| ارزش اقتصادی ماهیان با ارزش صید ورزشی مانند آزاد ماهی خزر (Salmo caspius, K. 1877)، بر اساس برآورد مقدار پولی که ماهی‌گیران برای صید ماهی تمایل به پرداخت دارند، تعیین میشود. هدف از انجام این تحقیق برآورد تمایل به پرداخت ماهی‌گیران با قلاب برای حفاظت از گونه در خطر انقراض آزاد ماهی خزر، بهمنظور تعیین ارزش حفاظتی این گونه منحصربهفرد است. در راستای انجام این تحقیق، طی سالهای 1399-1397 تعداد 444 نفر از ماهی‌گیران با قلاب به روش نمونهگیری تصادفی انتخاب و مورد پرسش قرار گرفتند. ابزار گردآوری دادهها، پرسشنامهای محقق ساخته شامل؛ مشخصات جمعیت‌شناسی و سوالات ارزیابی تمایل به پرداخت ماهی‌گیران برای حمایت از آزاد ماهی دریای خزر بود. پس از جمعآوری دادهها، نتایج با استفاده از الگوی کیفی لوجیت و بهرهگیری از روش حداکثر راست‌نمایی، با کاربرد نرمافزارهای SPSS نسخه 21 و اقتصاد سنجی Eviews نسخه 10، تجزیه و تحلیل شدند. یافتههای پژوهش نشان داد که، 75% از افراد مورد مطالعه، تمایل به پرداخت مبلغی برای حمایت از این گونه در خطر انقراض دارند. ارزش حفاظتی ماهیانه و سالیانه گونه در خطر انقراض آزاد ماهی خزر، بر اساس متوسط تمایل به پرداخت محاسبه شده، به ترتیب معادل با 2/1979 و 4/2375 میلیون ریال برآورد شد که از جریمه صید غیرقانونی این گونه (5/120میلیون ریال) بسیار بیشتر است. بر اساس نتایج این پژوهش، متغیرهای تحصیلات، درآمد، اشتغال، عضویت در سازمانهای مردم نهاد زیست‌محیطی، شناخت گونه و میزان پیشنهاد از عوامل مثبت تأثیرگذار بر میزان تمایل به پرداخت برای حمایت از گونه در خطر انقراض آزاد ماهی خزر است. | ||

| چکیده [English] | ||
| The economic value of the sport fishing valuable species such as Caspian brown trout (Salmo caspius, Kessler, 1877), is estimated based on the determination of the amount of money that fishermen tends to pay for fish catching. The aim of this research was to estimate the willingness to pay (WTP) of anglers to the conservation of the endangered Caspian brown trout, in order to determine the conservation value of Caspian brown trout. In order to do this research, from 2018 to 2020, 444 anglers were selected by random sampling method. Data gathering tool was a researcher-made questionnaire comprising items about the angling demographic characteristics as well as their WTP for the protection of the endangered species of Caspian trout. Eventually, analysis of gathering data was carried out with applying a Logit model under maximum likelihood procedure by using SPSS (version 21) and Eviews (10) Software. The result showed that 75 percent of the anglers had a positive WTP for the protection of the endangered species of Caspian trout. The average payment of WTP for the monthly and annual protection value of Caspian trout was estimated 1979.2 and 23750.4 million RLs respectively, which is much higher than that of the penalty for illegal fishing (120.5 million RLs). According to the results of this research, the variables of the literacy level, income, job, membership in the environmental organization, species recognition and bid have positive effects on the WTP for the protection of endangered species of Caspian trout. | ||
