size: 4.53 +/- 1.14 g) at four temperatures of 22, 26, 30 and 34 degrees C. During 30 days of experimental period 5 fish tank(-1) were reared at four temperatures with three replicates in intermittent flow respirometers in a recirculatory system under laboratory conditions. As expected, oxygen consumption rates increased significantly (P < 0.05) from 1.39 +/- 0.07 to 3.11 +/- 0.09 ml O-2 h(-1) with an increase in the exposed temperature from 22 to 34 degrees C. The corresponding respired energy values also increased from 27.59 +/- 1.03 to 61.78 +/- 0.66 Jh(-1) at 22 and 34 degrees C respectively. The maximum and minimum temperature quotients (Q(10)) were observed between 22-26 degrees C (2.02) and 26-30 degrees C (1.82) respectively. Final preferred temperature (thermal coefficient) estimated between 26 and 30 degrees C. This bioengineering information can be used for designing and sizing a rearing facility for the intensive culture of L. malabaricus.
