As well as in 1994 the distribution and the biomass of all the shellfish species present in the Fore Delta, are being represented. Also attention is paid to the fishery on cockles, which took place the end of 1994 in the river mouth of Haringvliet. The fishers fished up most of the adult cockles in the mouth of Haringvliet, but in the fall of 1994 a great increase of young cockles took place. The great quantities of fresh water that left the Haringvliet locks, in the spring of 1995 in the Netherlands, had a disastrous effect on both young and still present adult cockles. Almost all cockles died. Also the other local shellfish suffered through it. In other places in the Fore Delta, however, an increase has been noted, in particular of razor-fish and half truncated sand shells (<i>Spisula subtruncata</i>). The total shellfish biomass in the Fore Delta has increased with factor six in one years time. Because there will be no cockle fishery in the Fore Delta in 1995 (and possibly also in 1996), hopes for the study on the direct, short-term effects of shellfishery are pinned on <i>Spisula subtruncata</i>. When the supply of this species develops well, new fishing may take place during the running time of VIEVO. In which case, new locations for effect research can possibly be chosen.","AbstractOtherLang":"In dit rapport worden de resultaten gepresenteerd van de schelpdierbestandsopname die door het RIVO-DLO in 1995 in de Voordelta is uitgevoerd in het kader van het project \"Effecten van de schelpdiervisserij op het bodemleven in de Voordelta\" (VIEVO). Evenals in 1994 worden verspreiding en biomassa van alle in de Voordelta aangetroffen schelpdiersoorten gepresenteerd. Ook wordt aandacht besteed aan de visserij op kokkels, die eind 1994 in de monding van het Haringvliet heeft plaatsgevonden.De vissers hebben een groot deel van de adulte kokkels in de Haringvlietmond opgevist, maar er heeft een grote aanwas van jonge kokkels in het najaar van 1994 plaatsgevonden. De grote hoeveelheden zoetwater die in het voorjaar van 1995 Nederland via de Haringvlietsluizen hebben verlaten, hebben op deze jonge kokkels, en ook op de nog aanwezige adulte exemplaren, echter een desastreus effect gehad. Bijna alle kokkels zijn dood gegaan. Ook de andere schelpdieren ter plaatse hebben hieronder te lijden gehad.Elders in de Voordelta is daarentegen een grote toename geconstateerd van vooral mesheften en halfgeknotte strandschelpen (<i>Spisula subtruncata</i>). De totale schelpdierbiomassa in de Voordelta is in een jaar tijd met een factor zes toegenomen. Omdat er in 1995 (en mogelijk ook in 1996) geen kokkelvisserij in de Voordelta zal zijn, is voor de studie van de directe, korte-termijneffecten van de schelpdiervisserij de hoop gevestigd op <i>Spisula subtruncata</i>. Wanneer het bestand van deze soort zich goed ontwikkelt, zal er mogelijk nog tijdens de looptijd van VIEVO op gevist worden. In dat geval kunnen mogelijk nieuwe locaties voor het effectonderzoek worden gekozen.","BibLvlCode":"MS","StandardTitle":"Effecten van de schelpdiervisserij op het bodemleven in de Voordelta: De schelpdierbestanden in de Voordelta in 1995","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":1996,"DateUpdate":"2025-07-18","DateCreate":"2000-08-24","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":null,"monrec":{"MonID":669,"ISBN":null,"PubliDate":1996,"IssueDate":null,"Volume":"96","Issue":"11","Pagination":"39","Place":"Den Haag","Edition":null,"BRefXtra":null,"BRefXtraRR":null,"SerID":33963,"SerRR":"BEON Rapport = BEON-report.
