Florianópolis, Floripa to the locals, is the capital city of the state of Santa Catarina, in southern Brazil.

Data suggest that these anomalous w

Fish Killing Algae Fish-killing algae were well covered at ICHA17 with one key note address, 10 talks, 9 posters, and a dedicated round table event.

Investigation of recently isolated strains of the genera Azadinium and Amphidoma led to the identification of more than ten novel analogues of Azaspiracids (Bernd Krock, Urban Tillmann). STX analogues in G. catenatum were reviewed and s

Ability of giant clams to bio-accumulate ciguatoxins from Gambierdiscus cells Ciguatera Fish Poisoning (CFP) is a sea- food poisoning classically related to the consumption of tropical coral reef fish contaminated with ciguatoxins (CTXs). These polyether neurotoxins are pro- duced by dinoflagellates

Dead seabirds washed up on the beach may have been killed by eating contaminated sand lance. The way to find it out is to check the birds crop, to see if the bird
