Warmer seas 'are making fish smaller' http://apocadocs.com/s.pl?1390953193
A decline in the size of some species of fish in the North Sea could be due to a rise in water temperatures, according to research.
Scientists found that the maximum length of haddock, whiting, herring, Norway pout, plaice and sole decreased by as much as 29 percent over a 38-year period when temperatures in the North Sea increased by between 1C and 2C.
The availability of food and an increase in fishing could also be factors in the reduction in length but the "synchronised" fall in size across a range of species led the fisheries scientists at the University of Aberdeen to identify climate change, and particularly higher water temperatures, as a common theme....
Dr Baudron added: "The increase in temperature of the North Sea is actually quite subtle - approximately 2C - yet this appears to be having a detectable impact on growth rates of fish.

I know we need something to replace the vanishing phytoplankton, but isn't this the wrong way to go about it?
