چکیده

شناخت و بررسی منابع آب‌های سطحی به ویژه رودخانه‌ها و نهرها که در واقع جز منابع استراتژیک محسوب می‌شوند، به منظور اعمال مدیریت بهیته، از اهمیت زیادی برخوردارند. بدین منظور تاثیر کارگاه پرورش ماهی قزل‌آلای رنگین‌کمان بر روی فون و تعداد ماکروبنتوزها (Macro-benthose) در رودخانه هراز بررسی شد. در این تحقیق نمونه‌برداری در رودخانه هراز در دو فصل تابستان و پاییز 1393 به وسیله دستگاه Surber Sampler، در مجموع 4 ایستگاه از قبل تا بعد از مزرعه پرورش ماهی و با سه تکرار در هر ایستگاه انجام گرفت. در آزمایشگاه گروه‌‌های کفزیان بصورت کیفی وکمی در حد جنس یا گونه مورد بررسی قرار گرفتند. نتایج بررسی حضور 11 رده یا راسته ماکرو‌بنتوزی متعلق به 19 خانواده را نشان داده است. بیشترین جنس مربوط به خانوادهDiptera با 9 جنس بوده و 13 جنس نیز از سایر رده‌ها شناسایی گردید. بررسی نمونه‌ها نشان داد بیشترین درصد فراوانی مربوط به خانواده Baetidae از راسته یا رده Ephemeroptera دیده شد.بیشترین تاثیر آلودگی کارگاه‌ها بر روی 3 راسته‌ی Ephemeropterta، Terichoptera و Plecoptera بود که به گروه حساس EPT معروف بوده و باعث کاهش جمعیت آن‌ها در ایستگاه 3 (خروجی) شده است. برعکس، جمعیت خانواده شیرونومیده (Chironomidae) که بی‌مهرگان کفزی مقاوم به آلودگی هستند، افزایش پیدا کرده بود.

چکیده [English]

Recognizing and investigating the resources of surface water, especially rivers and streams, which are in fact not just strategic sources, are important for the management of well-being. For this purpose, the effect of rainbow trout breeding workshop on the fauna and the number of macro-benthos in the river Haraz were investigated . Sampling was performed seasonally in two seasons of summer and autumn of 1393 by Surber Sampler with three replications at each station. A total of 4 stations were set up before and after the fish breeding farm. In the laboratory, cluster bands were examined qualitatively and quantitatively in the genus or species. The results of the study showed the presence of 11 classes or macrobenthic sequences belonging to 19 families. Most of the genus was Diptera family with 9 genera and 13 genera were identified from other classes. Sampling showed that the highest percentage of Baetidae family was found in Ephemeroptera.
The biggest impact of workshop pollution was on Ephemeropterta, Terichoptera and Plecoptera, which is known as the sensitive group of EPT and has reduced its population at station 3 (outlet). On the contrary, the population of the Chironomidae, which is resistant to pollution, has increased.
