Interesting. Tell me a little more about the salt and where you get it. Our Nebraska Game and Parks Commission has a huge fish display at the state fair every fall and I remember one year they got the wrong kind of salt and killed every fish. It might have had iodine in it. I don't remember for sure.
I'm heading to my bluegill reproduction pond right now. I'm going to dewater it and seine all of the reproduction from last year. I will give away the slowest growing 80% to a friend and the rest will go into my second lined pond for feeding. When these fish are sexually mature I will select the top 5%, which represent the top 1% overall and place these back into a reproduction pond. No telling what might happen after three or four more generations. 
I use Morton table salt that I get from the local grocery store. I have been told the iodine could be bad for the fish so I purchase the one that says: This salt doe not contain iodine."
There is an addtive in some farm supply salts that prevents clumpping of the salt called sodium of prussate (sp?). I have been told this can be bad for fish also.
Selection for faster growth? Wish some of the fish farmers were dong that!
