| Abstract | The population explosion of jellyfishAurelia coeruleaoccurred in Jiaozhou Bay, China in 2009. The potential predation impact ofA. coeruleaon zooplankton was investigated. Population clearance potential and residence time (t(1/2)) for copepods were calculated from laboratory clearance rates and measurements of jellyfish size and abundance from May to August 2009 in Jiaozhou Bay. Clearance rates varied widely with prey organisms, but they were not significantly different among various prey concentrations. Medusae captured rotifers, fish larvae and hydromedusae more efficiently than fish eggs, copepods and chaetognaths. Ephyrae captured rotifers and hydromedusae more efficiently than fish larvae and copepods. Clearance rate linearly increased with the cross sectional area ofA. coerulea(size from 0.3 to 7.1 cm). Water temperature also had a marked effect on clearance rate and this was related to the increased beat frequency as water temperature increased. In early May 2009,A. coeruleapotentially cleared the volume of water in the Bay less than 0.001 times a day, but this value was estimated to be more than 0.3 times a day in July. Thet(1/2)for copepods was less than 6 d in June and July. Abundances of copepods, hydromedusae and chaetognaths were extremely low in 2009 compared to 2008 and 2010 (jellyfish non-bloom years). Large predation pressure by theA. coeruleapopulation occurred to control zooplankton communities in Jiaozhou Bay.A. coerulea, when present at a high population level, can be a keystone species in Jiaozhou Bay and control the trophic structure here. |
