  • A summary of paralytic shellfish poisoning in Canada

    White, Alan W.; White, Alan W.; Anraku, Masateru; Hooi, Kok-Kuang (Marine Fisheries Research Department, Southeast Asian Fisheries Development CenterSingapore, 1984)
    Paralytic shellfish poisoning occurs along both the east and west coasts of Canada. Since 1973 there have been more than 300 documented cases of paralytic shellfish poisoning, resulting in about 35 deaths. Causative dinoflagellates include Gonyaulax catenella, G. acatenella and G. excavata. Details are given of shellfish contamination, toxic blooms patterns, toxicity monitoring, impact on shellfish industry and detoxification.
  • Shellfish poisoning in Japanese waters

    Anraku, Masateru; White, Alan W.; Anraku, Masateru; Hooi, Kok-Kuang (Marine Fisheries Research Department, Southeast Asian Fisheries Development CenterSingapore, 1984)
    Under the supervision of the Fisheries Agency, each prefectural government has the responsibility of carrying out monitoring programs. Although some problems exist, monitoring operations have been proceeding successfully. Investigations concerning various aspects of shellfish poisoning are being conducted by 6 national institutions, 15 universities, and about 30 fisheries laboratories. Because shellfish poisoning is a kind of natural phenomenon, the only defense is the establishment of precise monitoring techniques to reduce damages. Efforts to improve monitoring, however, need to be carried out through fundamental research.

    White, Alan W.; Anraku, Masateru; Hooi, Kok Kuang (Marine Fisheries Research Department, Southeast Asian Fisheries Development CenterSingapore, 1984)
    The occurrence of toxic red tides and paralytic shellfish poisoning (PSP) have become more frequent in Southeast Asian waters in recent years. A consultative meeting was organized by the Southeast Asian Fisheries Development Center (SEAFDEC) and the International Development Research Centre (IDRC) of Canada on 11-14 September 1984 to review the status of shellfish toxicity in Southeast Asia and discuss ways and means for its improved study and control. It was attended by 28 officials and researchers from Brunei Darussalam, Canada, Indonesia, Japan, Malaysia, Philippines, Singapore, and Thailand, including participants from the International Center for Living Aquatic Resource Management, IDRC and SEAFDEC. This volume resulted from the meeting and provides, for the first time, a review of past problems and current research on the subject. It includes edited papers, recommendations and conclusions of the meeting. The papers describe the background related to PSP and red tide in the region as well as the measures taken to protect consumers. Also included are resource papers outlining conditions in Canada and Japan and the protective measures which have been adopted by the two countries.
