In order to investigate the optimal environment factor for growth of the cockle shell, Anadara granosa bisenensis, tolerance experiment to the water temperature and salinity have been conducted. In the tolerance experiment to the temperature A. granosa bisenensis survived a very wide range from 3℃ to 33℃, but their survival rate was lower at higher water temperature up to 35℃. In the case of salinity their tolerance range was from 0‰ to 100‰ and showed higher survival rate at lower salinity. Growth in shell length and total weight of the spat at the end of the rearing experiment was 13.17±0.98 mm and 0.69±011 g.
