Retention efficiency was estimated by comparing particle size distributions at the output of experimental chambers containing the species and controls. Although particles ranging from 4 to 12 µm were collected by <i>L. conchilega</i>, no upper threshold or maximum retention rate was reached within this range. In contrast, <i>C. gigas</i> showed retention starting at 2 µm, and reaching an upper threshold at 6 to 8 µm. Based on our results, feeding competition is likely to occur between <i>C. gigas</i> and <i>L. conchilega</i>. Standardised filtration rates reached 0.225 l h<sup>-1</sup> g dmw<sup>-1</sup> (±0.08) for <i>L. conchilega</i> and 2.43 l h<sup>-1</sup> g dmw<sup>-1</sup> <i>C. gigas</i> for animals of 1 g dry meat weight (dmw). Assimilation rates, 0.44 for <i>L. conchilega</i> and 0.49 for <i>C. gigas</i>, were similar for the two species. Respiration rates were estimated at 0.113 and 0.68 ml O<sub>2</sub> h<sup>-1</sup> for <i>L. conchilega</i> (Allometric coefficient=0.534) and <i>C. gigas</i> respectively. Therefore polychaete scope for growth (SFG) (4.01 J h<sup>-1</sup> g dmw<sup>-1</sup>) was significantly lower when compared with <i>C. gigas</i> SFG (61.96 J h<sup>-1</sup> g dmw<sup>-1</sup>). The impact of the <i>L. conchilega</i> population on that of cultivated oysters was evaluated from these results and field population assessment of both species. Based on field population estimates, <i>L. conchilega</i> was responsible for a 19% decrease in the carrying capacity and 30% of the oxygen depletion from the total activity of both species. However, <i>L. conchilega</i> SFG was only 16% of that of the <i>C. gigas</i> population. Several hypotheses regarding population interactions are discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Comparative physiological energetics of two suspension feeders: polychaete annelid <i>Lanice conchilega</i> (Pallas 1766) and Pacific cupped oyster <i>Crassostrea gigas</i> (Thunberg 1795)","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":2000,"MonPub":null,"DateUpdate":"2014-08-20","DateCreate":"2008-03-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000084394500013","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/S0044-8486(99)00216-1"},"refs":null,"anarec":{"AnaID":120648,"PubliDate":2000,"Pagination":"171-189","XtraPublOfAnaID":null,"ISBN":null,"Volume":"181","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
