Illegal fishing with electrofishing devices in the Po river basin, Emilia Romagna, Italy

Abstract Electric fishing is an illegal hunting method, unfortunately widely used by poachers to paralyze fish and to catch many animals in a short time. In Italy, it is authorized only for scientific and conservative purposes. Between 2014 and 2018, the Ferrara section of the Experimental Zooprophy...
