Abstract

The larvae of crustaceans, including those of brachyuran crabs, are a significant part of zooplanktonic communities constituting an ecologically important fraction of the pelagic communities. The present study describes taxonomic studies on three megalop stages of Portunus pelagicus (Linnaeus, 1758), Charybdis feriatus (Linnaeus, 1758) and Carcinus maenas (Linnaeus, 1758) belonging to family Portunidae collected from Indus deltaic creek system. Zooplankton samples were collected from three locations: Shahbandar 24°15’48.083’N, 67°90’15’333’E, Ketibandar 24°9’16.06’N, 67°27’7.64’E and Korangi creek 24°48’18.80’’N, 67°12’30.31’E during April to October 2018. No data available on taxonomic studies of portunid megalops upto species level from Paksitan, hence this is a first attempt to examine and to describe taxonomic features of megalops collected in the zooplankton samples. This study will contribute to the scientific knowledge on megalops taxonomy and identification as well as be useful for future research by taxonomists and biologists.

印度河三角洲(北阿拉伯海)3种梭子鱼(十足目，2腕足目，梭子鱼科)巨蛋期的形态描述

甲壳类动物的幼虫，包括短尾蟹的幼虫，是浮游动物群落的重要组成部分，在生态学上是上层生物群落的重要组成部分。本文报道了从印度三角洲溪系采集的Portunus pelagicus (Linnaeus, 1758)、Charybdis feriatus (Linnaeus, 1758)和Carcinus maenas (Linnaeus, 1758)属Portunidae科的3个巨型期的分类研究。2018年4 - 10月在沙班达尔24°15′48.083′N、67°90′15′333′e、克提班达尔24°9′16.06′N、67°27′7.64′e和科兰吉溪24°48′18.80′N、67°12′30.31′e三个地点采集浮游动物样本。由于目前在巴基斯坦尚无关于巨型浮游动物样本中巨型浮游动物的分类研究数据，因此本文是首次对浮游动物样本中收集的巨型浮游动物的分类特征进行研究和描述。本研究将为今后的分类学家和生物学家的研究提供科学依据。
