Abstract AR
اجريت هذه الدراسة في مفرخ تجاري بشكشوك - محافظة الفيوم بداية 6/5/2005 واستمرت لمدة 122 يوم .
استخدم فيها 105 ام و 35 ذكر بلطي نيلي عمرها عام و بمتوسط وزن 170-175 جم لكل هابة (4 * 7 م ) ، استخدم خمس نظم غذائية (0.5 ، 1.0 ، 1.5 ، 2.0 و 3.0 % من وزن الام/يوم) مكونة 5 معاملات .
تم جمع البيض و اليرقات بداية من 27/5/2005 كل 10 ايام وتم الحصول على بيانات الاداء التناسلي و النمو وتم عمل تقييم اقتصادي .
اظهرت النتائج ان احسن اداء تناسلي و اقتصادي كان مع معدل التغذية 1% مظهره ادائ نمو افضل و كذلك من الناحية الاقتصادية ، وكان معدل التغذية 0.5% اقل منه بفارق طفيف مقارنة بمعدلات التغذية الاخرى العالية و التي لا يوصى بها .
Abstract EN
The present work was conducted in commercial hatchery at Shakshouk, Fayoum Governorate.
The trial started at 6 / 5 / 2005 and lasted for 122 days.
A number of 105 females and 35 males of one year old broodfish weighing 170 to 175 g in average were used per hapa.
Five feeding regimes were used (0.5, 1.0, 1.5, 2.0 and 3.0 % of broodfish body mass / day) forming 5 treatments (regimes).
Seeds were collected at 10 day intervals starting from 28 /5 / 2005.
Data obtained were on reproductive performance, growth performance and economic evaluation.
Data revealed that the 1 % feeding rate showed better reproductive performance and economic evaluation.
The 0.5 % feeding rate tended to show slightly lower values.
The other higher levels of feeding were not recommended.
