摘要

刺鲶鱼化石（Bloch，1974）是亚洲一种重要的商业鱼类。本研究描述了H.化石的一些生物学方面，共使用了250个个体，这些个体在2017年7月至2018年6月期间被各种类型的传统渔具捕获，并测量了每个个体的生物特征数据。记录结果显示，TL在10.30至20.50厘米之间变化，BW在4.42至50.91克之间。所有LWR均显著（p 3.00）。LLR显著（p 0.988）。Gajner Beel H.化石的a 3.0、L m和m W分别为0.0063、12.09 cm TL和1.09 y-1。这些发现将对Gajner Beel湿地和邻近生态系统中这种渔业的进一步种群评估和管理非常有效。

Some biological aspects of Asian stinging catfish, Heteropneustes fossilis (Bloch, 1794) (Teleostei: Siluriformes) in a wetland ecosystem

The Stinging catfish, Heteropneustes fossilis (Bloch, 1974) is a commercially important fish species in Asia. This study describes some biological aspects of H. fossilis using a total of 250 individuals which were captured during July 2017 to June 2018 by various types of traditional fishing gears and measured biometric data for each individual The recorded results showed that the TL was varied from 10.30 to 20.50 cm and BW was ranged from 4.42 to 50.91 g. All LWRs were significant ( p 3.00). The LLR was significant ( p 0.988. The a 3.0 , L m , and M W were 0.0063, 12.09 cm TL and 1.09 y -1 for H. fossilis in the Gajner Beel, respectively. These findings would be very effective for further stock assessment and management of this fishery in the Gajner Beel wetland and adjoining ecosystems.

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.
