The reproductive cycle was monitored for a period of two years, from January 2013 to December 2014. Spawning extended from June to October, with a peak in the summer months (July to September). The condition index showed a seasonal pattern which appear related to food availability and gametogenic cycle. Sexual maturity was attained at a shell length of 18.6&nbsp;mm during the first year of life, which stands below the minimum landing size currently in force (25&nbsp;mm). The von Bertalanffy growth equation was based on size-at-age data obtained from the microscopic analysis of growth-rings in sectioned shells: L</span><sub>t</sub>&nbsp;=&nbsp;40.7[1-e <sup>−0.74(t-0.30)</sup><span>]. The morphometric relationships between shell dimensions (length, height and width) were studied in order to understand the effects of ontogenetic changes in cockles` shell morphology, an information that is useful to improve the selectivity\" title selectivity of the fishing gears and the size-sorting devices. Some management strategies for the Ria de Aveiro cockle fishery were proposed.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Biology of the common cockle <i>Cerastoderma edule</i> (Linnaeus, 1758) in Ria de Aveiro (NW Portugal): Implications for fisheries management","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-16 01:33:26.157296","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Common cockle; Condition index; Size at first maturity; Growth and morphometry;  Fishing management proposals","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2021-07-05","DateCreate":"2021-07-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000644223700003","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.seares.2021.102024"},"refs":null,"anarec":{"AnaID":339641,"PubliDate":2021,"Pagination":"102024","XtraPublOfAnaID":null,"ISBN":null,"Volume":"171","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
