A total number of samples, 300 fish were randomly caught by conical nets in the study areas and analyzed. Overall, the average total length of the three stations 11.65 ± 1.17 cm and 9.64 ± 2.58 g total ...
تحقیق حاضر با هدف مطالعه رشد و وضعیت تولیدمثل کیلکای معمولی clupeonella caspia در سال 1389 در سواحل مازندران انجام شد. در مجموع 3774 نمونه بعد از اندازه گیری طول و وزن، کالبدشکافی و تعیین جنسیت شده و گناد ماده ها توزین شد. تعیین مرحله رسیدگی جنسی بر اساس روش 6 مرحله ای صورت گرفت. تعیین سن با استفاده از اتولیت ساجیتا انجام شد. رابطه طول و وزن به صورت (r2=0.918) بود. پارامترهای رشد این گونه (l?=1...
The effect of salting by different salt composition on fatty acid profile studied in hot smoked Black and Caspian Sea sprat, Clupeonella cultriventris. After initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % NaCl (treatment 1 or T1) and 75 % NaCl- 25 % KCl (treatment 2 or T2) under 15% brine solution for 3 hrs. The smoking proc...
Fish Protein Concentrate (FPC) is a healthy, sustainable and high nutritive product that produced from fish and protein and other nutrients are more concentrated than in the fresh fish. The aim of this research is to study the sustainability of FPC produced from Kilka (combination of three Caspian Sea Kilka species, Clupeonella engrauliformis, C. grimmi and C. cultriventris which were not ident...
This study was conducted to investigate morphometric variation and differentiation in common kilka (Clupeonella cultriventris) caught from Amir Abad and Babolsar fishing ports during winter 2013. Totally, 330 specimens (272 specimens from Amir Abad port and 58 specimens from Babolsar port) were caught by lift net and 30 absolute morphometric traits, 9 meristic traits, length and gonad, body wei...

the present research aimed to study the growth and reproductive parameters of common kilka clupeonella caspia in southern caspian sea in 2010. after measuring the length and weight of 3774 samples, they were dissected, sex determined and female gonads were weighed. sexual maturity classification was carried out based on six stages. age was determined using sagitta otoliths. length-weight relati...
سوق داده شدن قسمتی از انرژی دریافتی به سوی تولید مثل همچنین، کمبود منابع غذایی در ماههای انتهایی دورة تولید مثل ممکن است باعث کندشدن روند رشد سایر اندامها در ماهی کیلکا شود. هدف اصلی این تحقیق بررسی خصوصیات زیستی کیلکای معمولی و روند رشد ارگانهای آن در ماههای منتهی به تخم ریزی است. نمونه گیری به تعداد 300-350 قطعه کیلکا در منطقة صید تجاری بابلسر (ساری تا محمودآباد)، از مهر 1387 تا فروردین 1...
در این پژوهش نخست میزان فعالیت آنتی اکسیدانی روغن هسته ی انار و روغن هسته ی انگور بر روغن ماهی کیلکای معمولی (clupeonella cultriventris) برای انتخاب بهترین غلظت ارزیابی شد. از مدل d-optimal mixture design برای طراحی تیمارها استفاده شد. اثر روغن هسته ی انار و روغن هسته ی انگور در غلظت های 0/0، 07/0، 15/0، 22/0و 3/0 درصد در به تأخیر انداختن فرآیند اکسایش در روغن ماهی خام تعیین شد. با اندازه گیری ...
