The flatfish eggs were observed alive for their developmental stage and aberrations from normal development. Flatfish eggs occurring in the winter ichthyoplankton of the southern North Sea were dab, <i>Limanda limanda</i>; flounder, <i>Platichthys flesus</i>; plaice, <i>Pleuronectes platessa</i>, and long rough dab, <i>Hippoglossoides platessoides</i>. Summer samples contained dab, turbot, <i>Psetta maxima</i>; little sole, <i>Buglossidium luteum</i>; common sole, <i>Solea solea</i>; Norwegian topknot, <i>Phrynorhombus norwegicus</i>, and lemon sole, <i>Microstomus kitt</i>. In winter as well as in summer eggs of dab were the most abundant in the southern North Sea with up to 249 eggs.m<sup>-3</sup> surface water in winter and 26 eggs.m<sup>-3</sup> in summer. The investigations revealed considerable quantities of abnormally developed flatfish embryos in the plankton samples. Highest malformation rates were recorded for the early stages of dab (44.4%) followed by flounder (41.3%) and plaice (26.0%) in winter; in summer these rates were for dab 18.9%, for turbot 14.1% and for little sole 12.5%. Generally malformation rates decreased with development. Areas of high malformation rates were off the river estuaries and in near-shore areas along the Dutch and German coasts. Malformation rates decreased with the distance from the coast. Causes and effects of the occurrence of malformations during embryonic development are discussed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Developmental defects in pelagic embryos of several flatfish species in the southern North Sea","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":1992,"MonPub":null,"DateUpdate":"2001-09-10","DateCreate":"2001-08-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1992JH41900023","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16360,"PubliDate":1992,"Pagination":"239-256","XtraPublOfAnaID":null,"ISBN":null,"Volume":"29","Issue":"1-3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
