Eburneus</i> Gould and <i>B. Trigonus</i> Darwin, cultured singly or in pairs for 2 1/2 yr, were compared. All specimens, collected from Tokyo Bay and studied between 1985 and 1987, were fed on newly hatched <i>Artemia</i> sp. larvae (lsquoTetrarsquo strain) and phytoplankton culture and were maintained under constant temperature (20°C) and controlled photoperiods (10 h light:14 h dark). The breeding frequencies of these three species were equally high, from 2 to 4 broods mo-1 in the first year; they were relatively high between October and February, averaging 3 broods mo-1. <i>B. amphitrite, B. Eburneus</i> and <i>B. Trigonus</i> produced 24, 21 and 11 broods yr-1, respectively. Brood size was quite variable among the three species examined, yielding 4000 embryos brood-1 in <i>B. Amphitrite</i> and <i>B. Eburneus</i> and 6000 in <i>B. Trigonus</i>. Brood interval averaged 4 to 9 d. The moult occurred over short intervals of 4 to 10 d moult-1. Both breeding and moulting frequencies were influenced by low temperature and starvation. Self-fertilization was observed in all species and was more frequent in <i>B. Amphitrite</i> than in <i>B. Eburneus</i> and <i>B. Trigonus</i>. Nutritional condition and temperature seemed to be the main external factors regulating both breeding and moulting processes in barnacles.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Breeding and moulting of barnacles under rearing conditions","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:11.352907","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1991,"MonPub":null,"DateUpdate":"2008-04-03","DateCreate":"2008-03-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1991FA14300011","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":121058,"PubliDate":1991,"Pagination":"83-89","XtraPublOfAnaID":null,"ISBN":null,"Volume":"108","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
