    中文摘要:
          于1996年12月至1997年1月在實驗室內研究了溫度對墨西哥灣扇貝(Argopecten irradians concentricus)的耗氧率和排泄(NH4-N)率的影響,實驗在投餌后6h,靜水(鹽度32)條件下進行,溶氧量和氨氮量分別采用Winkler滴定法和次溴酸鹽氧化法測定.實驗結果表明,在實驗溫度(10~31℃)條件下,不同規格(殼高1.6~4.8cm,軟體部干重0.0342~0.6908g)的墨西哥灣扇貝耗氧率的總平均值為2.35mg/(g·h).排泄率總平均值為350.89μg/(g·h).墨西哥灣扇見的耗氧量和排氧量都與扇貝體重呈明顯的冪函數關系.在10~28℃范圍內,不同規格的扇貝耗氧率都隨溫度的升高而增加;當水溫繼續升高到31℃時,耗氧率反而下降.在實驗溫度(10~31℃)條件下,扇貝的排泄率隨著溫度的升高而增加,溫度對墨西哥灣扇貝的耗氧率和排泄率的影響都可用指數方程表示.本實驗證實,高溫(31℃)將進一步提高墨西哥灣扇貝蛋白質的代謝水平.耗氧量(O)和排氨量(N)與溫度(t)、扇貝軟體部干重(W)二元線性回歸方程分別為:O=-587.804+36.787t+1697.864W;N=-92.344 9+4.534 1t+276.781 8W.復相關系數r分別為0.880 6和0.8035 ; F檢驗表明,兩個回歸方程均極顯著(F>F0.01).
    英文摘要:
          Effects of temperature on oxygen consumption rate and ammonia-N excretion rate of the Southern Bay scallop Argopecten irradians ceucoutricus (1.6-4.8 cm in shell height,0.039 2-0.690 8 g in dry weight of soft tissue) were studied in laboratory from Dec.30,1996 to Jan.28,1997.Under the controlled conditions of ambient temperature 10-31℃ and salinity 32,the concentration of dissolved oxygen and ammonia-N were determined by the Winkler method and the hypobromite method respectively.Results show that the range of oxygen consumption rate was from 1.06 to 5.18 mg/ (g·h),mean of 2.35 mg/(g·h).The relationship between oxygen consumption quantity(mg/h)and dry weight of soft-tissue (g) can be represented by the allometric equation O=aWb,b value was 0.748 2-0.937 3.The oxygen consumption rate increased with temperature increasing at 10-28℃,but reduced at 31℃.Effect of temperature on oxygen consumption rate (10-28℃) can be described by Os=r1er2t,r,the correlation coefficient was 0.194 0-0.944 0.The range of ammonia-N excretion rate was from 111.28 to 791.91 μg/(g·h),mean of 350.89 μg/(g·h).The relationship between ammonia-N excretion quantity (p.g/h) and dry weight of soft tissue can also be represented as the allometric equation:N=cWd,and d value was 0.765 4-0.852 8.The ammonia-N excretion rate increased at the temperature from 10℃ to 31℃,and the impact of temperature on ammonia-N excretion rate can be represented by Na=q1eq2t.r was 0.877 2-0.967 2.It is indicated that high temperature (31℃)can improve the level of protein metabolism in this experiment.The linear regression relationships among oxygen consumption quantity and temperature and dry weight of soft tissue can be described by O=-252.780+25.624t+1 509.917W,and ammonia-N excretion quantity by N=-38.758+2.794t+175.228W.the multiple r were 0.880 6 and 0.803 5,respectively.
