A total of 15 specimens (8 males, 7 females) of the pufferfish Fugu stictonotus (“gomafugu”) were collected from Kuji, Miyako, and Funakoshi Bays, Iwate Prefecture, and examined for anatomical distribution of toxicity by the standard assay method using mice.The frequency of toxic specimens was 87% for skin, 86% for ovary, 43% for bile, 33% for liver, and 27% for digestive canal contents. One out of the 15 specimens possessed toxic muscle.The highest toxicity scores recorded were 3, 300MU/g liver, 2, 700MU/g ovary, 1, 000MU/g digestive canal contents, 660MU/g skin, etc.This, along with the finding that the northern Kyushu specimens were endowed with nontoxic to weakly toxic livers and ovaries, suggests a wide local variation in the toxicity of F. stictonotus.
