Do habitat measurements in the vicinity of Atlantic salmon ( Salmo salar) parr matter?
Abstract Atlantic salmon, Salmo salar L., parr habitat characterisation is usually performed by in situ measures of key environmental variables taken at the exact fish location if the fishing gear allows precise pinpointing of this location, or in large sampling sections covering a river reach or me...
