| 摘 要： | 在浙江苍南霞关海域研究养殖密度(16.08、21.44、26.80、32.16、37.52 kg·m-3)、水层(0.50~1.25、1.00~1.75、1.50~2.25、2.00~2.75 m)、规格初始个体质量(28.5±2.2)、(35.4±1.7)、(57.0±2.7)g]对浅海筏架吊笼养殖刺参特定生长率和个体质量变异系数的影响,试验持续180 d。结果表明,养殖密度对刺参特定生长率和个体质量变异系数有显著(P<0.05)影响,随着养殖密度增大,特定生长率显著降低、生长变异系数显著增加。在本试验条件下,养殖水层对刺参生长无显著影响。规格显著(P<0.05)影响刺参特定生长率和个体质量变异系数,规格越大,特定生长率越高,个体质量变异系数越低。本试验表明,刺参浅海吊笼养殖密度应控制在26.80 kg·m-3以内,养殖水层以1.50~2.25 m为宜,结合南移养殖实际,建议选择初始个体质量33.3~62.5 g的苗种进行养殖。

| Abstract: | In the present study, effects of culture density (16.08, 21.44, 26.80, 32.16, 37.52 kg·m-3), depth layer (0.50-1.25, 1.00-1.75, 1.50-2.25, 2.00-2.75 m) and size initial individual weight (28.5±2.2), (35.4±1.7), (57.0±2.7) g] on specific growth rate (SGR) and coefficient of variation of individual weight (CV) of sea cucumber Apostichopus japonicas were explored. The experiment lasted for 180 d. It was shown that culture density had significant (P<0.05) influence on SRG and CV of sea cucumber. With the increase of culture density, SGR decreased yet CV increased significantly (P<0.05). In this study, culture layer had no significant influence on sea cucumber SRG and CV. However, culture size significantly (P<0.05) influenced SRG and CV of sea cucumber. With the increased culture size, SGR increased yet CV decreased significantly (P<0.05). It was suggested that culture density of sea cucumber should not exceed 26.80 kg·m-3, and the optimum culture layer and initial individual weight were 1.50~2.25 m and 33.3~62.5 g, respectively. |
