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.
