M.E. DeMont and R.K. O'Dor. (1984). The effects of activity, temperature and mass on the respiratory metabolism of the squid, Illex illecebrosus. J. Mar. Biol. Ass. U.K. 64, 535-543.


Summary

Oxygen consumption was measured in squid (Illex illecebrosus) ranging from 42.7 to 443.0 g. Ambient temperature increased from 8.3oC to 18.2oC during the experimental period. Resting rates were calculated by correcting for the percentage of time not spent in the resting posture. A 100 g squid resting at 13oC has a predicted oxygen consumption of 31.3 ml/h, while a continuously swimming squid has an oxygen consumption of 125.0 ml/h. Oxygen consumption is almost directly proportional to body size. A 10oC increase in environmental temperature would increase oxygen consumption for a squid of given mass by 6.7 times.
