Abstract

The authors carried out paralytic shellfish poison bioassay on the 9 kinds of shellfishes collected from Pusan and Kyungnam areas of Korea from April to July, 1986. The areas are the main producing district of fisheries in Korea and the samples were collected from their producing sites-natural, cultured and marketed. There were little or no PSP in the majority of the shellfishes, but 3 natural (Pusan Il-Kwang <TEX>$700{\mu}g$</TEX>, Koje Okpo <TEX>$648{\mu}g$</TEX>, Chungmoo Madong <TEX>$124{\mu}g/100gm$</TEX> meat) and 1 marketed (Pusan Chakalchi <TEX>$490{\mu}g/100gm$</TEX> meat) blue mussels contained relatively high PSP only in April. It is considered that there will be a possibility of paralytic shellfish poisoning, and control program for preventing the poisoning is necessary in Korea.
