چکیده مقاله :
زمینه و هدف: در سال‌های اخیر احداث مزارع پرورش ماهیان سرد آبی در کنار رودخانه‌ها افزایش یافته و تخلیه پساب این مزارع بدون هیچ تصفیه‌ایی به زیستگاه‌های طبیعی می تواند آثار سو و مخربی به دنبال داشته باشد. از جمله مهم‌ترین جوامع حیاتی رودخانه‌ها، بزرگ بی‌مهرگان می‌باشند که قادرند به عنوان یک شاخص زیستی تغییرات کیفیت آب را نشان دهند. هدف از این مطالعه بررسی تأثیر پساب تصفیه نشده مزارع پرورش ماهی بر روی بزرگ بی‌مهرگان کف زی نهر زرین گل می باشد.روش بررسی: در مطالعه حاضر کیفیت آب با استفاده از شاخص‌های زیستی در رودخانه زرین گل، استان گلستان در فصل زمستان 1394 و بهار 1395 در 4 ایستگاه و ماهیانه (در موقعیت‌های ورودی، خروجی و 500 و 1000 متر پایین‌دست مزرعه پرورش ماهی) با نمونه‌برداری با سوربرسمپلر سطح 09/0 مترمربع در سه تکرار صورت گرفت. نمونه‌ها توسط فرمالین 4% تثبیت و در آزمایشگاه جداسازی، شناسایی و شمارش گردید.یافته‌ها: افزایش فعالیت‌های انسانی از جمله وجود مزارع پرورش ماهی در این منطقه می‌تواند موجب آلودگی آب‌های سطحی این رودخانه شده است. در مجموع 2179 نمونه از بزرگ بی‌مهرگان کف زی شناسایی شدند که به 35 جنس، 28 خانواده و 9 راسته تعلق داشتند. فراوانی این موجودات به ترتیب مربوط به راسته Diptera با 9/46 درصد، Ephemeroptera با 7/27 درصد، Trichoptera با 9/16 درصد و Lmbricida با 31/2 درصد و بقیه 19/6 درصد بوده است.بحث و نتیجه‌گیری: نتایج نشان داد که شاخص‌های شانون، تشابه توزیع، TBI، IBI و IRWQISC نشانگر مناسب بودن برای ارزیابی کیفت آب در ایستگاه‌های مطالعاتی می‌باشد. به طور کلی، کیفیت آب در محدوده مطالعاتی به جز ایستگاه 2 (بعد استخر پرورش ماهی) بر اساس شاخص‌های محاسباتی مطلوب ارزیابی گردید که بیانگر لزوم اعمال مدیریتی مناسب به منظور بهبود کیفیت آب این منطقه می‌باشد.
Background and Objective: Due to increasing population and demand for aquatic products and protein, in recent years the construction of fish farms, especially cold-water fish farms along the rivers has increased, and the effluent discharge of these farms without any treatment to the natural habitats of adverse and destructive effects. Eating the natural balance of the water will help the ecosystems. Among the most important communities of rivers and streams are large invertebrates. These organisms are able to represent water quality changes as a biological indicator. The purpose of this study was to investigate the effect of untreated effluent of fish farms on large invertebrates of Zarrin Ghee brook, because the inflow of these effluents into streams and rivers affects the structure and composition of streams, causing disruption of ecological balance. Method: In the present study large biodiversity of aquatic invertebrates as well as water quality using biomarkers in Zarrin River, Golestan province in winter 2015 and spring 1395 m2 at 4 stations and monthly (at entry, exit and 500 and 1000 m downstream farm) Fish breeding) was done by sampling with a Surface bumper level of 0.09 m 2 in three replications. Samples were fixed with 4% formalin and isolated, counted and counted in the laboratory. Findings: Increased human activities, including the presence of fish farms in the area, can contaminate the surface water of the river. A total of 2179 specimens of large benthic invertebrates were identified, belonging to 35 genera, 28 families and 9 orders. Frequency of these organisms, were respectively Diptera with 46.9%, Ephemeroptera with 27.7%, Trichoptera with 16.9% and Lmbricida with 2.31% and the rest with 6.19%. Discussion and Conclusion: The result sowed that Shannon diversity, Evenness, TBI, IBI and IRWQISC were good indicators for water quality assessment in the study stations. In general, water quality in study area except station 2 (after fish farm) was desirable that the necessity of efficient water management to improve water quality in this region.
