The article does not mention that the sea lamprey is not a native fish and that salmon were existing quite nicely without them, seals and sea lions notwithstanding. Further the article glosses over the fact that the adult sea lamprey is parasitic/predatory (the definition breaks down with them) on the adult salmon, negating the supposed benefit of providing alternate prey for the pinnipeds. There are, however, non-parasitic lampreys that would provide the benefits without the drawbacks.
