The filtration, respiration and assimilation rates in the suspension feeding bivalves, <I>Limnoperna fortunei kikuchii and Mactra veneriformis</I> were examined.<BR>The results can be summarized as follows: 1) Filtration and respiration rates per unit wet tissue weight of both <I>L. f. kikuchii and M. veneriformis</I> increased in accordance with increase in water temperature and decrease in the shell-length. These values increased in growth phase. 2) Differences in the circumstances of bivalves habitat, such as intertidal and undertidal zones affected the daily changes of the filtration and feces excretion rates. 3) The filtration and respiration rates of both bivalves were expressed by the following Equations:<BR>•<I>Limnoperna fortunei kikuchii</I><BR>F (m<I>l</I>⋅g<SUP>-1</SUP>⋅hr<SUP>-1</SUP>) =7.8×10<SUP>-3</SUP>×t<SUP>2.33</SUP>×W<SUP>-1.19</SUP> (r<SUP>2</SUP>=0.97, n=16, wet tissue weight 0.144-0.356 g and 10-28°C in water temperature) .<BR>R (mg-O<SUB>2</SUB>⋅g<SUP>-1</SUP>⋅hr<SUP>-1</SUP>) =7.8×10<SUP>-6</SUP>×t<SUP>3.01</SUP>×W<SUP>-0.29</SUP> (r<SUP>2</SUP>=0.98, n=17, wet tissue weight 0.151-0.478 g and 10-28°C in water temperature)<BR>•<I>Mactra veneriformis</I><BR>F (m<I>l</I>⋅g<SUP>-1</SUP>⋅hr<SUP>-1</SUP>) =4.9×t<SUP>0.77</SUP>×W<SUP>-0.90</SUP> (r<SUP>2</SUP>=0.94, n=16, wet tissue weight 0.237-3.488 g and 10-28°C in water temperature) .<BR>R (mg-O<SUB>2</SUB>⋅g<SUP>-1</SUP>⋅hr<SUP>-1</SUP>) =5.0×10<SUP>-4</SUP>×t<SUP>1.63</SUP>×W<SUP>-1.29</SUP> (r<SUP>2</SUP>=0.99 and n=16, wet tissue weight 0.237-3.488 g and 10-28°C in water temperature)<BR>4) Assimilation rate of both bivalves decreased with the increase of shell-length and the decrease of water temperature. <I>M. veneriformis</I> generaly had a higher assimilation rate than <I>L. f. kikuchii</I>.
