Una nuova scala di risalita sarà inaugurata venerdì alla centrale idroelettrica di Isola Serafini, tra Cremona e Piacenza, dopo due anni di lavori. Si tratta dell'ultimo dei cinque impianti realizzati sui fiumi Po, Ticino e Tresa che permettono ai pesci di scorrazzare liberi nel corridoio fluviale di 500 chilometri dall'Adriatico al lago Ceresio.
A beneficiarne più di tutti sarà l’anguilla: l’assenza di ostacoli le permetterà di completare il ciclo di vita, interrotto lungo questo tragitto sin dal 1962, e di tornare nei laghi ticinesi.
Il passaggio permette di riconnettere il reticolo idrografico che si estende per oltre 70'000 chilometri quadrati.
