Abstract

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.
