   The rate of the ichthyotoxic effect on immersed minnows within the temperature range of 10–30°C increases directly with the temperature (from 3 hours to 30 minutes), but the final titer of the ichthyotoxin is identical at both high and low temperatures.

   Ichthyotoxins are sufficiently widely present in the reef fish of tropical oceans, and with a sufficiently unpredictable occurrence, as to render the large-scale commercialization of snappers, groupers, jack, and other large, marketable fish a chancy business; in some iland groups, such as (it is claimed) Johnston and Phenix, very high percentages of species are toxic.

   Ciguatoxin (CTX) is the principal ichthyotoxin involved in a complex human food poisoning known as ciguatera, characterized mainly by neurological, gastrointestinal, and, in the most severe cases, cardiovascular disorders (6—10).
