Abstract: Effects of heavy metal ions, temperature, salinity on the embryonic development of undulated surf clam, Paphia undulate were studied by using the method of experimental ecology, the main results were shown as follows: 1)four kinds of heavy metal ions showed an obvious inhibitory effect on embryos. The four metals were arranged as Cu2+ > Zn2+ > Cd2+ >Pb2+ in order of toxicity, and the EC50 values of four kinds of metal ions were 83.29, 184.32, 230.00, 239.04 ng/mL, respectively; 2) The optimum temperature and salinity for embryonic development were 24~30℃ and 27~33 respectively, while the best ones were 30℃ and 30 respectively. These results would provide a technological basis for the artificial seedling of the undulated surf clam.
