Abstract
    1. The energy contributions of aerobic metabolism, phosphoarginine, ATP and octopine in the adductor muscles of P. magellanicus were examined during swimming and recovery.2. A linear relationship was observed between the size of the phosphoarginine pool and the number of valve snaps. A linear increase in arginine occurred during the same period.3. Octopine was formed during the first few hours of recovery, particularly in the phasic muscle.4. The restoration of the phosphoarginine pool appeared to be by aerobic metabolism.5. It is concluded that the role of octopine formation is to supply energy when the tissues are anoxic and to operate at such a rate as to maintain the basal rate of energy production.
