(Energy Research HI Coden: Abstracts); TIC with FSYBA (Technical Information Country of Origin: United States Abstract: A total of 551 specimens of 48 species of potentially ciguatoxic fishes from Enewetak and 256 specimens of 23 species from Bikini, Marshall Islands, were tested for ciguatoxin by feeding liver or liver and viscera from these fishes to mongooses at 10% body weight (except for sharks, when only muscle tissue was used). The fishes are representatives of the following families: Orectolobidae, Carcharhinidae, Dasyatidae, Muraenidae, Holocentridae, Sphyraenidae, Mugilidae, Serranidae, Lutjanidae, Lethrinidae, Carangidae, Scombridae, Labridae, Scaridae, Acanthuridae, and Balistidae. The species selected were all ones for which toxicity can be expected, including the worst offenders from reports of ciguatera throughout Oceania; only moderate to large-sized adults were tested. In all, 37.3% of the fishes from Enewetak and 19.7% from Bikini gave a positive reaction for ciguatoxin. Because liver and other viscera are more toxic than muscle, the investigated. Most of the highly toxic species, including seven of the eight causing severe illness or death in the test animals (Lycodontis javanicus, Cephalopholis argus, Epinephelus hoedtii, E. microdon, Plectropomus leopardus, Aprion virescens, primarily piscivorous.; and Lutjanus bohar) are Major Descripters: *FISHES -- TOXINS; *TOXINS -- HEALTH HAZARDS Descriptors: BEHAVIOR; COMPARATIVE EVALUATIONS; DIET; ENVIRONMENTAL EXPOSURE PATHWAY; FOOD CHAINS; INGESTION; LABORATORY ANIMALS; LIVER; MARSHALL ISLANDS; METABOLISM; POISONING; PUBLIC HEALTH; QUANTITY RATIO; SENSITIVITY; TOXICITY 500392 percentage of positive reactions at the level which might cause illness in humans eating only the flesh of these fishes collectively would drop to 16.2 for Enewetak and 1.4 for Bikini. This level of toxicity is not regarded as high for Pacific islands, in general. Because ciguatoxin is acquired through feeding, the food habits of these fishes were
