However, most of these models are site-specific and cannot be applied to other culture sites without the re-estimation of parameters or re-formulation of some processes. We aimed to develop a generic growth model suitable for application in contrasting environments, with a constant set of parameters. We tested the oyster-DEB model (Bourlès et al. 2009) for the stimulation of <em>C. gigas</em> growth in different cohorts (spats and adults) at major shellfish culture sites in France, in several years: Arcachon (1993–1994); Marennes-Oléron (2007); Quiberon (1999, 2000, 2001); Brest Harbour (2008); Mont-Saint-Michel Bay (2003); Baie-des-Veys (2002). These different ecosystems offer a wide range of values for the two forcing variables of the model: water temperature (range: 6-24 °C) and phytoplankton concentration (annual average: 110–700 × 10<sup>3</sup> cell L<sup>-1</sup>). The validation data (dry flesh mass of <em>C. gigas</em>) were obtained from various growth surveys carried out by IFREMER. The oyster-DEB model simulated the oyster growth dynamics of both spat and adult stages of <em>C. gigas</em> accurately over time at the various culture sites. The model captures: <em>i</em>) the active spring growth; <em>ii</em>) the timing and amplitude of spawning events; and <em>iii</em>) the lean periods (<em>i.e.</em> loss of dry flesh mass) in autumn and winter. The half-saturation coefficient <em>X</em><sub><em>k</em></sub> is the only model parameter that varied between sites and years. This environment-specific coefficient reflects variability in the food of the oysters: quantitative and qualitative effects of the inorganic material and of the phytoplankton species on the feeding response of <em>C. gigas</em>. With a single set of parameters (other than for <em>X</em><sub><em>k</em></sub>), this is thus the first bio-energetic growth model for <em>C. gigas</em> robust enough and of a sufficiently generic nature for the accurate simulation of oyster growth in different Atlantic ecosystems.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A single bio-energetics growth and reproduction model for the oyster <i>Crassostrea gigas</i> in six Atlantic ecosystems","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:31:43.033819","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"DEB Theory; Bivalves","OtherDescriptors":null,"Notes":null,"AnaPub":2011,"MonPub":null,"DateUpdate":"2020-06-23","DateCreate":"2015-11-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000298910200009","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.seares.2011.07.008"},"refs":null,"anarec":{"AnaID":251311,"PubliDate":2011,"Pagination":"340-348","XtraPublOfAnaID":null,"ISBN":null,"Volume":"66","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
