摘要The moon jellyfish (Aurelia sp. 1) is thought to be a nuisance for the sea cucumber aqua-culture, which commonly occur in the sea cucumber (Apostichopus japonicus) culture ponds of the Yellow Sea, China. To develop an appropriate method to control Aurelia sp. 1 blooms, the toxic effects of tea saponin on Aurelia sp. 1 ephyrae and polyps were tested in laboratory experiments. Our results revealed that tea saponin caused significant morphological changes, behavioral abnormality and mortality in Aurelia sp. 1 ephyrae and polyps in 24 h and 48 h exposure experiments. The 24 h and 48 h median lethal concentrations (LC50) values of tea saponin for Aurelia sp. 1 ephyrae were 1.9 and 1.1 mg L-1 respectively, while the LC50 value for Aurelia sp. 1 polyps was 0.4 mg L-1 after 24h and 48 h of exposure to tea saponin. Comparison with literature results of tea saponin on A. japonicus indicates that the resistance of A. japonicus to tea saponin is 12-18 times greater than that of Aurelia sp. 1 ephyrae. Therefore, the appropriate tea saponin dosage for the control of Aurelia sp. 1 should be paid enough attention in order to minimize possible damage for sea cucumber. We suggest that the recommended level of tea saponin to eradicate Aurelia sp. 1 ephyrae and polyps in sea cucumber culture ponds be lower than 1.35 mg L-1.
