Maybe I should have said "divest themselves of liquid matter" but that is what I was referring to. Have a look at the bottom of a cooler sometime without anything in it but a freshly caught fish and examine it afterward and there will be slime, water, and a mixture of blood and all of that in there after the fish dies....it weighs at least hundreths of a pound and that is what I meant. After losing by 1/100 of a pound twice I am a firm believer in my statement.
