ciguatera

 [se″gwah-ta´rah]
a form of fish poisoning, marked by gastrointestinal and neurologic symptoms due to ingestion of tropical or subtropical marine fish such as the barracuda, grouper, or snapper that have ciguatoxin in their tissues.

ci·gua·tox·in

(sē'gwă-tok'sin),
A marine saponin of unknown structure but with the empiric formula of C35H65NO8; the toxic substance that causes ciguatera.

ciguatoxin

/ci·gua·tox·in/ (se´gwah-tok″sin) a heat-stable toxin originating in the dinoflagellate Gambierdiscus toxicus as a pretoxin and and concentrated as the active form in the tissues of certain marine fish; it causes ciguatera.

ciguatoxin

(sē′gwə-tŏk′sĭn)
n.
A potent neurotoxin that is secreted by a dinoflagellate and can accumulate in the flesh of certain marine fish, such as grouper or snapper, causing ciguatera poisoning.

ciguatoxin

[se′gwätok′sin]
a heat-stable toxin originating in a dinoflagellate as a pretoxin and concentrating in active form in the tissue of certain marine fish (usually tropical reef fish), causing ciguatera in humans who eat the fish.

Herbivorous fish, feeding on the reef vegetation where Gambierdiscus is epiphytic, accumulate ciguatoxin precursors in their tissues.
Longer-term challenges of fish consignment restrictions include the changing regional risk profile of ciguatera resulting from climatic, oceanographic or other environmental impacts on coral reef health (Dickey and Plakas 2010) and the increasing toxic potential of smaller specimens of restricted trade species, or smaller fish more generally, because of increased harmful algal bloom events (Lechuga-Deveze and Sierra-Beltran 1995) and consequent ciguatoxin prevalence within the marine ecosystems (Dickey and Plakas 2010).
The causative toxins of its clinical manifestations are ciguatoxins (7).
