چکیده

این تحقیق در  دوره زمانی سال های 1397-1386 و در محدوده صیدگاه ها و مراکز تخلیه صید استان های جنوبی کشور با استفاده از داده های سری زمانی صید در واحد تلاش سفره ماهیان اجرا گردید. بر همین اساس  داده های محیطی شامل درجه حرارت سطحی دریا، کلروفیل a ، تبخیر، بارندگی، سرعت باد و درجه حرارت هوا استخراج و مورد بررسی قرار گرفت. به منظور تعیین روابط میزان صید سفره ماهیان با شرایط اکولوژیک،  از روش های رگرسیون، شبکه عصبی و درخت تصمیم استفاده گردید. نتایج به دست آمده نشان داده است که  میزان ذخیره در چهار استان خوزستان، بوشهر، هرمزگان و سیستان و بلوچستان روند متفاوتی داشته است. به طوری که ذخیره سفره ماهیان در آب های استان خوزستان با سرعت باد و درجه حرارت سطحی دریا، در آب های استان بوشهر با میزان کلروفیل a، در آب های استان هرمزگان با درجه حرارت هوا و در آب های استان سیستان و بلوچستان با درجه حرارت سطحی آب رابطه معنی داری داشته است. از بین عوامل ذکر شده دو عامل درجه حرارت هوا  و سطحی  دریا و در چهار استان افزایش نشان داده است. نتایج این تحقیق نشان می داد که تاثیر عوامل اقلیمی بر ذخایر سفره ماهیان در هر یک از نواحی ساحلی – دریایی استان های جنوبی کشور متفاوت می باشد.

چکیده [English]

This study conducted to analyses time series data of stingrays catch per unit effort (CPUE (kg/day) data from 2007 to 2018 from fishing grounds of the Persian Gulf and the Oman Gulf. Data from sea surface temperature, chlorophyll a, evaporation, wind speed, rainfall and air temperature were also considered in the analysis. In order to investigate ecological status, regression models, neural networks and decision tree used to analyses data. According to the results, biomass of the stingrays stock showed different status in various parts of the water body and results revealed that stingrays stock significantly related with wind speed and sea surface water in Khuzestan waters, chlorophyll a in Bushehr waters, air temperature in Hormozgan waters and sea surface temperature in Sistan and Balouchestan waters. Technically, temperature was the constant significant coefficient in all parts of the study area. To sum up, effect of climate change on stingray’s biomass was sensible according to the results of this study and was vary between study sites.
