This paper examines the changes in the population biology and biomass of common kilka (Clupeonella cultriventris caspia) in the Iranian waters of the Caspian Sea from 1995-2004. For most years during this 10-year period, we estimated the age structure of the catch, length-weight relationship, von Bertalanffy growth parameters, condition factor, sex ratios, maturity stages determined from ovaria...
تاثیر اسانس زنیان در غلظت های 0 (شاهد)، 5/0، 75/0 و 1% بر رشد و بیان ژنی انتروتوکسین های a و c باکتری staphylococcus aureus در سوریمی ماهی کیلکا (clupeonella cultriventris caspia) در مدت 5، 10، 15 و 20 روز نگه داری در یخچال (4 درجه) بررسی شد. ترکیبات اصلی اسانس شامل تیمول (4/36%)، پاراسایمین (4/31%) و گاما-ترپینن (73/21%) بود. حداقل غلظت بازدارنده رشد و حداکثر غلظت قابل تحمل برای باکتری در محی...

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...
There have been recent changes in the Caspian Sea ecosystem, such as those due to changes in sea level or those caused by the invasive ctenophore, Mnemiopsis leidyi. It is believed that these changes had significant impacts on the absolute and relative abundance of the commercially important anchovy kilka (Clupeonella engrauliformis) and common kilka (C. cultriventris caspia) leading to decline...

تحقیق حاضر با هدف برآورد پارامترهای رشد کیلکای آنچوی (clupeonella engrauliformis svetovidov, 1941) در جنوب دریای خزر انجام گرفت. در این مطالعه که طی سال 1389 انجام شد، نمونه ها هر دو هفته یک بار از بندر صیادی بابلسر جمع آوری شدند. در آزمایشگاه، اندازه گیری و کلاس بندی طولی و وزنی انجام شد. تعیین سن با استفاده از اتولیت ساجیتا صورت گرفت و نتایج با سالهای گذشته مقایسه شد. میانگین طول و وزن کل ماه...
The article considers studying the physiological and biochemical parameters of common sprat (Clupeonella delicatula caspia Svetovidov) taken in western part Middle Caspian Sea at different periods annual cycle. There were studied species pre-spawning state, beginning spawning, feeding stage pre-wintering stage. 
 In fish muscle tissue content water-soluble protein total lipids was determin...
background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...
