Feeding raises the metabolic rate of Octopus vulgaris. The increase in oxygen consumption has two distinct components. There is a progressive increase in routine uptake over the first three or four days of feeding following a period of starvation, which can end by doubling or trebling the standard metabolic rate; the effect is most marked in small animals. Superimposed on this rise in baseline there is a short-term rise and fall, with a timescale of 6 hours or so, following each meal. The short-term cost of assimilating crab flesh is in the region of 9 ml O2 g-1. Taken togeather and compared with the standard rate, and the cost of locomotion in search of prey, the short and long-term increases that follow feeding mean that feeding state is overwhelmingly the most important determinant of the daily energy requirement of Octopus. |
