There are four syndromes called<unk> , which share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops).  These<unk>  are filter feeders and, therefore, accumulate toxins produced by microscopic algae, such as dinoflagellates and diatoms, and cyanobacteria. For example, from algal bloom, e.g. Gymnodinium spp. or Alexandrium spp., etc., would have different toxins, or without toxins and just cause oxygen depletion.
The syndromes are:
Paralytic<unk>  (PSP)
Neurotoxic<unk>  (NSP)
Diarrheal<unk>  (DSP)
Amnesic<unk>  (ASP)
Shellfish poisoning
Scombrotoxic fish poisoning
Scombroid food poisoning
Strychnine poisoning
Coastal leucothoe poisoning
