Ciguatera and the Gambiers and Snorkeling
Contrary to popular belief, ciguatera isn’t caused by algae directly but by a handful of marine organisms that live on algae. The fish eat the algae and accidentally ingest the organisms which contain/produce ciguatoxin.
One of the organisms that produces ciguatoxin is …Gambierdiscus toxicus. Yep, that is correct GAMBIER, as in the Gambiers, as in the place we are right now. Gambierdiscus toxicus is a dinoflagellate (marine plankton) that lives on algae and produces ciguatoxins.
You might correctly assume that there is a lot of ciguatera in the Gambiers. Most of the fish are ciguatoxic.
This is bad for hunting and gathering and great for snorkeling. It is impressive to see how many parrot fish exist when no one is eating them and how HUGE the groupers get when they aren’t being eaten. The brilliant colors of parrot fish in schools is one of my favorite things about snorkeling here.
