Indirectly estimated respiration based on the degrowth rate, and the directly measured respiration were in satisfactory agreement. The respiration rate (R, µl O<sub>2</sub> d<sup>-1</sup> ) of different sized unfed medusae was correlated with the body dry weight (W, mg) according to the equation R = 10.89W<sup>0.86</sup>. No convincing difference in respiration rate was observed between fed and unfed jellyfish. An energy budget showed that the lowest prey concentration resulting in maximum growth of <i>A. aurita</i> was 68 µg C l<sup>-1</sup> while the prey biomass necessary for maintaining the respiratory demand was 13 µg C l<sup>-1</sup> .","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Size dependent respiration and growth of jellyfish, <i>Aurelia aurita</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2003-06-19","DateCreate":"2003-02-04","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":31938,"PubliDate":1997,"Pagination":"307-312","XtraPublOfAnaID":null,"ISBN":null,"Volume":"82","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43909,"SerRR":"Sarsia.
