Abstract: Three species of bivalves (mussel Mytilus edulis, hard clam Meretrix lamarckki, surf clam Pseudocardium sachalinensis ) collected in Ibaraki Prefecture, Japan , have been investigated on the toxicity of paralytic shellfish poison (PSP) from 1990 to 1996. PSP highly exceeding the Japanese regulatory limit (4MU/ g edible part) was detected in mussel in April, 1991 and 1993. In 1994,1995 and 1996 PSP over the criterion was detected not only in mussel but also in hard clam or in surf clam , successively. Toxicity of each bivalve appeared through late in March to early in April, showed the highest score in April and disappeared middle in May in common with each year. The velocity of rise and fall of toxicity, however, was different dependent on the species of bivalves.  Anatomical parts of toxificated hard clam and surf clam were also examined on the toxicity. Digestive glands showed the highest score in all the cases, and the other parts also showed lower toxicity except for hard clam.
