Structural and compositional mismatch between captive and wild Atlantic salmon ( Salmo salar) parrs’ gut microbiota highlights the relevance of integrating molecular ecology for management and conservation methods
Abstract Stocking methods are used in the Province of Quebec to restore Salmo salar populations. However, Atlantic salmon stocked juveniles show higher mortality rates than wild ones when introduced into nature. Hatchery environment, which greatly differs from the natural environment, is identified...
