摘要
于2008年6月—2009年5月对不同生长阶段仿刺参Apostichopus japonicus的代谢率进行了跟踪观测。结果表明,温度对不同生长阶段仿刺参的耗氧率和排氨率均有显著影响(P〈0.05),相同温度下,体重对耗氧率和排氨率的影响也有规律性。A、B组仿刺参(12 g以下)在12.7~16.2℃下,耗氧率和排氨率缓慢上升;在16.2~22.1℃下迅速上升,并在22.1℃时达到最大值[(37.13±1.33)、(35.38±0.55)μg/(g.h)和(0.55±0.054)、(0.54±0.053)μg/(g.h)];在22.1~26.1℃下缓慢下降。与之相反,其他3组仿刺参(18 g以上)在12.7~16.2℃下其耗氧率和排氨率平稳上升,在16.2℃时达到最大值;在16.2~22.1℃下,迅速下降到较低水平;在22.1~26.1℃下,在较低水平上平稳下降,26.1℃时达到最低值。
The respiration and excretion were monthly determined in the different developmental stages of sea cucumber Apostichopus japonicus from June in 2008 to May in 2009.It was found that temperature showed significant effect on the oxygen consumption and ammonia excretion at different developmental stages(P〈0.05),and at the same temperature,body weight had also regular influence on the oxygen consumption and ammonia excretion.The oxygen consumption and ammonia excretion were found to be steady rise in the small sea cucumber with body weight of less than 12 g at water temperature between 12.7 ℃ and 16.2 ℃,and to be sharp increase at 16.2-22.1 ℃,the maximum of(37.13±1.33)μg/(g·h) for oxygen consumption and(0.55± 0.054)μg /(g·h) for ammonia excretion at 22.1 ℃.For the large sea cucumber,however,the oxygen consumption and ammonia excretion were found to be steady rise between 12.7 ℃ and 16.2 ℃,the maximal oxygen consumption of(33.99±0.59)μg/(g·h) and ammonia excretion of(0.49± 0.047)μg/(g·h) being observed at 16.2 ℃.Between 16.2 ℃ and 22.1 ℃,the rates were decreased promptly to the low level and at 22.1-26.1 ℃,the rates was found to be steadily low,the minimal oxygen consumption of(6.75±0.41)μg/(g·h) and ammonia excretion of(0.11±0.028)μg/(g·h) appearing at 26.1 ℃.
