Abstract

Sailfin catfish indigenous to South America are very popular ornamental fish, having previously been introduced to many regions outside their native range. Two species, namely Pterygoplichthys disjunctivus and P. pardalis, are illegal but widespread in Indonesia. They have formed self-sustaining populations, exploited for feeding of domestic animals and locally for human consumption. Also possible hybrids of the two mentioned species were recorded. The surveyed populations were considered established which perfectly fits with the climate matching analysis. Further monitoring and inspection of regions highlighted to be suitable for sailfin catfish is recommended.

产于印度尼西亚的两种非法南美帆鳍鲶鱼，属翼鱼属

帆鳍鲶鱼原产于南美洲，是非常受欢迎的观赏鱼，以前曾被引入到许多地区以外的地方。两种，即Pterygoplichthys disjunctivus和P. pardalis，是非法的，但在印度尼西亚广泛分布。它们已经形成了自给自足的种群，被用来喂养家畜，并在当地供人类消费。还记录了这两种植物可能的杂交。被调查的人口被认为是确定的，这完全符合气候匹配分析。建议进一步监测和检查被强调适合长鳍鲶鱼的地区。

期刊介绍： Knowledge and Management of Aquatic Ecosystems (KMAE-Bulletin Français de la Pêche et de la Pisciculture since 1928) serves as a foundation for scientific advice across the broad spectrum of management and conservation issues related to freshwater ecosystems. The journal publishes articles, short communications, reviews, comments and replies that contribute to a scientific understanding of freshwater ecosystems and the impact of human activities upon these systems. Its scope includes economic, social, and public administration studies, in so far as they are directly concerned with the management of freshwater ecosystems (e.g. European Water Framework Directive, USA Clean Water Act, Canadian Water Quality Guidelines, …) and prove of general interest to freshwater specialists. Papers on insular freshwater ecosystems and on transitional waters are welcome. KMAE is not a preferred journal for taxonomical, physiological, biological, toxicological studies, unless a clear link to ecological aspects can be established. Articles with a very descriptive content can be accepted if they are part of a broader ecological context.
