| 摘 要： | 以文蛤(Meretrix petechialis)为实验对象,采用实验室静水法和间歇式呼吸测量法,通过测定摄食率、耗氧率、排粪率、排氨率等生理参数,研究了不同水温下不同规格文蛤的生理代谢情况。结果显示:供试文蛤的摄食率、排氨率、排粪率、耗氧率分别在25~30、20~30、15~20、35 ℃存在最大值。随水温升高,文蛤摄食率和排氨率先增加后下降,而排粪率逐渐降低,耗氧率逐渐升高。实验条件下,大、中、小规格的文蛤(壳长范围30~46 mm)摄食率为0.015~0.043 mg·g-1·h-1,排氨率为1.26~135.25 μg·g-1·h-1,排粪率为2.173~15.908 μg·g-1·h-1,耗氧率为0.290~1.780 mg·g-1·h-1。研究结果可为探明文蛤在不同季节的生理代谢规律、指导文蛤养殖产业发展提供借鉴。 |

| Abstract: | In the present study, Meretrix petechialis was selected as the study object. Based on the laboratory still water method and intermittent respiration measurement method, the effects of different temperature on ingestion rate, oxygen consumption rate, faecal egestion rate, and ammonia excretion rate of Meretrix petechialis were explored. It was shown that the maximum values of ingestion rate, ammonia excretion rate, faecal egestion rate and oxygen consumption rate were found under 25-30, 20-30, 15-20, and 35 ℃, respectively. With the elevated water temperature, the ingestion rate and ammonia excretion rate of Meretrix petechialis increased first and then decreased, while the faecal egestion rate gradually decreased, yet oxygen consumption rate increased. Under the experiment conditions, the variation ranges of ingestion rate, ammonia excretion rate, faecal egestion rate and oxygen consumption rate were 0.015-0.043 mg·g-1·h-1, 1.26-135.25 μg·g-1·h-1, 2.173-15.908 μg·g-1·h-1 and 0.290-1.780 mg·g-1·h-1, respectively. These results could provide references for the study of physiological metabolism of Meretrix petechialis in different seasons and guide the development of corresponding mariculture. |
