Óf de Kokkel in een gebied voorkomt is afhankelijk van een succesvolle broedval in de zomer. Een grote zoetwaterafvoer van de Schelde vermindert het voorkomen van Kokkels in het oostelijk deel van de Westerschelde. Hoewel die situatie zich inderdaad heeft voorgedaan, zijn de schommelingen toch vooral het gevolg van variaties in de kokkelbroedval. Strenge winters en predatie op het kokkelbroed door garnalen en krabben spelen daarbij een grote rol.\r\n\r\nRIVO = voorjaar, MWTL = najaar","Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":"Dutch","EmbargoDate":null,"OrigDescrLangNL":"Nederlands","OrigLangCode":"nl","OrigLangCodeExtended":"dut","OrigLangID":41,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":null,"AccessConstraints":null,"UDate":"2010-07-19","CDate":"2010-01-25","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-30 01:37:59.451226","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":0,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":0,"FreshFlag":0,"BrackishFlag":1,"TerrestrialFlag":0,"StatusID":1,"DasType":"Static graphs","DasTypeID":18,"DasOrigin":null,"Progress":null,"AccessConstraint":null,"AccConstrEN":null,"AccConstrDisplay":null,"License":null,"AccConstrDescription":null,"Lineage":null,"AccConID":null},"dois":null,"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"}],"keywords":[{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Biomass","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_926","Description":null,"OrigThesTerm":"Biomass","DutchTerm":"Biomassa","URI":"http://aims.fao.org/aos/agrovoc/c_926","DasKeywordDescr":null},{"ThesaurusTerm":"Cockles","ThesTypID":2,"ThesType":"CSA Technology Research Database Master Thesaurus","Code":null,"Description":null,"OrigThesTerm":"Cockles","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Relative","ThesTypID":2,"ThesType":"CSA Technology Research Database Master Thesaurus","Code":null,"Description":null,"OrigThesTerm":"Relative","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Size","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_7093","Description":null,"OrigThesTerm":"Size","DutchTerm":"Grootte","URI":"http://aims.fao.org/aos/agrovoc/c_7093","DasKeywordDescr":null}],"parents":null,"children":null,"othrel":null,"othrelrev":null,"ownerships":[{"OrderNr":1,"Surname":"van Eck","Firstname":"Bert","Initials":"G.T.M.","PerPublicFlag":1,"AdrID":null,"Email":null,"InsPublicFlag":1,"Acronym":"DELTARES-VEB","OrigNameLangCode":"nl","OrigNameLangID":41,"FullOrigName":"Deltares;
