摘要

这篇文章首次记录了棘颊小龙虾Faxonius limosus的蓝色形态(Rafinesque, 1817)。在波兰的两个不同地点捕获了两只不同颜色的个体，它们彼此相隔约500公里，属于不同的河流集水区(奥德河和维斯瓦河)，在欧洲的物种分布范围内。采用标准DNA条形码技术对所采集的小龙虾进行了分类鉴定。虽然以前在Cambaridae家族中描述过蓝色的小龙虾，但收集到的个体是F. limosus中蓝色的第一次记录。建议用一种新的物种颜色形式补充识别键，这种颜色形式虽然特征暗红色带不清楚，但可能导致识别外来物种，水族馆和本地物种的错误。

First record and DNA barcodes of the invasive blue-coloured spiny-cheek crayfish Faxonius limosus (Rafinesque, 1817) (Decapoda: Cambaridae)

This contribution presents first record of a blue colour morph of spiny-cheek crayfish, Faxonius limosus (Rafinesque, 1817). Two unusually coloured individuals were caught in Poland, in two different locations, separated from each other by approximately 500 km and belonging to different river catchments (Oder and Vistula), within the range of the species occurrence in Europe. Taxonomic identification of collected crayfish has been confirmed by the standard DNA barcoding procedure. Although blue coloured forms of crayfish have been previously described within the Cambaridae family, collected individuals are the first records of blue colouration within F. limosus. It is recommended to supplement identification keys with a new colour form of the species, which, while characteristic dark red bands are not clear, may cause mistakes in recognition of exotic, aquarium as well as native species.

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.
