Description:
The phenomenon of the downstream movement of brown trout fry has been noticed for a very long time by fish biologists. The work presented here, and taking place in the framework of the hydrobiological research of the INRA, represents the results of three years' observation of the movement downstream in the Lissuraga, a small stream in the French Basque country, in connection with certain environmental factors, which are shown. The authors have used a live experiment to compare, in an artificial stream, the ”descending” (or ”Nomadic”) fry with the ”resident” fry, caught by electric fishing in other parts of the stream.
