A total of 259 specimens of 32 potentially ciguatoxic fish species from St-Barthelemy, Leeward Islands in the Caribbean sea were checked for ciguatoxin. It was found that flesh and viscera from 229 specimens belonging to 27 species (essentially bottom-dwelling species) were ciguatoxic. No correlation between toxicity and species size or diet was demonstrated since five of the six highly ciguatoxic species Seriola dumerili, Caranx latus, Caranx bartholomaei, Caranx ruber and Scomberomorus cavalla are large roving predators feeding mainly on fishes while the last species (Alphestes afer) is a benthic resident of very small size (less than 300 g) which feeds mainly on invertebrates. Small (less than 1 kg) benthic carnivorous fishes (invertebrate feeders), such as Bodianus rufus, Priacanthus arenatus, Mulloidichtys martinicus, Malacanthus plumieri and Halichoeres radiatus, are significantly ciguatoxic and play an important role in the transmission of ciguatoxin in the food chain. Other ciguatoxic species included large carnivorous fishes and the small surgeon Acanthurus bahianus. Furthermore, additional results suggest that most of edible benthic species from Saint-Barthelemy harbour ciguatoxin as well, though at an extremely low level. The ciguatera food chain in the Caribbean sea is therefore comparable with that described in the Pacific Ocean, except concerning small invertebrate feeders since their role in this chain is demonstrated for the first time.
对来自加勒比海背风群岛圣巴泰勒米岛的32种具有潜在雪卡毒素毒性的鱼类的259个样本进行了雪卡毒素检测。结果发现，属于27个物种（主要是底栖物种）的229个样本的鱼肉和内脏含有雪卡毒素。毒性与鱼的大小或饮食之间未显示出相关性，因为六种高雪卡毒素毒性的物种中，杜氏魣、宽体若鲹、巴氏若鲹、红若鲹和康氏马鲛中的五种是大型巡游捕食者，主要以鱼类为食，而最后一个物种（阿氏丝鳍鲷）是非常小的（不到300克）底栖鱼类，主要以无脊椎动物为食。小型（不到1千克）底栖肉食性鱼类（以无脊椎动物为食），如红西班牙鱼、砂普提鱼、马氏副金眼鲷、长鳍海鳗和辐射海猪鱼，雪卡毒素毒性显著，在食物链中雪卡毒素的传播中起重要作用。其他含雪卡毒素的物种包括大型肉食性鱼类和小型刺尾鱼巴氏刺尾鱼。此外，更多结果表明，圣巴泰勒米岛的大多数可食用底栖物种也含有雪卡毒素，尽管含量极低。因此，加勒比海的雪卡毒素食物链与太平洋描述的类似，只是小型无脊椎动物捕食者的情况有所不同，因为它们在这条食物链中的作用首次得到证实。
