Sea fish size could shrink by 24%



The Press Association reports:-

Sea fish could be almost a quarter of their current size by 2050 because of global warming, scientists predict.

The scale of the tiddler trend took experts by surprise. They found that even minor changes in ocean temperature and oxygen level led to dramatic shrinkage.

Computer simulations...

Ah - computer simulations eh? Had me worried for a moment. Thought some real science was in the offing, rather than that sitting on your bottom in front of a screen they pass off as science these days. I suppose it makes a journalist's job easier though.

I even thought for a brief and fleeting moment BirdsEye might have to shrink their fish fingers - but no. In any event, I suppose they could just make that bright orange crunchy stuff a bit thicker and use even less fish. So no worries on that score.

Phew!

As someone pointed out @wattsupwiththat, if warmer seas mean smaller fishes how come all the big fishes swim in the tropics and not the North Atlantic?

The report in Nature does point out that the worst effects occur at extremes of their parameter ranges - so the Press takes those extremes - nothing new.

Whether their model is worth anything I don't know but it seems surprising if Mother Nature really is so very fragile.

Suspicions are raised in my mind by the beauty and perfection of the graphics - smells of the computer rather than the research vessel.

Who can afford fish nowadays?

banned - yes, and that's what you would expect, other things being equal.

Roger - I think Mother Nature is neither that fragile nor that predictable.

Angus - pilchards?

Artificial scarcity - what it's all about.

James - yes, there are those who think enough is too much, for us that is.
