摘要

本研究旨在研究来自埃及红海的三种锦囊动物Carangoides ferdau、Carangoide malabaricus和Gnathanodon specious在形态计量和分生组织特征上的两性异形。在C.ferdau、C.malabaricus和G.speciosus中，三种锦囊属物种的形态计量指数（相对于SL或HL）的基本统计数据被认为是两性异形，其中一些指数是无大小的，可以作为被检查物种雄性和雌性之间的区分工具。根据双变量概念估计了三个研究物种的雄性和雌性的体型异速测量类型。分生组织特征中未观察到两性异形。应调查其他特征以确定两性异形，以便于出于保护目的和正确管理进行识别。

Sexual dimorphism of morphological characters in three carangid species from the Red Sea, Egypt

The present study was aimed to investigate sexual dimorphism in morphometric and meristic characters of three carangid species Carangoides ferdau , Carangoides malabaricus, and Gnathanodon speciosus from the Red Sea, Egypt. The basic statistics of the morphometric indices (relative to SL or HL) of the three carangid species considered sexual dimorphism in C. ferdau , C. malabaricus, and G. speciosus regarding some indices that are size-free and valid as a discriminating tool between males and females of the examined species. The type of size allometry of males and females of the three studied species was estimated according to the bivariate concept. No sexual dimorphism was observed in the meristics characters. Additional features should be investigated to determine sexual dimorphism to facilitate the identification for conservatory purposes and correct management.

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.
