Abstract AR
اجريت الدراسة لاجل التعرف على دورة التكاثر لاسماك الخشني Liza abu في نهر دجلة (جنوب بغداد).
اصطيد 439 ذكر و 524 انثى لمدة سنتين و الاصطياد كان اسبوعيا، شرحت الاسماك مباشرة و اخذت القياسات البيولوجية.
حددت ست مراحل للتكاثر للذكور و الاناث سميت: الراحة، النضج، ما قبل السرء المبكرة، ما قبل السرء المتقدمة، السرء، و ما بعد السرء.
تراوحت دالة المناسل للذكور بين 0.
27- 9.
74 في ايلول الى اذار و كانت للاناث بين 0.
94-13.
35 في تشرين الاول الى نيسان على التوالي.
حدث السرء في الفترة بين ايار الى تموز عندما وصلت درجة حرارة الماء الى 24.
7- 28.
9 م ̊.
خلصت الدراسة الى ان اسماك الخشني في نهر دجلة لها دورة تكاثر كاملة تقع في ست مراحل لكلا الجنسين، وان السرء يحدث في ثلاثة اشهر هي ايار- تموز عندما ترتفع درجة حرارة ماء النهر معنويا الى 24.

This study was conducted to investigate the reproductive cycle of Khishni fish, Liza abu in Tigris River (Southern Baghdad).
A total of 439 male and 524 female khishni were captured for two years and the capturing was weekly, immediately dissected for general biological parameters.
Six reproductive stages have been distinguished for both male and female and were termed as; resting, maturing, early pre spawning, advance pre spawning, spawning and post spawning.
Male GSI ranged between 0.
27 to 9.
74 in Sep.

, and for female it was 0.
94 to 13.
35 in October to April respectively.
