Description A 15 year data set revealed that the abundance of 0+ year Rhodeus amarus in a regulated river was negatively associated with mean river discharge, while mean standard length was positively related to the cumulative number of degree-days above 10C. Results are discussed in the context of the recent invasion success of R. amarus.
