| 摘 要： | 采用交叉实验和水母体培养的方法,研究了不同生活史阶段的海月水母及海蜇之间的相互捕食关系。海月水母螅状体(口柄直径约为1mm)能够捕食海蜇碟状体及伞径≤8mm的海蜇幼体;海月水母的碟状体只能够捕食海蛰碟状体;伞径100mm的海月水母体能够捕食海蜇碟状体及伞径≤30mm的海蛰幼体。在海蜇对海月水母的捕食实验中发现,伞径≥10mm的海蜇幼体对海月水母的碟状体有捕食行为。通过对两种水母相互捕食关系的研究,笔者认为海月水母捕食海蜇的能力明显强于海蜇捕食海月水母的能力。这或许有助于解释近年来海月水母不断暴发而海蜇资源日渐减少的现象,有助于改进海蜇人工增殖放流措施,提高放流效果。 |

| Abstract: | A laboratory experiment was conducted to investigate the predator-prey relationship at different life stages between Aurelia sp.1 and Rhopilema esculenta.The results showed that Scyphistomae of Aurelia sp.1,with 1mm oral disk diameter,could prey on ephyrae and medusa of R.esculenta whose oral disk was no more than 8mm in diameter;and in the ephyrae larval stage,Aurelia sp.1 was able to prey on R.esculenta’s;Aurelia sp.1 medusa with 100mm bell diameter could still feed upon both ephyrae larval and early medusa(bell diameter ≤ 30mm) of R.esculenta.However,the early medusa of R.esculenta whose umbrella diameter was no less than 10mm could absolutely prey on Aurelia sp.1 ephyrae larval.Aurelia sp.1 had stronger ability to prey on R.esculenta.These results revealed the relationship between the outbreak of Aurelia sp.1 and the decrease of R.esculenta resource.It was helpful to improve the effect of releasing R.esculenta. |
