Alternative Title
Reproduction cycle and fecundity study of Liza aurata (Risso, 1810) in Tartous (Syria) coastal waters
دراسة دورة التكاثر والخصوبة في سمك البوري دهبان (Risso, 1810)
Abstract
L’étude de la biologie de 852 poissons de Liza aurata dans les eaux côtières de Tartous a montré que la période de reproduction de cette espèce se situe durant octobre-novembre. La taille à la première maturité est de l’ordre de 34 cm (Lt) pour les femelles âgées de 3 ans. La fécondité absolue augmente avec la taille de poisson.
لقد بينت دراسة تطور الغدد التناسلية ل 852 فردا من إناث وذكور سمك البوري دهبان خلال 13 شهر إن فترة التكاثر لهذا النوع تقع خلال تشرين أول وتشرين ثاني، كما أظهرت هذه الدراسة أن الخصوبة المطلقة تزداد بازدياد طول الجسم. من ناحية أخرى بينت النتائج أن الإناث تدخل في مرحلة أول نضوج جنسي عندما يصل طولها الكلي ل34 صم وبعمر 3 سنوات،بينما تدخل الذكور في نفس المرحلة عندما يصل طولها الكلي ل 30 صم وبعمر سنتين.
Biological studies of 852 fishes species liza aurata in Tartous coastal waters showed that it’s reproductive cycle occurs during the period October -November. The first maturity size is about 34 cm (Lt) for females of 3 years age and 30 cm (Lt) for males of 2 years. The absolute fecundity increases with age of fishes.
