Clearance rate increases with flow rate up to some threshold. Food concentration in the range 40-1185 µg/Cl and relative column dimensions have no effect on clearance rate measured at a suitable flow rate. Following transfer of each species from ambient temperature (15 °C) to 10 °C and 20 °C clearance rate was found to be temperature dependent after an initial period of 3 days. After this initial period Q<sub>10</sub> values over 20 days were 1.5+/-0.2 for <i>O. edulis</i> and 3.3+/- 0.6 for <i>C. gigas</i> . Weight exponents were 0.74 for <i>O. edulis</i> and 0.68 for <i>C. gigas</i> . Models which predict flow requirement between 10 °C and 20 °C to give 90% clearance by each species were derived by integrating the data relating clearance rate to temperature and body size. For <i>O. edulis</i> FR = (0.47 + 0.04T) LW<sup>-0.26</sup> and for <i>C. gigas</i> FR = (-0.92 + 0.17T) LW<sup>-0.32</sup> , where FR is flow requirement (ml/min/g), LW is live weight (g) and T is temperature (C). The models probably lose their predictive value once oysters start to mature.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Flow requirements of the oysters <i>Ostrea edulis</i> L. and <i>Crassostrea gigas</i> Thunb. in an upwelling column system of culture","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":1981,"MonPub":null,"DateUpdate":"2020-11-02","DateCreate":"2009-05-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1981KY28600001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0044-8486(81)90127-7"},"refs":null,"anarec":{"AnaID":134943,"PubliDate":1981,"Pagination":"1-10","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
