Comparative effectiveness, growth and dispersal of stocked Arctic char (Salvelinus alpinus) from different origins in Lake Annecy
The fisheries managers of the Lake Annecy stocked Arctic char Salvelinus alpinus fingerlings from different origins including progeny of wild brood fish from Lake Geneva, wild brood fish from Lake Annecy and captive brood stock from the INRA hatchery in Thonon to improve the catches. The effectivene...
