Annual formation of natural growth rings on the shell surface was validated by stable isotope (δ<sup>18</sup>O and δ<sup>13</sup>C) analysis. A von Bertalanffy growth function (<i>H</i><sub></sub> = 58.9 mm.(1-e<sup>−0.604.(t +0.235)</sup>)) was fitted to size-at-age data of 249 individuals. Annual somatic and gonad production amounted to 19.74 kJ m<sup>−2</sup> and 0.98 kJ m<sup>−2</sup> y<sup>−1</sup>, respectively. Total mortality rate Z was estimated to be 1.716 y<sup>−1</sup>. Net growth efficiencies (ranging from 45% in 1-y-old to 11% in 6-y-old individuals) were in the same range as in other short-lived scallops. Individual growth, however, was distinctly slower in this population than in other <i>A. opercularis</i> populations from similar latitudes, most likely due to a more stressful environment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Population dynamics and metabolism of <i>Aequipecten opercularis</i> (L.) from the western English Channel (Roscoff, France)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-31 01:31:04.941952","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":"Bivalvia; Energy budget; Metabolism; Mortality; Pectinidae; Population dynamics","Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2020-10-02","DateCreate":"2004-06-29","SecASFANote":"Population dynamics, metabolism of <i>Aequipecten opercularis</i>, English Channel","ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000222189400003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.seares.2003.07.005"},"refs":null,"anarec":{"AnaID":63788,"PubliDate":2004,"Pagination":"33-44","XtraPublOfAnaID":null,"ISBN":null,"Volume":"52","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
