雪卡毒鱼中毒（CFP）是一种环热带疾病，由摄入各种珊瑚鱼引起，生物积累藻类毒素。据报道，产生这些毒素的生物体，主要是Gambierdiscus属的腰鞭毛虫的分布和丰度与水温呈正相关。因此，人们越来越担心，与气候变化相关的气温升高可能会增加CFP的发病率。这一关切促使人们在18摄氏度至33摄氏度的温度下对六种冈比亚盘鱼的生长率进行了实验，并对加勒比和西印度群岛的海面温度进行了检查，以寻找能够维持冈比亚盘鱼全年快速生长率的地区。六种冈比亚盘鱼中有五种的最适温度为29 ℃以上。墨西哥湾南部的长期SST数据表明，在过去三十年中，海面温度>= 29摄氏度的天数几乎翻了一番（44至86）。为了确定如何在加勒比海的海洋表面温度和Gambierdiscus的增长数据与CFP的发病率，文献综述和统一的，全区域的调查（1996-2006年）的CFP的情况下进行。最高的CFP发病率在东加勒比海，那里的水温最温暖，变化最小。爱思唯尔有限公司出版
Ciguatera fish poisoning (CFP) is a circumtropical disease caused by ingestion of a variety of reef fish that bioaccumulate algal toxins. Distribution and abundance of the organisms that produce these toxins, chiefly dinoflagellates of the genus Gambierdiscus, are reported to correlate positively with water temperature. Consequently, there is growing concern that increasing temperatures associated with climate change could increase the incidence of CFP. This concern prompted experiments on the growth rates of six Gambierdiscus species at temperatures between 18 degrees C and 33 degrees C and the examination of sea surface temperatures in the Caribbean and West Indies for areas that could sustain rapid Gambierdiscus growth rates year-round. The thermal optimum for five of six Gambierdiscus species tested was >= 29 degrees C. Long-term SST data from the southern Gulf of Mexico indicate the number of days with sea surface temperatures >= 29 degrees C has nearly doubled (44 to 86) in the last three decades. To determine how the sea surface temperatures and Gambierdiscus growth data correlate with CFP incidences in the Caribbean, a literature review and a uniform, region-wide survey (1996-2006) of CFP cases were conducted. The highest CFP incidence rates were in the eastern Caribbean where water temperatures are warmest and least variable. Published by Elsevier Ltd.
