  • Title: Oxygen consumption and pumping rates in the hard clam Mercenaria mercenaria: a direct method.
    Author: Hamwi A, Haskin HH.
    Journal: Science; 1969 Feb 21; 163(3869):823-4. PubMed ID: 5764478.
    Abstract:
    Respiratory and pumping rates in the hard clam Mercenaria mercenaria were measured directly in running seawater; the quiatntity of oxygen used was calculated from the difference in concentrations in incurrent and excurrent water. A linear relationship between pumping and respiratory rates suggests regulation of water transport by, oxygen requirement rather than by feeding.
