The effects of water temperature on oxygen consumption rate of the juvenile oval squid
Sepioteuthis lessoniana ranging from 0.04 to 4.28g in body weight were investigated individually by a
water bottle method at 10, 15, 20, 25, and 30°C. Oxygen consumption rate in ml oxygen/indiv./h (R)
increased linearly with increase of body weight in g (W) and was expressed as R=aWb•CT for all temperature conditions (T), where a=0.143, b=0.929, and C=1.069 (n=202). The correlation coefficient
between R and T was 0.993, and Q10 showed 1.95 within the range of 10 and 30°C. The influence of temperature on the oxygen consumption was relatively constant in the young over 0.48g up to 4.28g at temperature levels under the present investigation. However, the effect of temperature upon oxygen consumption rates was larger in the younger squid reared at a temperature higher than 20°C. The
metabolism of squid in the early stages before 0.199g is assumed to be stronglyaffected by the differences of water temperature within the range of 15-25°C.
