This species reproduced throughout the year, and the adults showed a large abundance peak in June/July and a small peak in September/October. Females usually outnumbered males, comprising 61.4% of the annual mean. The composition of ovigerous females varied from 7.9 to 100%, with an annual mean of 55.7%. Adult prosome length was consistently large throughout winter and spring, and decreased with increasing temperature in summer and fall. Egg diameter varied from 98 to 121?µm, and was negatively correlated to temperature. The seasonal variation in clutch size (range: 15.1 to 38.2 eggs) was bicyclical, with peaks in May and December. The egg production rate of breeding females was low in January to March (mean: 2.3 eggs female<sup class=\"a-plus-plus\">-1</sup> d<sup class=\"a-plus-plus\">-1</sup>), while it was constantly high from mid-May to early October (mean: 12.1 eggs female<sup class=\"a-plus-plus\">-1</sup> d<sup class=\"a-plus-plus\">-1</sup>). The specific egg production rate for the breeding females was highly correlated to temperature; it increased linearly from 0.03 d<sup class=\"a-plus-plus\">-1</sup> at 9?°C to 0.27 d<sup class=\"a-plus-plus\">-1</sup> at 26?°C. Compared to other co-occurring copepods, the reproductive rate of <em class=\"a-plus-plus\">P</em>. <em class=\"a-plus-plus\">marinus</em> was lowest, which is one of the reasons why this species never dominates in this inlet.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Seasonal reproductive biology of the egg-carrying calanoid copepod <i>Pseudodiaptomus marinus</i> in a eutrophic inlet of the Inland Sea of Japan","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-27 01:31:09.142696","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2013-10-08","DateCreate":"2013-10-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1997XE76500006","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s002270050106"},"refs":null,"anarec":{"AnaID":229645,"PubliDate":1997,"Pagination":"409-414","XtraPublOfAnaID":null,"ISBN":null,"Volume":"128","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
