Abstract

The toxicity of two species of puffer fish, Takifugu poecilonotus (Heuinjeombok) and T. vermicularis (Gukmaeribok) collected from the coastal regions of Korea was determined using a mouse bioassay. In the T. poecilonotus collected in Jeju and Tongyeong, the proportion of toxic specimens containing ${\ge}10$ mouse units (MU) per gram exceeded 95% for the skin, liver, ovary, and fin, and approximately 30% for the testis and muscles. In each of the organs, the highest toxin levels were 79 MU/g in the muscle, hundreds (158-365) of MU per gram in the fin, intestine, testis, and gallbladder, but thousands (1,147-2,406) of MU per gram in the skin, liver, and ovary. In T. vermicularis collected from Incheon and Gunsan, the proportions of toxic specimens were 100% for the gallbladder, and 56-68% for the skin, fin, liver, and intestine however, no toxic muscle specimens were noted. The highest toxin scores were below 10 mouse units (MU) per gram in the muscle, 20-94 MU/g in the skin and fin, 319 MU/g in the intestine, and thousands (1,548-4,624) of MU per gram in the liver, gonad, and gallbladder. The toxicity in the muscle of T. vermicularis was deemed acceptable for human consumption, whereas the toxicities in the muscle of T. poecilonotus and the skin of both species of puffer fish were significantly high, such that special attention may be required when the fish is intended for human consumption.
