Spawning patterns and interspecific matings of sympatric white ( Catostomus commersoni ) and longnose ( C . catostomus ) suckers from the Gouin reservoir system, Quebec
White (Catostomus commersoni) and longnose (C. catostomus) suckers from the Gouin reservoir, Quebec, and a small upstream lake (Lac des Cinq Miles) spawned in the same stream. White suckers numerically dominated the runs in all years; however, abundances of both species decreased eightfold during a...
