The results of the research showed that the total fertility of mature females of the\u00a0 <em>Trachurus trachurus<\/em> fish amounted to 110208\/ eggs in the Ras Albasit area and 94535\/ eggs in the Burj Islam area, with lengths ranging from 16.2 \u2013 22.2 cm. The results of the study of changes in the values of the Sexual maturity coefficient (GSA%) indicated that the sexual cycle lasts for a whole year, but the laying of eggs occurred in the form of batches. The peak value of the maturity coefficient was reached in the regions of Ras Al basit and Burj Islam during the month of May, and females lay their eggs for the first time when average lengths of 16.4 cm. The statistical study also showed that there were significant differences (p &gt; 0,05) in the mean values of the liver weight index (HSI%) between females and males in both study areas.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\"><strong>Keywords: <\/strong>Reproductive biology, Fertility, <em>Trachurus trachurus<\/em>, Syrian marine water.<\/span><\/p>\n<p><span style=\"font-family: 'Times New Roman', Times; font-size: 17px;\">Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/v9n5p15.pdf\">pdf<\/a><\/span><\/p>\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ranim Othman* (1), Mohamad Galiya(1), and Zohair Almajed \u00a0(1) (1).
