摘要
绿太阳鱼原产于美洲,主要分布于北美中部。该鱼于1999年作为观赏和游钓用鱼引入我国,主要在广东、广西等地养殖,野外种群已扩散至安徽、四川等地,但在贵州尚无分布记录。2020年7月至2021年10月,在贵州省6个调查点采集到11尾成体标本。调查结果显示,6个调查点均无绿太阳鱼的养殖,推测绿太阳鱼的入侵可能是其他经济鱼类养殖时所引入或放生所致,该鱼在贵州是否形成可繁殖的种群尚需进一步调查和研究。
Lepomis cyanellus Rafinesque, 1819 is native to the Americas, and mainly distributes in the central area of North America.This fish was introduced into China in 1999 as an ornamental fish and game fish.Lepomis cyanellus is mainly farmed in Guangdong and Guangxi;its wild population has spread to Anhui and Sichuan, but there’s no distribution record in Guizhou.Eleven individuals of Lepomis cyanellus were collected from six sampling sites in Guizhou from July 2020 to October 2021.Further investigation showed that the six sampling sites had no farming industry of Lepomis cyanellus.We speculate that the Lepomis cyanellus came from the farming of other economic fishes or the releasing of ornamental fishes.Whether this fish would form viable breeding populations in Guizhou needs further investigation.
