경남 연안 해만 가리비(Argopecten irradians)의 부위별 마비성 패류독소 분포

Abstract

To understand the characteristics of paralytic shellfish poisoning in a major production area of the bay scallop Argo pecten irradians in Korea, the seasonal variation and anatomical distribution of paralytic shellfish toxin (PST) were determined in bay scallops collected from the Gyeongnam coast of Korea from March to May 2018. PST levels in bay scallops in the survey area showed remarkable seasonal variation. PST was first detected at a level of 0.42 mg/kg on April 2, 2018, and the highest toxin level (3.15 mg/kg) was recorded on April 12. Among the tissues of bay scallops, the highest proportion of PST was found in the viscera (54.9%±17.8%), followed by the adductor (22.8%±10.9%), gonads (8.9%±4.6%), gills (7.1%±3.7%), and mantle (6.3%±.8%). In addition, with higher PST levels in the whole tissues of bay scallops, the proportion of PST in the viscera increased, whereas those in the mantle, gill, and gonad tissues decreased. In a high-toxicity group with more than 2.0 mg/kg PST in the whole tissues, the proportion of PST in the viscera was 71.8%±6.7%.
