Abstract

The freshwater Prussian carp, Carassius gibelio (Bloch, 1782) is a cyprinid, known as a hazardous species for native fish communities. In the present study, some population parameters, including length-weight relationship ( LWR ), condition factor ( KF ), relation condition factor ( K n ), age and growth of C. gibelio in the Azad dam, Kordestan Province, Iran were estimated. The LWR indicating a positive allometric growth pattern. The von Bertalanffy growth parameters were estimated as L ∞ =337mm, K =0.255 yr -1 , t 0 =-0.21 yr. There was a significantly positive correlation between TL and KF ( r 2 =0.89). The average of K n was lower than 1 which suggested that the well-being of the fish was not good in the Azad dam region.

伊朗西部Azad坝湖gibelio Carassius (Bloch, 1782) (Teleostei:鲤科)的一些生物学特性

淡水普鲁士鲤鱼Carassius gibelio（Bloch，1782）是一种鲤鱼，被认为是当地鱼类群落的危险物种。本研究估计了伊朗科尔德斯坦省阿扎德大坝吉贝利奥的一些种群参数，包括长重关系（LWR）、条件因子（KF）、关系条件因子（Kn）、年龄和生长情况。LWR表明正的异速生长模式。von Bertalanffy的生长参数估计为L∞=337mm，K=0.255 yr-1，t0=-0.21 yr。TL与KF之间存在显著的正相关（r2=0.89）。Kn的平均值低于1，这表明阿扎德坝区鱼类的健康状况不佳。

期刊介绍： Iranian Journal of Ichthyology (IJI) is a peer-reviewed journal for publication of high quality papers on any aspect of ichthyology and will be published 4 times a year by the Iranian Society of Ichthyology (http://www.isi-org.ir). The journal welcomes the submission of manuscripts that meets the general criteria of significance and scientific excellence, and will publish original scientific articles in the fields of ichthyology. The editors welcome the submission of original manuscripts including Research Articles, Short communications, and Views & News. Review papers by distinguished authors and Special Issues will also be considered. It is our aim to provide the international scientific community with an efficiently published journal, meeting high scientific and technical standards. Scopes of Iranian Journal of Ichthyology includes: Systematics, taxonomy, morphology, anatomy, biogeography, biodiversity, conservation, ecology and general biology of fishes (reproduction, food and feeding habits, age and growth, population dynamics, etc.). Papers on freshwater, brackish, marine and fossil fishes will be considered.
