| 摘 要： | 为了探讨参藻混养生态系统中孔石莼Ulva pertusar、蛋白核小球藻Chlorella pyrenoidosa与刺参Apostichopus japonicus的相互作用,采用实验生态学方法进行了10~6、10~5 cells/mL两种浓度的蛋白核小球藻与孔石莼及刺参不换水混养的生态效应研究。结果表明:孔石莼和小球藻能有效地吸收养殖水体中的氮磷;10~6cells/mL浓度的小球藻在与孔石莼、刺参混养时对孔石莼有明显的抑制作用,而10~5 cells/mL浓度的小球藻对孔石莼有一定的抑制作用。研究表明,小球藻浓度为10~5 cells/mL的混养组在水质、刺参生长方面与孔石莼混养组相近,且能较好地抑制孔石莼过快生长。

| Abstract: | The ecological effects were studied in a 200 cm×50 cm×80 cm polyculture tank of sea cucumber Apostichopus japonicus with sea lettuce Ulva pertusar and green alga Chlorella pyrenoidosa at two concentrations of 106 cells/mL and 105 cells/mL without water exchanging in order to evaluate the interaction among sea lettuce,green alga and sea cucumber in the polyculture ecosystem.The results showed that the sea lettuce,and green alga effectively absorbed nitrogen and phosphorus in water for aquaculture.The green alga had significant inhibition of sea lettuce at alga concentration of 106 cells/mL and to some extent inhibition of sea lettuce at alga concentration of 105 cells/mL,at which water quality and growth of sea cucumber nearly were the same with those in the polyculture of sea cucumber with sea lettuce,especially restraining the growth of sea lettuce. |
