A group of international fisheries scientists is now pointing out the simple, ecological reality of mathematics long ignored by Alaska salmon managers: addition matters as well as subtraction.
With the human-manipulated ecosystem of the North Pacific Ocean once again oscillating wildly, they are warning that fishery management isn’t just about the removals of salmon via human harvests; it is also about the additions of billions of the little fish now dumped into the ocean each year by industrial-scale salmon hatcheries in Alaska, Japan and Russia.
