Abstract AR
قيمت بيئة تجمع أسماك هور شرق الحمار للفترة من تشرين الأول 2005 و لغاية أيلول 2006 باستخدام دليل التكامل الحياتي Integrated Biological Index (IBI).
تم انتخاب 16وحدة لقياس دليل التكامل الحياتي اعتمادا على غنى و تركيبة و طبيعة غذاء أنواع تجمع الأسماك.
كانت حالة تجمع أسماك هور شرق الحمار مقبول IBI = 42.6 %)) خلال عام2006-2005 ، أي بعد السنتين الأولى من فعاليات إعادة المياه و تحسن نوعيته و هي أفضل من حالة الهور بعد مضي أربعة سنوات من ذلك، إذ بلغت قيمة IBI خلال عام (% 40.8) 2008-2007 .
يتبين من النتائج عدم حصول تحسن جوهري في حالة الهور خلال السنين الأخيرة مما يعكس بان البيئة لازالت هشة و تتطلب وقتا لاستعادة حالتها الطبيعية.
Abstract EN
An Index of Biotic Integrity (IBI) was used to assess the status of the fish assemblage of east Hammar marsh from October 2005 to September 2006.
IBI scores were calculated from 16 separate assemblage metrics based on the species richness, species composition and trophic guilds.
After more than two years of restoration activities and improved water quality, the state of the fish community in Hammar marsh was fair during 2005-2006 (IBI = 42.6 %), and better than the same study marsh after four years of restoration (IBI = 40.8 %).
The results revealed that no substantial improvements have been recorded during the late years of restoration, reflect that the environment is still fragile and need time to be recovering.
