[ 2 ] - Age and growth of bigeye kilka (Clupeonella grimmi Kessler, 1877) in Iranian waters of the Caspian Sea
Age and growth of Bigeye Kilka, Clupeonella grimmi, were studied in Iranian waters of the Caspian Sea from early May 2006 to April 2007. The sagitta otoliths were removed for each 5 mm length interval up to a total number of 262 fish. Fork length and weight ranged from 92.5 to 142.5 mm and 4.2 g to 23.4 g, respectively. The largest length-groups was observed from December to February and the lo...
[ 3 ] - Fishery and biological aspects of anchovy Kilka ( Clupeonella engrauliformis) in the southern Caspian Sea
This paper aimed to investigate the fishery and biological characteristics of anchovy Kilka in Iranian waters of the Caspian Sea from 2005-2007, including length and age structure ,Von Bertalanffy growth parameters, length and age at first capture, condition factor, sex ratio, natural and fishing mortality. The examination of catch data approved that Kilka population in the Caspian Sea have b...
[ 4 ] - Significant changes in pelagic fish stocks of Clupeonella spp. in the south Caspian Sea
The present study was carried out during 2006-2007 along the southern Caspian Sea. The species composition showed that the common kilka, Clupeonella cultriventris caspia, is dominant species with 89% and then anchovy, C. engrauliformis, has shown only 8.7% while it was already dominant species in the past decades. The overall results indicated that common kilka was replaced with anchovy kilka ...
[ 5 ] - Reproduction characteristics of the Vimba vimba persa
Some reproduction characteristics of the Caspian Vimba, Vimba vimba persa, were studied from Oct. 2008 to Sep. 2009 in coastal waters of the Caspian Sea (Mazandaran province). 994 specimens were monthly collected from 6 fish landing sites of Ramsar, Tonekabon, Chalus, Mahmood Abad, Sari and Behshahr. The fecundity was measured using 92 specimens. This species was found to have more abundance in...
[ 6 ] - Reproduction and spawning patterns of the Scomberomorus commerson in the Iranian coastal waters of the Persian Gulf & Oman Sea
Reproduction and spawning patterns of the king fish (Scomberomorus commerson) were studied in the Persian Gulf (Hormozgan Province) and Oman Sea from Oct 2006 to Sep 2007. A total of 1120 fish was collected from different landing sites along the Iranian waters. Yearly analysis of the reproductive stages and gonadosomatic index showed a single reproductive cycle beginning in March and continue...
[ 7 ] - Validation of back-calculation methods using otoliths to determine the length of anchovy kilka (Clupeonella engrauliformis)
Age structure of the Caspian Sea anchovy kilka, Clupeonella engrauliformis, was estimated for the first time by back-calculation methods. Otolith growth and the rate of increment in anchovy kilka were examined to determine whether otoliths could be used to back calculate body sizes at various life stages. Sampling was carried out on commercial fishing vessels board along the Iranian coast in 20...
[ 8 ] - Estimation of growth parameters and mortality rate of common carp (Cyprinus carpio, Linnaeus 1758) population in the southern Caspian Sea
Common carp (Cyprinus carpio) represents one of the most economically important fish species in the Caspian Sea. In this study, growth and mortality parameters among population of common carp was investigated. Sampling was carried out weekly, using beach seine in the south of the Caspian Sea from October 2006 to September 2007. As a contribution to elaborating management programs for common car...

A total of 1120 fish was collected from different landing sites along the Iranian waters. Yearly analysis of the reproductive stages and gonadosomatic index showed a single reproductive cycle beginning in March and continue...
[ 10 ] - تخمین پارامترهای رشد و ضرایب مرگ و میر ماهی شانک زردباله Acanthopagrus latus در آبهای غرب استان هرمزگان
در این تحقیق پویایی جمعیت ماهی شانک زرد باله شامل پارامترهای رشد و ضرایب مرگ و میر، رابطه طول- وزن و همچنین وضعیت فعلی بهره‌برداری این گونه در منطقه غرب استان هرمزگان مورد بررسی قرار گرفت. نمونه‌برداری از سه مرکز تخلیه‌ی بندر عباس، بندر لنگه و قشم به‌صورت ماهانه طی دوره یک ساله از مرداد 89 لغایت تیر 90، از صید تجاری تخلیه شده به ایستگاه‌های فوق و به‌صورت تصادفی انجام شد. رابطه‌ی طول چنگالی و وز...
