| چکیده هدف از انجام این مطالعه، بررسی ترکیب و تعیین صید بهازای واحد تلاش بیمهرگان در تور ترال میگو در فصل صید سال 1394 بود که در آبهای ساحلی استان هرمزگان در دو منطقه (سواحل بندرعباس و جزیره هرمز) و در اعماق کمتر از 10 متر، 20-10 متر و بیشتر از 20 متر انجام شد. تعداد تورکشیها 40 مرتبه و مدت زمان هر تورکشی تقریباً 2 الی 5/2 ساعت بود. صید بهدستآمده به میزان 7623 کیلوگرم در کل نمونهبرداری شامل 1068 کیلوگرم میگوی تجارتی و 6555 کیلوگرم صید ضمنی شامل بیمهرگان (8/2386 کیلوگرم) و ماهیان (2/4168 کیلوگرم) بود. ترکیب صید شامل میگو 14%، بیمهرگان31% و ماهیان 55% بود. نتایج نشان داد، اثر تغییرات منطقه و اعماق مختلف و همچنین اثر متقابل منطقه و عمق بر صید به ازای واحد تلاش در کل صید، صید هدف (میگو)، میگوی مانتیس (Oratosquilla oratoria)، خرچنگ آبی (Portunus pelagicus)، خرچنگ ریز (Crustacea)، ماهی مرکب ببری (Sepia pharaonis)، مرجان (Anthozoa)، اسفنج دریایی(Demospongiae)، عروس دریایی (Rhizostomatidae)، ستاره دریایی (Asteroidea) و هشتپا (Octopoda) اختلاف معنیدار بوده است. در مجموع 40 مرتبه تورکشی در هر دو منطقه، میگوی مانتیس، عروس دریایی و ماهی مرکب بیشترین و اسفنج کمترین درصد وقوع صید را نشان دادند. | ||

| Abstract The aim of this study was to investigate catch composition and catch per unit effort of invertebrates in shrimp trawl in different areas and depths. This research was carried out in Hormozgan coastal waters (Bandar Abbas and Hormuz Island) at depths of less than 10 meters, 10-20 meters and over 20 meters in shrimp fishing season in 2015. 40 hauls that duration of each one was approximately 2 to 2.5 hours with a total catch of 7623 kg were done. The catch composition included 1068 kg of commercial shrimp and 6555 kg of by-catch that included invertebrates and fish which were 2386.8 and 4168.2 kg, respectively. The results showed that the catch composition consisted of 14% shrimp (1068 kg), 31% by-catch invertebrates (6555 kg) and 55% by-catch fish (4168.2 kg). There were significant differences among the CPUE in the different areas and depths as well as the interaction of area and depth on CPUE of the total catch, target species (Shrimp), Oratosquilla oratoria, Portunus pelagicus, Crustacea (Small crab), Sepia pharaonis, Anthozoa, Demospongiae, Rhizostomatidae (Jelly fish), Asteroidea and Octopoda (POratosquilla oratoria, Rhizostomatidae and Sepia pharaonis and the Demospongiae was at the least. | ||
