One Species With Two Biologies: Atlantic Salmon (Salmo Salar

Abstract: Today, over 94 % of all adult Atlantic salmon (Salmo salar) are in the aquaculture niche and wild numbers continue to decline while aquaculture numbers increase. The developmental and evolutionary forces in the aquaculture or “domestic ” niche are so unlike those in the wild niche that two...

A polarization of views between aquaculturists and environmentalists will not resolve the problems. The three interest groups in fisheries — aquaculture, biodiversity, and capture — must begin to work together if we are to take up the challenge of preserving biodiversity and if aquaculturists, who hold the future of Atlantic salmon in their hands, can be expected to willingly prevent further impacts from their industry.
