La lampreda da ruscello è il pesce dell’anno 2017, degno di protezione. Lo ha stabilito la Federazione svizzera di pesca.
Con questa scelta si è voluto sottolineare l’importanza degli ambienti acquatici naturali o rivitalizzati. Stanno infatti scomparendo molte specie di pesci a causa delle attività umane; fra queste proprio la Lampetra planeri, l’ultima specie di lampreda presente in Svizzera.
Il muso è costituito da un’unica ventosa; il pesce non ha scaglie e la colonna vertebrale è costituita di tessuto connettivo e cartilagine. La pelle è protetta da uno strato abbondante di muco.
