Final answer:
Ciguatera fish poisoning is caused by large predatory reef fishes like swordfish, shark, king mackerel, and tilefish, due to biomagnification of toxins from consuming smaller contaminated fish.
Step-by-step explanation:
Fish that can cause Ciguatera fish poisoning are typically large, predatory reef fishes that have accumulated the toxin through biomagnification. This occurs when they eat smaller fish that have consumed toxic dinoflagellates, such as those found in red tides. Over time, the toxins accumulate in larger predatory fish. Some fish associated with Ciguatera include swordfish, shark, king mackerel, and tilefish. The United States Environmental Protection Agency (EPA) advises pregnant women and young children to avoid these fish due to their high mercury content, which also biomagnifies. Instead, they recommend consuming fish low in mercury like salmon, shrimp, pollock, and catfish.
