在室内研究了温度对缢蛏耗氧率和氨排泄率的影响。结果表明，在环境温度控制在15~30℃的条件下，耗氧速率(O) [mg/h]与软组织干重W(g)的关系可用异速生长方程O = aW~b表示，氨排泄速率(N)[μg/h]与软组织干重W(g)的关系也可用异速生长方程N = cW~d表示。结果表明，耗氧量（O_s）[mg/g·h]和氨排泄率（N_a）[μg/g·h]与水温呈显著正相关，水温在15~30℃范围内可降低蛋白质代谢水平。耗氧量(O)与温度、软组织干重的线性回归关系为：O = -0.3703 + 0.3204W + 0.0298T，氨排泄率(N)为：N = -154.0677 + 69.7488W + 7.9332T，多重相关系数分别为0.9773和0.9228。
The effects of temperature on oxygen consumption rate and ammonia excretion rate of the constricted tagelus (Sinonovacula constricta) were studied in laboratory. The results showed that under the controlled conditions of ambient temperature 15～30 ℃, the relationship between oxygen consumption rate (O) [mg/h] and dry weight of soft tissue W(g) can be represented by the allometric equation O = aW~b, The relationship between ammonia excretion rate (N)[μg/h] and dry weight of soft tissue W(g) can also be represented by the allometric equation N = cW~d. It is indicated that the oxygen consumption rate (O_s)[mg/g·h] and ammonia excretion rate (N_a)[μg/g·h] are correlated positively with the water temperature and the high temperature can reduce the level of protein metabolism at the temperature range 15～30 ℃. The linear regression relationships among oxygen consumption rate (O) and temperature and dry weight of soft-tissue can be described by O = -0.3703 + 0.3204W + 0.0298T, and ammonia excretion rate (N) can be done by N = -154.0677 + 69.7488W + 7.9332T, the multiple relation coeffreient were 0.9773 and 0.9228 respectively.
