Abstract Ornamental fish culture and aquarium keeping have become a booming sector worldwide. It has been observed that a number of stakeholders are involved in introducing exotic ornamentals in India as well, as the takers are interested on variants and new species. Most of the exotic ornamental fishes are also being domesticated in India, since the demand is readily fulfilled through adequate supply to the hobbyists. This sector provides livelihood option to many people and helps to earn millions of dollars to our country every year, however, the invasion of exotic ornamentals in our natural water bodies needs to be assessed, monitored and controlled with due attention as it is a staid menace to our biodiversity. Around 400 species / variants of exotic freshwater ornamentals and around 100 exotic marine ornamental species including invertebrates are found to have introduced in the trade. It is significant to note that an apparent violation in the trade is taking place by concealing the Government of India approval, which is given only for 92 species / variants of fishes for import. Further, as some of the freshwater ornamental fishes currently available in the aquarium trade have invaded through natural water bodies, their impacts need to be studied in detail. To deal with the situation, the proper precautionary approach should be implemented by adopting measures after having proper quarantine, meticulous risk analysis and strategic prevention methods as well. Combined efforts of industry stakeholders with different government agencies, academic and research institutions is required and a suitable protocol has to be formulated for permissible import, sustainable production, supply and management.

管理外来观赏鱼引进的管理策略，印度淡水生态系统的无声入侵者

摘要 观赏鱼养殖和水族饲养已成为世界范围内蓬勃发展的行业。据观察，许多利益相关者也参与了在印度引进外来观赏植物的工作，因为接受者对变种和新物种感兴趣。大多数外来观赏鱼也在印度被驯化，因为通过向爱好者提供充足的供应很容易满足需求。这个部门为许多人提供了生计选择，并帮助我们每年为国家赚取数百万美元，然而，我们的天然水体中的外来观赏植物的入侵需要得到适当的评估、监测和控制，因为它是一个稳定的威胁对我们的生物多样性。约 400 种外来淡水观赏植物 / 变种和约 100 种外来海洋观赏物种，包括无脊椎动物被引入贸易。值得注意的是，通过隐瞒印度政府的批准，显然存在贸易违规行为，该批准仅适用于 92 种/变种鱼类的进口。此外，由于目前水族贸易中的一些淡水观赏鱼已经通过天然水体侵入，因此需要详细研究它们的影响。应对这种情况，应采取适当的预防措施，在采取适当的隔离措施、细致的风险分析和战略预防措施后采取措施。行业利益相关者与不同政府机构的共同努力，
