实验测定了不同体质量的仿刺参(Apostichopus japonicus (Selenka))在不同温度条件下,消化道的排空时间、排便量和排便率。按仿刺参体质量大小分设10 g ±0.5 g、40 g ±2.0 g和70 g ±3.5 g三个体质量组,以及6、9、12、15、18、21℃共6个温度梯度。结果表明,各体质量组仿刺参的排空时间均随温度的升高,具有先增大后减小的趋势,10 g ±0.5 g和40 g ±2.0 g组分别在12和15℃时排空时间最长,且在9～15℃时差异不显著(P＞0.05),但显著大于其他温度组(P＜0.05),70 g ±3.5 g组仿刺参在12℃时的排空时间达各组最大值36.4 h。在6、18和21℃温度条件下,仿刺参的排空时间随体质量的增大总体呈增长趋势,各温度组仿刺参的排便量均随体质量的增大而增加。仿刺参的个体排便率随体质量的增加而增大,而单位体质量排便率多数随体质量增大而减小。10 g ±0.5 g和40 g ±2.0 g组的排便率均在6℃时最高,70 g ±3.5 g组在9℃时达最高,然后降低。温度和体质量对仿刺参排空时间和排便量均有极显著的影响(P＜0.01),二者的交互作用对排空时间的影响也是极为显著的(P＜0.01),但对排便量的影响不显著(P＞0.05)。

The emptying time of digestive duct, feces quantity and defecation rate of sea cucumber Apostichopus japonicus (Selenka) of different body weights were investigated at a graded temperature condition. Three sea cu-cumber, body weight groups of 10 ± 0.5 g, 40 ± 2.0 g, 70 ± 3.5 g, and six temperature gradients of 6, 9, 12, 15, 18, 21 ℃ were set. The results showed that emptying time had the trend of rising first and declining afterwards with rising temperature. The groups of 10 ± 0.5 g at 12℃and 40 ± 2.0 g at 15℃had the longest emptying time. The time had no significant difference at 9-15℃ (P>0.05) but was much longer than other temperature groups (P<0.05).The time of 70 ± 3.5 g groups reached maximal value of 36.4 h at 12℃. Emptying time rose with increasing body weight at temperature of 6, 18 and 21℃, while feces quantity increased with body weight at all temperature groups. Individual defecation rate increased with body weight while weight specific defecation rate decreased with body weight. Defecation rates of groups 10 ± 0.5 g and 40 ± 2.0 g at 6℃and groups 70 ± 3.5 g at 9℃reached a climax and then declined. Temperature and body weight all affected emptying time and feces quantity significantly (P<0.01), and effect of interactive effects of the two factors on emptying time was significant (P<0.01) while not significant on feces quantity (P>0.05).
