While that is a terrible thing, it hardly means the end of seafood. Most available salmon aka "atlantic salmon" -- what you get in most restaruants and stores, is farmed. And in warm(er) waters (than wild salmon). And being a warm(er) water fish, it does not get to feed on the very cold water water krill that produces the high levels of long-chained Omega-3 oils (EPA DHA) in wild salmon aka "alaskan" salmon.
And lots of shrimp is farmed. As is most trout. And don't get me started on catfish farms. --- In [email protected], Jason Spock <[EMAIL PROTECTED]> wrote: > > Almost no more seafood after 2048 at current rates, study warns > Nov. 2, 2006 > Special to World Science > > Sea­food will be all but a memory by 2048 if bulging hu­man pop­u­la­tions keep de­vour­ing fish and pol­lut­ing oceans at cur­rent rates, warns a study pub­lished in the Nov. 3 is­sue of the re­search jour­nal Sci­ence. > > There will be few sea­food fish left four decades from now if cur­rent trends keep up, a study sug­gests.
