Precautions for amberjacks, barracudas, snapper, grouper, and
other carnivorous tropical fish:
Ciguatoxin
Carnivorous
tropical fish may eat smaller fish that have eaten algae carrying
ciguatoxin. Ciguatoxin is a natural toxin produced by microscopic
plants living in tropical waters. Ciguatera is a disease caused
by eating the fish, which have accumulated levels of ciguatoxin.
Larger fish can be thusly more toxic, from eating more fish that
have this toxin. Ciguatoxin is not destroyed by cooking.
Mussels, clams and oysters are also susceptible. Avoid eating
viscera including liver, intestines and roe of all tropical fish.
Symptoms
include:
- vomiting
- itching
- nausea
- dizziness
- hot/cold
flashes
- temporary
blindness
- hallucinations
- other
central nervous system dysfunction

these are only guidelines or basic information. Contact your local
extension service for more detailed information or the latest
