抄録

To clarify the effects of the procedures for nuclear insertion on physiological function in the pearl oyster Pinctada fucata martensii, ventilation volume (Vg) and amount of oxygen uptake (Vo2) were measured before and during feeding with the Chaetoceros gracilis in the non-treated group (NTG), the treated group (Sitate sagyou group, TG), artificial spawning by bubbling ozone-gas group (SOG), and operation of nuclear insertion group (ONG). NTG and TG showed more of the same Vg, and SOG and ONG exhibited nearly half of Vg of NTG. TG, SOG and ONG indicated the similar Vo2, which were approximately half of Vo2 of NTG. These results suggested that artificial spawning by bubbling ozone-gas and operation of nuclear insertion does not influence the oxygen uptake, but that the artificial spawning affect the ventilation.
