Caribbean Sea
Marine biota in the region have representatives of both the Indian and Pacific oceans which were caught in the Caribbean before the emergence of the Isthmus of Panama four million years ago. In the Caribbean Sea there are around 1,000 documented species of fish, including sharks (bull shark, tiger shark, silky shark and Caribbean reef shark), flying fish, giant oceanic manta ray, angel fish, spotfin butterflyfish, parrotfish, Atlantic Goliath grouper, tarpon and moray eels. Throughout the Caribbean there is industrial catching of lobster and sardines (off the coast of Yucatán Peninsula).
Pigeye shark
Large and formidably toothed, the pigeye shark is regarded as potentially dangerous to humans, though it has not been implicated in any attacks. This species is caught infrequently on longlines and in gillnets, and is used for meat and fins. As a predator, though, the shark can accumulate ciguatera toxins produced by dinoflagellates within its tissues. In November 1993, some 500 people in Manakara, Madagascar, were poisoned, 98 of them fatally, after eating meat from a pigeye shark. This was the first recorded mass ciguatera outbreak caused by a shark, as well as the first with a significant death toll. The IUCN has listed the pigeye shark overall as Data Deficient, while noting that its rarity may render it susceptible to overfishing. In KwaZulu-Natal, South Africa, small numbers of pigeye sharks are caught in shark nets set up to protect beaches. The catch rate and the average size of sharks caught both decreased between 1978 and 1998, leading to concerns that the local population may be depleted. Thus, the IUCN has given this species a regional assessment of Near Threatened in the southwestern Indian Ocean.
