Shrinking Trout

I was just reading this over at BCLocalNews:

A group of Norwegian and Finnish scientists have recently observed that during cold temperatures, Salmoniods can reduce their body length up to 10%.

The writer, Jeff Weltz, asks himself, “How big, actually, was my friend Dave Rice’s 44-inch, fly-caught Thompson River Steelhead before it shrank?” Well, that could have been almost 49-inches. That’s massive! Then again, 44-inches is massive enough!?
