Amounts of blood suger contained in living fresh water fish and amphibia has been estimated.
Blood suger of pond cultured fish or gentle stream fish are at a comparatively low concentration, ranging from 15 to 40mg./dl., while that of the fish, living in the rushing stream, has high contents of blood suger, i. e., from 59 to 129mg./dl. The highest value of blood suger content is found with “yamame” trout, Oncorhynchus milktschitsch, to be 129-131mg./dl., while the lowest value of 19mg./dl. in the normal state is assigned to “unagi”, Anguilla japonica, and “namazu”, Parasilurus asotus.
