| چکیده در تحقیق حاضر اثرات شوری آب بر عملکرد رشد و تغذیه و فاکتورهای بیوشیمیایی خون ماهیان قزل‌آلای رنگین‌کمان (Oncorhynchus mykiss) پیش‌پرواری با وزن اولیه 11/4±22/93 گرم به مدت 60 روز بررسی شد. پس از 10 روز سازگاری به شوری آب، 450 قطعه ماهی در قالب یک طرح کاملاً تصادفی در 5 تیمار و 3 تکرار توزیع شدند. شاخص‌های رشد، تغذیه و برخی فاکتورهای بیوشیمیایی خون، قبل از مرحله سازش‌پذیری به آب شور و 1، 10، 25 و 50 روز پس از معرفی به شوری‌های مختلف (صفر ،40،30،20،10 گرم در لیتر) مورد بررسی قرار گرفت. براساس نتایج حاصل از این تحقیق با افزایش میزان شوری آب تا 20 گرم در لیتر شاخص‌های رشد و تغذیه شامل میزان رشد روزانه، ضریب رشد ویژه و بازده تبدیل غذا به صورت معنی‌داری کاهش یافت (05/0>P) و شوری‌های بالاتر (30 و 40 گرم در لیتر) به تلفات دسته جمعی منجر شد. در طول آزمایش، فاکتورهای بیوشیمیایی خون شامل اسمولاریته، کورتیزول، کلرینیتی، گلوکز، تری یدو تیرونین و تیروکسین خون با افزایش میزان شوری به صورت معنی‌داری افزایش یافت (05/0>P) .به طور کلی، نتایج به دست آمده نشان می‌دهد که ماهی قزل‌آلا رنگین‌کمان با وزن اولیه 90 گرم می‌تواند، در آب‌هایی با شوری حدود 20 گرم در لیتر به صورت موفقیت‌آمیز پرورش یابد، اگرچه میزان رشد در این شرایط کمتر از آب شیرین است. | ||

| چکیده [English] | ||
| At the present work, effects of salinity were studied on growth and feeding performance, survival rate and blood biochemical parameters of pre on-growing rainbow trout (Oncorhynchus mykiss) with initial weight 93.22±4.11 g for 60 days. After adaptation to water salinity for 10 days, 450 fish were distributed in 5 treatments and 3 replicates according to a complete randomized design. Before adaptation to water salinity 1, 10, 25 and 50 days after introduction to a different salinity with in (10, 20, 30 and 40 ppt), growth and feeding parameters and some blood biochemical parameters were investigated. According to the obtained results of study, increase salinity up to 20 ppt, growth and feeding parameters significantly decreased including daily growth rate, specific growth rate, feed conversion efficiency between salinity groups and control group (P<0/05) and higher salinities (30 and 40 ppt), caused gregarious mortality. During the experiment, blood biochemistry parameters including osmolality, chlorine, sugar, cortisol, tri-iodo thyronin(T3), and Tetra–iodo–thyronin (T4) significantly increased with increasing water salinity (P<0/05). Overall, the obtained results indicated that rainbow trout with initial weighing 90 g, could be cultured successfully in water with salinity up to 20 ppt, although fish growth rate is lower than that in the fresh water. | ||
