Abstract

This study describes the invasion of the upper Paraná River basin by Pterygoplichthys ambrosettii based on a literature review and field samples. Pterygoplichthys ambrosettii has been reported in 42 localities throughout the upper Paraná River basin, including the Tietê, Paranapanema, Paraná, Grande and Aguapeí rivers. The ascent of P. ambrosettii after the inundation of the Sete Quedas Falls on the Paraná River and the release of individuals by aquarium hobbyists were the primary drivers of this invasion.

摘要

本研究基于文献综述和实地采样，描述了安氏翼甲鲶对巴拉那河上游流域的入侵情况。在巴拉那河上游流域的42个地点都有安氏翼甲鲶的记录，包括蒂埃特河、巴拉那帕内马河、巴拉那河、格兰德河和阿瓜佩伊河。巴拉那河上塞特克达斯瀑布被淹没后安氏翼甲鲶的溯河洄游以及水族爱好者放生个体是此次入侵的主要驱动因素。
