Abstract

  • 1.

    1. During the decline of oxygen tension Mytilus edulis either regulated (regulators) or failed to regulate (conformers) oxygen consumption.

  • 2.

    2. Ventilation rate, and the frequency and amplitude of heat beat, increased at slightly reduced oxygen tension.

  • 3.

    3. At low pO2 ventilation rate and heart frequency declined, with increased amplitude of heart beat.

  • 4.

    4. The ventilation: relative perfusion ratio decreased with declining pO2 in regulators but remained constant in conformers.

  • 5.

    5. It is suggested that regulation of oxygen consumption at reduced oxygen tension is based on control of the ventilation: perfusion ratio.
