中文摘要：采用室内实验生态学方法,进行了尖紫蛤的耗氧率和排氨率的研究。结果表明,盐度和pH对不同规格尖紫蛤的耗氧率和排氨率影响明显。尖紫蛤的耗氧率和排氨率与盐度之间的关系可分别用二次多项式OR=-c1+d2S-d3S2,NR=c2+d4S-d5S2表示,在盐度10时耗氧率和排氨率达到最大值,当盐度超过10时反而下降;pH6.4—8.4时,3种规格尖紫蛤的单位体质量耗氧率和排氨率随pH升高而增强,pH大于8.4时耗氧率和排氨率降低。盐度2—18时,不同规格的尖紫蛤个体O:N值为:8.319—14.840,平均为11.476,在14时O:N出现峰值;pH6.4—9.4时,不同大小的尖紫蛤个体O:N值为:2.377—11.502,平均为8.547,在8.4时O:N出现峰值。

外文摘要：The oxygen consumption rate and ammonia excretion rate of Soletellina acuta were studied by ecological methods in laboratory. The results showed that the oxygen consumption rate and ammonia excretion rate of S. acuta with different sizes under different salinity and different pH condition had significant difference （P〈0.05）. The relationship of the oxygen consumption rate and ammonia excretion rate with the salinity could be expressed as the following quadratic polynomial models： OR =-c1＋ d2S-d3$2 and NR = c2 ＋ daS-dsS2, respectively. The oxygen consumption rate and ammonia excretion rate reached to a maximum value at the salinity of 10, but decreased above the salinity of 10. When the pH value was ranged from 6.4 to 8.4, the oxygen consumption rate and ammonia excretion rate per mass unit of S. acuta in three sizes increased as the pH value rose. The oxygen consumption rate and ammonia excretion rate decreased above the pH value of 8.4. At the salinity range of 2 to 18, the O：N value of deferent sizes of S. acuta was changed among 8.319 to 14.840, and the average value was 11.476. The O：N value reached to a peak level at the salinity of 14. At the pH value range of 6.4 to 9.4, the O：N value of S. acuta with deferent sizes was changed from 2.377 to 11.502, and the average value was 8.547. The O：N value reached to the peak at the pH value of 8.4.
