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$^{\circ}C$ to 33$^{\circ}C$, but their survival rate was lower at higher water temperature up to 35$^{\circ}C$. In the case of salinity their tolerance range was from 0$\textperthousand$ to 100$\textperthousand$ 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${\pm}$0.98 mm and 0.69${\pm}$011 g.

The filtration rate and oxygen consumption of Anadara granosa bisenensis were measured at 4 different temperature (10$^{\circ}C$, 15$^{\circ}C$, 20$^{\circ}C$, and 25$^{\circ}C$) and 4 different salinity levels (20, 25, 35, and 40 psu), using an direct method under laboratory conditions. The samples were divided into two groups: a large-sized group (shell length: 34.58 ${\pm}$ 2.23 mm, body weight: 12.43 ${\pm}$ 0.44 g) and a small-sized group (shell length: 20.60 ${\pm}$ 0.85 mm, body weight: 4.41 ${\pm}$ 2.30 g). Filtration rate and oxygen consumption increased with the increase of various temperatures and salinity levels. Also, the filtration rate and oxygen consumption of the small-sized group were higher than those of the large-sized group. These results indicate that the filtration rate and oxygen consumption of Anadara granosa bisenensis depends on environmental conditions, especially on water temperature and salinity.
