ciguatoxins of natural origin The first website selling Browse Catalog The Laboratory of Marine Biotoxins of the Louis Malardé Institute based in French Polynesia has developed a unique algal collection and bank of ciguatoxin standards of natural origine worldwide WELCOME TO PHYCONESIA



A pioneer in Ciguatera research

Established since 1967, the Laboratory of Marine Biotoxins of the Louis Malardé Institute has specialized in the study of ciguatera poisoning and its health impacts on Polynesian populations. Since this date, It has established itself as a reference in the field of ciguatera research, both in the Pacific region and internationally. 

Continued research

French Polynesia is the only Island State in the Pacific that currently has a permanent ciguatera research unit.

Technology watch

The strategy adopted by the laboratory to acquire the most efficient analytical tools is based on an active and continuous technology watch. 

A well-known expertise

The expertise developed by the Laboratory of Marine Biotoxins in the field of ciguatera research is internationally renowned. 

A unique bank of natural ciguatoxin standards, fruit of 50 years of research

The thorough toxicity screening of about a hundred of Gambierdiscus spp. strains has allowed for the identification of several highly CTX producing strains that constitute an innovative research material, most notably with regards to the mass production and purification of the algal ciguatoxins currently available in or bank of CTX standards 

  • Availability of pure toxins needed as standards for the detection of CTXs.
  • Asset for laboratories interested in acquiring analytical capacities for ciguatera monitoring.
