Abstract India is endowed with a wide range of ecosystems, of which oceanic island ecosystems viz. Andaman and Nicobar and Lakshadweep are unique and ecologically fragile because of the high degree of endemism in species composition. Altogether 25 species under different faunal groups such as cnidarians, polychaetes, cirripedes, mollusks, and ascidians are reported as invasive species in Indian islands, of which 24 species are found in Andaman and Nicobar Islands, while 4 species are available in Lakshadweep. Ship-mediated invasions, especially ballast water discharge and ship-hull fouling, are the major source of invasions as these islands are located in the vicinity of the international sea route. In the present paper, we have represented these non-native species of fauna and flora to discriminate and identify them as non-native or invasive. This study deals with the diversity and distribution of aquatic invasive species in islands and their detrimental impact on the island ecosystem.

印度岛屿外来水生物种的入侵和潜在风险

摘要 印度拥有广泛的生态系统，其中海洋岛屿生态系统即是。由于物种组成的高度特有性，安达曼、尼科巴和拉克沙威普是独一无二的，生态脆弱。据报道，刺胞动物、多毛类、卷足类、软体动物和海鞘等不同动物群下的 25 种物种是印度岛屿的入侵物种，其中 24 种在安达曼和尼科巴群岛发现，4 种在拉克沙威普发现。船舶介导的入侵，特别是压载水排放和船体污染，是入侵的主要来源，因为这些岛屿位于国际航线附近。在本论文中，我们已经代表了这些非本土动植物物种，以区分它们并将它们识别为非本土或侵入性的。本研究涉及岛屿中水生入侵物种的多样性和分布及其对岛屿生态系统的不利影响。
