Abstract This article examines the non-native fishes in the freshwater bodies of Andaman and Nicobar Islands with a focus on understanding the perception of stakeholders towards providing management solutions. A total of 56 freshwater fish species were reported from Andaman and Nicobar Islands of which 23 species were non-native to the Islands introduced either accidentally or deliberately. Among the 23 fishes introduced, 13 species were found to be transplanted from Indian waters into the Islands and 10 species were non-native to Indian waters. Mosquito Fish (Gambusia affinis), Mozambique Tilapia (Oreochromis mossambicus), Silver Barb (Barbonymus gonionotus), Red Bellied Pacu (Piaractus brachypomus), and Common Carp (Cyprinus carpio) are some of the important invasive species found here. Stakeholder perception studies were undertaken through semi-structured questionnaire and five point likert scale questions. The respondents (N=133) were classified into two groups as a) Fish farmers and b) Research/development personnel. Multinomial logistic regression analysis revealed that the profession of the respondents significantly influenced the awareness about the non-native fishes (p<0.001). Fish farmers (4.04±0.04) and Research/development (4.47±0.21) respondents mutually agreed on the need for awareness and education on the issue of non-native fishes (p<0.01). A management framework is suggested to address the issue of non-native fishes towards effective planning, conservation and management of the fragile Island ecosystems.

利益相关者对印度安达曼和尼科巴群岛非本地淡水鱼类管理的看法和策略

摘要 本文研究了安达曼和尼科巴群岛淡水体中的非本地鱼类,重点是了解利益相关者对提供管理解决方案的看法。据报道,安达曼和尼科巴群岛共有 56 种淡水鱼类,其中 23 种是非本地的,是有意或无意引进的。在引进的 23 种鱼类中,有 13 种是从印度水域移植到岛屿的,10 种不是印度水域的本地物种。蚊鱼 (Gambusia affinis)、莫桑比克罗非鱼 (Oreochromis mossambicus)、银倒钩 (Barbonymus goionotus)、红腹鲮 (Piaractus brachypomus) 和鲤鱼 (Cyprinus carpio) 是这里发现的一些重要入侵物种。通过半结构化问卷和五点李克特量表问题进行利益相关者感知研究。受访者(N=133)分为两组:a)养鱼者和b)研究/开发人员。多项逻辑回归分析显示,受访者的职业显着影响了对非本地鱼类的认识(p<0.001)。养鱼户 (4.04±0.04) 和研究/开发 (4.47±0.21) 受访者一致同意需要对非本地鱼类问题进行认识和教育 (p<0.01)。建议建立一个管理框架来解决非本地鱼类问题,以有效规划、保护和管理脆弱的岛屿生态系统。受访者(N=133)分为两组:a)养鱼者和b)研究/开发人员。多项逻辑回归分析显示,受访者的职业显着影响了对非本地鱼类的认识(p<0.001)。养鱼户 (4.04±0.04) 和研究/开发 (4.47±0.21) 受访者一致同意需要对非本地鱼类问题进行认识和教育 (p<0.01)。建议建立一个管理框架来解决非本地鱼类问题,以有效规划、保护和管理脆弱的岛屿生态系统。受访者(N=133)分为两组:a)养鱼者和b)研究/开发人员。多项逻辑回归分析显示,受访者的职业显着影响了对非本地鱼类的认识(p<0.001)。养鱼户 (4.04±0.04) 和研究/开发 (4.47±0.21) 受访者一致同意需要对非本地鱼类问题进行认识和教育 (p<0.01)。建议建立一个管理框架来解决非本地鱼类问题,以有效规划、保护和管理脆弱的岛屿生态系统。多项逻辑回归分析显示,受访者的职业显着影响了对非本地鱼类的认识(p<0.001)。养鱼户 (4.04±0.04) 和研究/开发 (4.47±0.21) 受访者一致同意需要对非本地鱼类问题进行认识和教育 (p<0.01)。建议建立一个管理框架来解决非本地鱼类问题,以有效规划、保护和管理脆弱的岛屿生态系统。多项逻辑回归分析显示,受访者的职业显着影响了对非本地鱼类的认识(p<0.001)。养鱼户 (4.04±0.04) 和研究/开发 (4.47±0.21) 受访者一致同意需要对非本地鱼类问题进行认识和教育 (p<0.01)。建议建立一个管理框架来解决非本地鱼类问题,以有效规划、保护和管理脆弱的岛屿生态系统。
