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 aim of the present study was to investigate the age structure, length-weight relationship, sex ratio, sexual maturity stages, growth parameters, natural and fishing mortality coefficients of three species of kilka including common, anchovy and bigeye kilka. The fork length–weight relationship of common, anchovy and bigeye kilka were calculated as W=0.000153 FL2.37, W=0.000349 FL2.18 and W...
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.
