Marginal increment and edge analyses suggest annual band pair formation. The oldest female and male brown rays were 9 and 7 years old, respectively. Von Bertalanffy growth parameters are <i>L</i>8 = 69.20 cm TL, <i>k</i>=0.18 year<sup>–1</sup> and <i>t</i> <sub>0</sub>=–0.11 years for females, and <i>L</i>8 = 67 cm TL, <i>k</i>=0.22 year<sup>–1</sup> and <i>t</i> <sub>0</sub>=–1.01 years for males. Longevity estimates were 19.25 and 15.75 years for females and males, respectively. Based on life history parameters, natural mortality estimation <i>M</i> was in the range 0.37–0.47 for females and 0.60–0.61 for males. Males were found to mature between 28 and 43 cm TL and L<sub>50%</sub> was estimated at 34.31 cm TL (21.91 cm DW). Females mature between 33 and 48 cm TL and reached L<sub>50%</sub> at 41.8 cm (27.10 cm DW). Age at sexual maturity (A<sub>50%</sub>) was estimated at 2.7 years for males and 4.41 years for females. Females and males have an annual reproductive cycle. Mating occurred mostly through spring and summer.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Age, growth and reproduction of <i>Raja miraletus</i> (Linnaeus, 1758) (Chondrichthyes: Rajidae) of the Gulf of Gabès (Tunisia, Central Mediterranean Sea)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Age; growth; Gulf of Gabes (Tunisia); longevity; maturity; MediterraneanSea; natural mortality; Raja miraletus","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2012-04-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000302439700009","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000.2011.619546"},"refs":null,"anarec":{"AnaID":214269,"PubliDate":2012,"Pagination":"388-396","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
