At the Barsebek plant, where I worked for 10 years, we for many years 
had a "fish growing plant" (I don�t know the correct English word but 
believe that you understand what I mean) where the cooling water 
taken from the sea after cooling the steam from the reactor in the 
condensor (thus getting 10 degrees C warmer than the sea) was lead 
directly from the condensor to the "fish growing plant" where some 50 
tons of salmon a year were "produced". Since the water was warmer 
than the sea they kept eating through the winter and grew quicker 
than normal. So about one year was gained. There also were some other 
intersting kinds of flat fish, crayfish and asian giant shrimps.
That plant was run as a joint business and research project.
This project was stopped because it wasn�t easy to sell "nuclear 
salmon" to the public.

So this does not support what you say about salmon not standing warm 
water. Maybe there are different kinds of salmon?
