In a comparison test at the <i>Breehorn</i> neither of the two devices was able to collect the total benthic macrofauna. The Van Veen grab takes only a limited top-layer of the sediment, missing most of the deep-living fauna. At test conditions, some heavy-shelled bivalve molluscs were scarcely or not at all sampled by the Van Arkel flushing sampler. In some sediments (firm clay, musselbeds) the flushing sampler cannot penetrate. When the two devices are used together, the benthic macrofauna can be sampled fairly completely. Finally the behaviour of some common bivalve molluscs during sampling by the Van Arkel flushing sampler is explained.","AbstractOtherLang":"Twee typen apparaten voor de bemonstering van de sublittorale benthische macrofauna zijn getest op hun efficiëntie. Deze apparaten zijn de Van Veen-happer en de Van Arkel-flushing sampler. Bij een vergelijkingsproef op de <i>Breehorn</i> bleek geen van beide apparaten de komplete macrofauna te kunnen bemonsteren. De Van Veen-happer kan maar tot een beperkte diepte in het sediment dringen en mist zodoende de meeste dieplevende bodemdieren. De Van Arkel-flushing sampler kan onder de testomstandigheden bepaalde zware tweekleppige schelpdieren niet of in beperkte mate bemonsteren. Ook in bepaalde sedimenten (stevige klei, mosselbanken) kan de flushing sampler niet indringen. Het gebruik van beide apparaten tezamen lijkt echter een vrij kompleet beeld van de benthische macrofauna te kunnen geven. Tot slot wordt het gedrag van enkele algemeen voorkomende tweekleppige schelpdieren tijdens de bemonstering met de Van Arkel-flushing sampler nader belicht.","BibLvlCode":"MS","StandardTitle":"Vergelijking van de bruikbaarheid van de Van Veen-happer met de Van Arkel-flushing sampler voor het bemonsteren van het sublittorale macrobenthos van de Waddenzee","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2025-07-22 01:33:06.175990","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":1982,"DateUpdate":"2025-07-15","DateCreate":"2001-07-04","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":12799,"ISBN":null,"PubliDate":1982,"IssueDate":null,"Volume":"1982","Issue":"9","Pagination":"9","Place":"Texel","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":5036,"SerRR":"Interne verslagen Nederlands Instituut voor Onderzoek der Zee.
