Abstract India, a megadiverse tropical country is grappling with the rising trend of aquatic invasions. Out of 532 introduced non-native fish, 16 species of freshwater aquaculture and aquarium were assessed invasive by using a risk assessment protocol, ‘Fish Invasiveness Screening Test’. Six major identified invasion pathways of the aquatic invasive species were inadvertent or deliberate releases, escapes, contaminants from hatcheries, river corridors, stowaways and unaided introductions. Invasion mechanism further elucidated the factors promoting successful invasion in freshwater ecosystems. For predictive future performance of invasive fish, the concrete and predictive values based on mean abundance by weight was calculated. Over 28.67% and 29.02 % persistent increased yield of the invasive Tilapia and Common Carp respectively was predicted in the Ganga river in the coming decades. Single species Tilapia invasion facilitated multiple species fish invasion, manifesting in invasion meltdown. The trophic changes due to fish invasion exhibited biotic homogenization with trophic downgrading. Aquatic invasive species were found highly competitive interacting with native species causing serious biodiversity loss, health hazards, and economic damage consequently affecting the ecosystem services. In spite of available regulatory approaches and guidelines to manage aquatic invasive species, fish invasion has been on the rise. This paper suggests modifications and stringent implementation of the existing regulatory mechanisms besides adopting linkages, cutting-edge research on invasion science and modern molecular containment tools for effective management.

印度热带水生入侵物种状况：概述

摘要 印度是一个生物多样性丰富的热带国家，正在努力应对水生入侵的上升趋势。在 532 种引进的非本地鱼类中，16 种淡水养殖和水族馆通过使用风险评估协议“鱼类入侵性筛查测试”进行了入侵性评估。已确定的水生入侵物种的六种主要入侵途径是无意或故意释放、逃逸、孵化场污染物、河流走廊、偷渡者和自行引入。入侵机制进一步阐明了促进淡水生态系统成功入侵的因素。为了预测入侵鱼类的未来表现，计算了基于重量平均丰度的具体和预测值。超过 28.67% 和 29。预计未来几十年恒河的入侵罗非鱼和鲤鱼产量将分别持续增加 02%。单种罗非鱼入侵促进了多种鱼类入侵，表现为入侵崩溃。鱼类入侵引起的营养变化表现为生物同质化和营养降级。发现水生入侵物种与本地物种具有高度竞争性的相互作用，导致严重的生物多样性丧失、健康危害和经济损失，从而影响生态系统服务。尽管有管理水生入侵物种的可用监管方法和指南，但鱼类入侵一直在上升。本文建议修改和严格执行现有的监管机制，除了采用联系方式，
