摘要

研究了尼日利亚杰巴湖7种淡水鱼类的长重关系和条件因子。共有576人被从湖面上下游用鱼钩、鱼网和刺网捕获。采样涵盖了2017年4月至9月的旱季和雨季。研究物种的生长指数b值在2.23-3.89之间，条件因子在0.47-1.61之间。

Growth pattern and condition factor of seven freshwater fish species from Jebba Lake, north-central Nigeria

Length-weight relationship and condition factor of seven freshwater fish species from Jebba Lake (Nigeria) were investigated. A total of 576 individuals were caught with hook and line, cast and gill nets from up and downstream sections of the lake. Sampling covered dry and raining seasons spanning across April to September 2017. The growth exponent b values of the studied species ranged between 2.23-3.89 and the condition factor between 0.47-1.61.

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.
