Shipboard grazing experiments and countings of zooplankton were carried out at different depths of the water column during 24- to 48-h measurements of intervals of 4 or 6 h. In the English Channel, in late April, a shallow homogeneous water column (50 m), higher feeding rates in the deeper layers were observed due to the larger abundance of <i>Pseudocalanus elongatus</i>, during the 24-h period, resulting in an absence of upwards swarming at night, but an evident higher feeding at night. At the same station, the other dominant copepod <i>Oithona</i> showed higher feeding rate in the daytime. Secondly, in the Southern Bight, another shallow homogeneous system (25 m), vertical migration together with increasing feeding at night could be observed for <i>Temora longicornis</i> and <i>Pseudocalanus elongatus</i> in the month of May. Thirdly, in the northern North Sea, phytoplankton and zooplankton vertical distribution are strongly correlated but limited in the first 30 m above the thermocline. No vertical movements in this narrow space were observed, but there was a preference for a definite depth for each of the copepod species.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Feeding rhythms and vertical distribution of marine copepods","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1985,"MonPub":null,"DateUpdate":"2021-01-11","DateCreate":"2021-01-11","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1985AYN8600011","VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":332494,"PubliDate":1985,"Pagination":"487-497","XtraPublOfAnaID":null,"ISBN":null,"Volume":"37","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42490,"SerRR":"Bulletin of Marine Science.
