| Abstract: |
| Recent researches in relation to Paralytic Shellfish Poisoning (PSP) undertaken in the 1980s and 1990s are discussed. The most important advances are listed below. l) Immunological and genetic probes have been used in the identification of toxic algae, which could simplify the process of algae examination and enumeration. These techniques could be further used in field investigations of toxic algal blooms. 2) Bacteria are found to be able to produce PSP. Several strains of toxic bacteria have been isolated and cultured successfully in the laboratory. However, other studies indicated that PSP toxin production is generally related to the toxin algae. Such, the mechanism of toxin production in dinoflagellate remains unclear. 3) New biological and chemical methods have been developed in monitoring and analyzing PSP, such as immunoassays, neuroreceptor binding assays, cytotoxicity bioassays, high performance liquid chromatography (HPLC) and capillary electrophoresis (CE). 4) Studies in an attempt to elucidate toxicological and ecotoxicological effects of PSP have been undertaken. Toxin accumulation and transformation are confirmed in marine organisms of low trophic level, especially in shellfish. 5) Impacts of PSP on mariculture and according management are summarized. Research work on PSP in China started from the beginning of the 1990s. Several research fields with priority are proposed according to the present research status in China. |
