A study of the distribution of ciguatoxin in individual Caribbean fish.
Acta Trop. 1985 Sep; 42(3):225-33.AT

Abstract

Ciguatera toxins were extracted from the tissues of 36 poisonous fishes including 9 dangerous species collected in the Caribbean. Toxicity assays were carried out in mice and the distinctive symptoms of ciguatera poisoning were observed. In a single fish, ciguatoxin was found in the blood, flesh, gonads, gills, heart, skin and bones. The concentration was highest in the viscera and in particular in the liver, kidney and spleen. The ratios of the toxin concentrations of the liver or viscera to that of the flesh were high and varied with the species suggesting that the toxin is stored in different ways in different fish. Subcellular fractionation of liver cells revealed that most of the ciguatoxin was attached to cytoplasmic proteins and that some toxin was probably bound to the membranes.
