Abstract

The presence of the exotic species, bitterling, Rhodeus sericeus (Pallas, 1776), is reported for the first time in the freshwater canals of province of Ferrara, Northern Italy. The classification to the species level was supported by the morpho-meristic parameters, in agreement with the range of variability described for the species. The specie was firstly recorded in Italy in the 1990, in the Menago river located in province of Verona, tributary of the Canal Bianco where it was found the following year, and connected to the Po river through the Governolo (MN) and Voltagrimana (RO) navigation canals. In some canals of the province of Modena it was recorded in 1996 and in the lower Secchia River in 1999, while the species was not found in the Panaro River and in the Burana basin whose homonymous canal crosses the province of Ferrara, from west to east. The hydraulic system of artificial canals (4000 km) in the province of Ferrara (2630 Km) is divided in more sub-basins, all related to the Burana-Volano-Navigabile canal that crosses the overall territory from west to east and is used for both irrigation, driving Po River water derived at Stellata (Bondeno. FE) and drainage. The main sub-basins, considered in this study, are the Canale Burana, Po di Volano, Canal Bianco, Canale Navigabile and Canale Circondariale.
