The main results were: Growth rate was negatively correlated with tidal level (time of exposure to air). Slow growth goes with heavy shells. At the same tidal level growth was much faster at Horntje than at the Balgzand. With increasing time of exposure to the air condition factor decreased at Horntje, as has been observed by many authors. At the Balgzand, however, an inverse relationship was found. Specific gravity of the shell did not vary, neither with level nor with place. The shells were found to grow allometrically.","AbstractOtherLang":"Van april tot november 1970 is een onderzoek gedaan naar de relatie tussen de groei van <i>Mytilus edulis</i> L., de litorale hoogte waarop hij is gevestigd en zijn standplaats (Horntje versus Balgzand). Het onderzoek heeft tot de volgende condclusies gleid: Mossels die hoog in de getijzone zijn gevestigd blijken een geringere groeisnelheid te hebben dan die uit de lagere delen der zone, ze hebben tevens een zwaardere schelp. De groei van zowel de schelp als het vlees is op het Balgzand slecht in verhouding tot die op het Horntje: de Conditie Index - d.w.z. het ADW per inwendig schelpvolume - is er eveneens zeer laag. Als mogelijke oorzaak is de hoge temperatuur en het hoge slibgehalte genoemd. De Conditie Index neemt bij de Horntje-mossels af met de toenemende litorale hoogte, hetgen overeenkomt met de bevindingen van de meeste onderzoekers. Bij de Balgzand-mossels is echter het tegenovergestelde geconstateerd.","BibLvlCode":"MS","StandardTitle":"De groei van <i>Mytilus edulis</i> L. als functie van de onderdompelingstijd","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2025-07-25 01:33:49.256478","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1973,"DateUpdate":"2025-07-18","DateCreate":"2001-07-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":12997,"ISBN":null,"PubliDate":1973,"IssueDate":null,"Volume":"1973","Issue":"2","Pagination":"29","Place":"Texel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":5697,"SerRR":"NIOZ-rapport.
