Sens commun

Method used to evaluate the abundance of fish species in a portion of a stream and to precise the different populations. It consists in the creation of an electric current which attracts fish. Then, paralyzed by electricity, they rise to the surface, which helps their identification and counts. After a little while, fish are free to circulate in the stream again.
