| In this manual a review is provided of the chemical and toxicological aspects of Amnesic Shellfish Poisoning (ASP). The document contains information on chemical structure, chemical data, where to obtain standards and reference materials, the origin and occurrence, chemical analysis, mouse bioassay, epidemiology, mechanisms of action, symptoms and therapeutics. The practical use of this document has been highlighted in agreement with the Members of the Task Team on Aquatic Biotoxins. This document is prepared by Dr. H. Ravn, IOC together with Prof. T. Yasumoto, Tohoku University, Japan, Chairman of the Task Team on Aquatic Biotoxins. Dr. J. Ramsdell, National Oceanic and Atmospheric Administration (NOAA), Charleston Laboratory, USA has supplied parts of... |

| The experimental survey done, in august 2005, in coastal marine zone (0 - 20 m) of Zarzis showed the existence of numerous species of shellfishes of which Tricolia speciosa, Smaragdia viridis, Nassarius incrassatus, Cerithium vulgatum and Gibbulla umbilicaris are the most important gasteropods and, Pinctada radiate and Donax trunculus the main bivalves. The biomasses estimation, based on the method of swept area, in the studied zone showed that P. radiate is the most abundant species with about 20 000 tones, followed by C. vulgatum (7 645 tones) and T. speciosa (more than 1 000 tones). The Donax trunculus biomass is very low with only 13 tones. Finally, the abundance indexes distribution cartography permitted us to note that it varies from one species to... |
