All’inizio del secolo scorso nel Reno vivevano centinaia di migliaia di salmoni. A partire dagli anni trenta, a causa dell’inquinamento, il loro numero è costantemente diminuito fino a scomparire completamente. Entro il 2020 dovrebbe essere possibile rivedere il pesce risalire la corrente dal mare del nord fino a Basilea grazie agli sforzi congiunti della Svizzera e degli altri paesi rivieraschi. E proprio li si concentrano gli sforzi del programma salmone 2020 della Svizzera e degli stati che si affacciano sul Reno. Brigitte Schwarz è arrivata in Alsazia dove, nella riserva naturale Petite Camargue Alsacienne (Piccola Camargue Alsaziana), nell’antica piscicultura imperiale, ha incontrato il biologo Olivier Sommen responsabile dell’allevamento di avannotti di salmone destinati a ripopolare il Reno.
