Abstract :
اين مطالعه به شناسايي 5 گونه فيله ماهي داخلي عمل آوري شده مورد مصرف در بازار ايران پرداخت. اين تحقيق با بكارگيري تكنيك DNA باركدينگ و استفاده از ژن سيتوكروم اكسيداز (زيرواحد شماره1) به جهت راستي آزمايي گونه‌ها صورت پذيرفت. بر اساس نتايج بدست آمده نام درج شده بر روي فيله ماهي شير اشتباه بوده و از فيله ماهي قباد در آن استفاده شده كه با توجه به تعداد نمونه‌ها مي‌توان 11 درصد محصولات را تقلبي دانست.
Abstract :
This study reports on the molecular identification of fish species from processed products which had a priori been classified as belonging to 5 important species in Iran for human consumption. DNA barcoding using direct sequencing of an approximately 650bp of mitochondrial Cytochrome oxidase subunit I (COI) gene revealed incorrect labeling of Narrow-barred Spanish mackerel samples. High occurrence of fraudulent fishery products, if left unchecked, can pose a negative impact on the economy. This investigation adds further concern on the trading of processed fish products in Iran from both health and conservation points of view.
