The acid phosphatase(ACP) and alkaline phosphatase(AKP) in the embryo and early larva of scallop Patinopecten yessoensis were studied by histochemistrical localization.ACP and AKP positive granules were discovered in all stages.The ACP distributed uniformly in oocyte.The distribution of ACP positive granules in fertilized egg varied and the center of fertilized egg presented weakly positive ganucles of ACP.The ACP positive granules in the bigger blastomere were more than the smaller one.The ACQ was mainly displayed near the nuclear zone from 16-cell stage and blastula,and the ACP was mainly detected on mantle and visceral mass in veliger larva.The AKP positive granules were found mainly in the center of oocyte and along the cell membrane.A great deal of AKP positive granules distributed along the cellular membrane in cleavage stage,morula,blastula,gastrula and trochophore.Most of AKP was located on visceral mass and the margin of mantle in veliger larva stage.
