| 摘要: |
| 采用实验生态学方法，以紫刺参为研究对象，分别研究了6个温度条件下（14℃，18℃，22℃，26℃，30℃，34℃）和5个盐度条件下（23，27，31，35，39）紫刺参稚参和对照组普通刺参稚参的存活、生长及体色变化情况。结果表明：水温22℃实验组紫刺参在不同水温实验中的成活率最高，为87.0%，水温18℃和34℃时的紫刺参成活率高于普通刺参；水温高于22℃实验组的紫刺参体长增长显著高于普通刺参，以水温为14℃实验组的紫刺参SGR最低，为4.63%/d。盐度31实验组紫刺参在不同盐度实验中的成活率最高，为86.3%；紫刺参与普通刺参SGR随盐度的升高均呈现先上升后下降的趋势，在盐度39实验组中，紫刺参SGR为5.47%/d，显著高于普通刺参；在不同环境条件下，刺参开始着色到变色完成的时间为7—23d，当水温为22℃、盐度为31时，紫刺参在32—48日龄完成变色，随着盐度或水温的改变，变色时间逐渐从16d延长至22d。紫刺参相比普通刺参有更广的适温范围和耐高盐能力。 |

| Abstract: |
| To investigate the effects of temperature and salinity on survival, growth, and coloration of juvenile purple sea cucumber Apostichopus japonicus Selenta, purple and normal sea cucumbers were reared in different temperatures (14℃, 18℃, 22℃, 26℃, 30℃, 34℃) and salinities (23, 27, 31, 35, 39). The results show that survival rate of purple sea cucumber was the highest in 22℃ experimental group, reaching 87.0%, much higher than the normal ones at 18℃ and 34℃. The body length of purple sea cucumber was significantly longer than normal ones when water temperature was above 22℃, and the specific growth rate (SGR) of the purple sea cucumber was 4.63%/d at 14℃. With the salinity increase, the SGR of the sea cucumber increased first and then decreased. The SGR of purple sea cucumber was 5.47%/d at salinity 39, significantly higher than normal ones. The duration of coloring could be completed between Day 7 to Day 23, depending on environmental conditions. When water temperature was 22℃ and salinity 31, it took 32-48 days to complete the coloration for the purple sea cucumber, and with change in salinity or water temperature, the span of coloration could expanded from 16d to 22d. Compared with normal sea cucumber, purple sea cucumber has wider temperature range and high salinity tolerance. |
