The aim of the present study was to investigate the reproduction of three species of kilka, including common, anchovy and bigeye kilka in the southeastern waters of Caspian Sea. This study was conducted during 2010 and 6476 specimens were fortnightly collected from fishing landing site. Body weight and fork length were measured. The samples were dissected and female gonads were weighed. Sexual ...
در این تحقیق 9 عدد شگ ماهی (Alosa caspia caspia)دریای مازندران در اسفند 1388 صید و جهت مطالعه انتخاب شد. هدف شناسایی اسیدهای چرب و اثر آنتی اکسیدان ویتامینC وبستهبندی وکیوم و انجماد بر روی تغییرات اسیدهای چرب در زمان نگهداری در سردخانه با دمای 18ـ درجه سانتیگراد طی 120 روز بود. نتایج نشان داد که در نمونه حاوی ویتامین C غلظت 5 در صد نسبت به 1درصد تغییرات کمتری وجود دارد. مجموع اسیدهای چرب اشب...
Three species of kilka (Clupeonella spp.) in the Caspian Sea have a high commercial value. In Iran it is use to produce canned, marinated packs and paste in making sausage and nugget. Kilka is a nutritious fish with high level of iron and considerable level of polyunsaturated fatty acids making it prone to auto-oxidation. The quality of kilka is the most important factor affects on its products...
The aim of this work was to study the effect of sodium chloride replacement with potassium chloride on quality changes of hot smoked Kilka during storage at ± 4°C. To achieve this, after initial preparation, samples were exposed to brining process in two salts. This study was designed in two stages: in the first stage, different levels of salt replacement were used to select the best...
Physicochemical properties of surimi and kamaboko obtained of solubility in acid, alkaline and conventional methods were compared. The results indicated that the highest protein recovery was related to solubility in acid, alkaline and conventional methods, respectively. The highest removal of lipid and myoglobin was observed by solubility in alkali. Excretion of total pigment and sulfhydryl gro...

Background and purpose: Heavy metals are released to the environment as a result of industrial, urban and agricultural sewages. They are usually resistant to chemical dissociation. They can easily contaminate aquatic animals especially fishes which are amongst the food chains of human. This study evaluated the concentration of heavy metals in the tissues of different types of Clupeonella cultri...
Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...
