There is a large body of evidence that n-3 fatty acids, especially EPA and DHA are beneficial for human health. Content of these fatty acids in fish fillet can be influenced by several factors. This thesis examined differences in lipid content, lipid class and fatty acid composition among three parts of common carp fillets. The effect of genetic background on lipid content and fatty acid compos...
lipids play an important role in maintaining human health. thermal process cause to changes in nutritional value as well as changes in the profile of fatty acids in fish. the aim of this study was to evaluate the effect of frying on chemical composition and profile of fatty acids is fish shaary. for doing this project, 10 kg of the fish were purchased from the market of behbahan and with ice we...
Ornamental fish production, like all other segments of aquaculture, relies heavily on the successful spawning, hatching, and survival of larvae. Little is known about the nutrient requirements of most ornamental fish species. In many cultivars of fishes, such as Ornamental fish, especially in those new Ornamental fish species introduced to the aquaculture industry, the rate of fecundity is an i...
اثر ترکیبی مقادیرمختلف اسیدهای چرب ضروری امگا 3hufa (dha, c22:6n-3 و epa, c20:5n-3) وویتامین eجیره بر شاخص های رشد (وزن نهایی، ضریب رشد ویژه و ضریب تبدیل غذایی) و برخی از شاخص های فیزیولوژیک (هماتوکریت، میزان چربی ها و لیپوپروتئین های پلاسما)، در بچه ماهی نورس ماهی آزاد دریای خزر(salmo trutta caspius) بررسی شد. ابتدا شش جیره با سه مقدار مختلف از اسیدهای چرب امگا 3dha) و epa) به نسبت 1 به 0/...
Microalgae nutritional value during the larviculture has many important roles can be affected on increasing quantity and quality production. The deficiency of some fatty acids especially HUFA in formulation feed which is normally used in aquaculture, is one of the most important problem in feeding, which using the marine sources oil can solve that. In this study, standard method used in culture...
در این تحقیق ، تحمل شوری در لارو تاسماهی ایرانی تغذیه شده با ناپلیوس آرتمیا ارومیانا غنی شده با hufa و ویتامین c ، با در معرض قرار دادن آنها در شوری های مختلف، مورد بررسی قرار گرفت. برای این منظور سیست آرتمیا ارومیانا در شرایط استاندارد تفریخ و توسط امولسیون تجاری همراه با سه سطح 10، 20 و 30 درصد ویتامین cهر کدام با سه تکرار غنی و به مدت 20 روز لارو تاسماهی ایرانی با آنها تغذیه شدند. گروه کنترل...
Rainbow trout is one of the most important cultured species in Iran. Despite the progressively increased production of this species during the last decade, there have been many egg quality problems in the hatcheries yet. Thus, in this research we investigated the effects of adding Artemia powder to broodstock diet on Rainbow trout egg quality. Fishes were fed commercial diet for four months, th...
Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...
This study was undertaken to investigate the effects of feeding rainbow trout (Oncorhynchus mykiss) broodstocks with different ratio of plant oils to evaluate the changes in antioxidant defense status in the progenies. In the experimental diets, fish oil was replaced with different combination of plant oils including corn oil, olive oil, sunflower oil, and coconut oil, to gain differen...
