摘要

在印度次大陆有一群群(Hilsa)，以Tenualosa toli、T. ilisha和Hilsa kelee三种为代表，对渔民具有重要的经济意义。观察到Tenualosa辛劳在印度次大陆的分布狭窄，以及脆弱性状况。本文描述了印度古吉拉特邦纳尔马达河口采集的托利菌的形态和分生特征。2019年12月，从Bhadbhut渔场的袋网渔获物(10毫米鳕鱼端网目大小)中收集了一个样本。试件尺寸:全长298毫米，标准长度224毫米，重量214克。对其形态计量学和分分性状进行了评价，并与其他已发表的文献进行了比较。根据目前的调查结果，应立即采取措施使该物种在水生生境中恢复活力。

Morphological and meristic features of Vulnerable Tenualosa toli (Valenciennes, 1847) from Narmada estuary, Gujarat, India

A clupeid group (Hilsa) in the Indian sub-continent is represented by three species viz ., Tenualosa toli , T. ilisha and Hilsa kelee , which has great economic significance for the fishers. Tenualosa toil is observed to have narrow distribution in the Indian sub-continent, along with vulnerability status. The present study describes the morphological and meristic features of T. toli collected from the Narmada estuary, Gujarat, India. A single specimen was collected from the bag net catches (10 mm cod-end mesh size) - from Bhadbhut fishing site in December 2019. The size of specimen with a total length of 298 mm, standard length of 224 mm, and weight of 214 g. The morphometric and meristic characters were assessed and compared with other published literature. The present investigation of T. toli suggested that immediate measures should be adopted to rejuvenate the species in the aquatic habitats.

期刊介绍： Started in 1972, this multi-disciplinary journal publishes full papers and short communications. The Indian Journal of Geo-Marine Sciences, issued monthly, is devoted to the publication of communications relating to various facets of research in (i) Marine sciences including marine engineering and marine pollution; (ii) Climate change & (iii) Geosciences i.e. geology, geography and geophysics. IJMS is a multidisciplinary journal in marine sciences and geosciences. Therefore, research and review papers and book reviews of general significance to marine sciences and geosciences which are written clearly and well organized will be given preference.
