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 °C. During 30 days of experimental period 5 fish tank 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 h with an increase in the exposed temperature from 22 to 34 °C. The corresponding respired energy values also increased from 27.59 ± 1.03 to 61.78 ± 0.66 Jh at 22 and 34 °C respectively. The maximum and minimum temperature quotients (Q) were observed between 22-26 °C (2.02) and 26-30 °C (1.82) respectively. Final preferred temperature (thermal coefficient) estimated between 26 and 30 °C. This bioengineering information can be used for designing and sizing a rearing facility for the intensive culture of L. malabaricus.
