The growthrate is estimated to be 15 ± 7.77 µm.day-¹; - the juvenile benthic stage lasts about 40 days and allows the individual size to increase from 200 µm to about 1.4 mm, at a growth rate of 30 µm.day-¹. The growth average range is about 8 µm during the larval phase and can reach 260 µm in the juvenile phase. The survival rate of the clam's larvae during the larval phase (before metamorphosis and up to the pediveligerous phase, 200 µm), localised between the sixth and ninth day after fecundation, is about 86%. When the larva is metamorphosed and reaches 700 µm (the tenth to the fortieth day), this rate is 9.5%. Finally, it does not exceed 6% during the first phase of its benthic life (the fortieth to the sixty fifth day) when the individual measures 1.4 mm.","AbstractOtherLang":"L'analyse descriptive des phases de maturation, de fécondation, de l'embryologie, de la vie larvaire et juvenile de la palourde <i>Ruditapes decussata</i> dans le centre aquacole de Nador montre que: - le conditionnement à la maturation des géniteurs nécessite quatre à cinq semaines; - l'émission du globule polaire est observée 20 à 30 minutes après la fécondation; - le développement embryonnaire dure en moyenne 11 à 12 heures (près de 6 heures pour la segmentation, 5 à 6 heures pour la gastrulation); - la vie larvaire est de 6 à 9 jours, temps nécessaire pour que la larve passe du stade trochophore au stade pédivéligère ; le taux de croissance est de 15 ± 7,77 µm par jour ; - la phase juvenile benthique dure en moyenne 40 jours et permet à l'individu de passer de la taille de 200 µm à environ 1,4 mm; le taux de croissance est de 30 µm par jour. L 'ecart moyen de croissance est de 8 µm pendant la phase larvaire et peut atteindre 260 µm lors de la phase juvénile. Le taux de survie des larves de palourde est de 86% avant la métamorphose, c'est-à-dire jusqu'au stade pédivéligère (200 µm), entre le sixième et le neuvième jour après la fécondation, 9,5% lorsque la larve se métamorphose, et atteint la taille de 700 µm, du dixième au quarantième jour et enfin, il ne dépasse pas les 6% pendant la première phase de sa vie benthique, du quarantième au soixante-cinquième jour, lorsque l'individu mesure 1,4 mm.","BibLvlCode":"AS","StandardTitle":"Étude préliminaire de l'embryologie, de la vie larvaire et juvénile de la palourde <i>Ruditapes decussata</i> (L.) en milieu contrôlé = Preliminary study of the embryology, larval and juvenile life of the clam <i>Ruditapes decussata</i> (L.) in controlled environment","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"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":1998,"MonPub":null,"DateUpdate":"2002-05-30","DateCreate":"2001-03-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":7115,"PubliDate":1998,"Pagination":"19-24","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43514,"SerRR":"Marine Life = Vie Marine.
