The present study aimed to analyse the influence of physico-chemical properties on zooplankton assemblages and species diversity in a lagoon system. The study was carried out in coral reef lagoon of Kavaratti Island, Lakshadweep Archipelago, India during the monsoon of the year 2017. Zooplankton assemblages, distributed among 56 taxonomic units, were found to be dominated by copepods (63.27%, 34 taxa) followed by cladocerans (11.14%, 7 taxa), ostracods (9.87%, 2 taxa), ciliates (6.23%, 6 taxa), chaetognaths (4.32%, 3 taxa), leptomedusae, (1.25%, 1 taxa), and appendicularians (3.92%, 3 taxa). Copepods assemblages showed maximum density of 14326 ind m⁻³ from S1, in which leptomedusea was the lowest abundant taxa (284 ind m⁻³). Shannon–Wiener-index between 3.725–3.860 attested to the fact that the species diversity and richness predominated in lagoon than that in offshore. Canonical Correspondence Analysis revealed the environmental parameters influencing the abundance and occurrence zooplankton community in the study area.

本研究旨在分析理化性质对泻湖系统中浮游动物组合和物种多样性的影响。该研究是在2017年的季风期间在印度拉克沙迪普群岛的卡瓦拉蒂岛的珊瑚礁泻湖中进行的。发现浮游动物组合分布在56个生物分类单元中，以co足类动物为主（63.27％，34个分类单元），其次是锁骨（11.14％，7个分类单元），rac类（9.87％，2个分类单元），纤毛虫（6.23％，6个分类单元），e鱼（4.32％，3个分类单元），钩毛纲（1.25％，1个分类单元），和附属动物（3.92 ％，3个分类单元）。pe足类组合显示出S1的最大密度为14326 ind m ^-3，其中瘦足鱼类是最低的丰富类群（284 ind m ^-3）。Shannon–Wiener指数介于3.725–3.860之间，这证明了泻湖的物种多样性和丰富度高于近海的物种多样性和丰富度。典范对应分析揭示了影响研究区域浮游动物种群数量和发生的环境参数。
