Abstract
    Rates of oxygen consumption and filtration by M. edulis increased immediately following feeding. Filtration rates then declined to pre- feeding values within 8-16h. When the food was Tetraselmis suecica, oxygen consumption declined non-linearly to the pre-feeding level within 28- 32h. This decline in oxygen consumption was resolved into 2 components, the first of which was coincident in time with changes in filtration rate, the 2nd of which coincided with a marked increase in rats of ammonia excretion. It is concluded that the first component in oxygen consumption decline represents the mechanical cost of feeding, and amounts to 24% of the energy available in the ingested ration; the 2nd component represents the specific dynamic action of the ration (or the physiological cost of feeding) and amounts to 4% of the energy in the ingested ration. When the food was Phaeodactylum tricornutum, there was no detectable specific dynamic action.
