The study was conducted over 2\u2009years, from May to October, coinciding with the period when the local gillnet fishery targets surmullet\n                    <jats:italic>Mullus surmuletus<\/jats:italic>\n                    . The timing of reproduction was examined by the gonado\u2010somatic index, the macroscopic assessment of the ovarian stage, and the microscopic examination of the ovarian developmental stage. All three indices demonstrated that spawning\u2010capable females were caught in May and June and that spawning ceases by late July to August. Regarding spawning dynamics, the European barracuda is a multiple spawner; the oocyte size frequency distributions of all spawning\u2010capable and actively spawning females were continuous, and postovulatory follicle cohorts from different daily spawning events co\u2010occurred in the ovaries of many of those females. Relative batch fecundity was rounded off to 197\u2009\u00b1\u2009108 oocytes per\u2009gram and relative total fecundity at 1263\u2009\u00b1\u2009513 oocytes per gram. The somatic condition increased in postspawning individuals, suggesting a capital breeding reproductive strategy.\n                  <\/jats:p>","DOI":"10.1111\/jfb.16070","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T22:24:56Z","timestamp":1738621496000},"page":"1809-1815","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reproductive timing and spawning dynamics of European barracuda\n                    <scp>\n                      <i>Sphyraena sphyraena<\/i>\n                    <\/scp>\n                    in eastern Mediterranean Sea"],"prefix":"10.1111","volume":"106","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3050-0877","authenticated-orcid":false,"given":"Foivos A.","family":"Mouchlianitis","sequence":"first","affiliation":[{"name":"School of Biology Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katerina","family":"Charitonidou","sequence":"additional","affiliation":[{"name":"Institute of Marine and Antarctic Studies University of Tasmania  Hobart Tasmania Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Tsavdari","sequence":"additional","affiliation":[{"name":"School of Biology Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Minos","sequence":"additional","affiliation":[{"name":"School of Health Science, Department of Nursing International Hellenic University  Thessaloniki Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kostas","family":"Ganias","sequence":"additional","affiliation":[{"name":"School of Biology Aristotle University of Thessaloniki  Thessaloniki Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,2,3]]},"reference":[{"key":"e_1_2_9_2_1","first-page":"255","article-title":"Reproductive biology of Sphyraena species in the Egyptian Mediterranean waters off Alexandria","volume":"30","author":"Allam S.
