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).
Shark finning
"The overfishing of sharks [has] serious effects for the entire marine food chain in some ecosystems. [...] [A] study found that removing sharks from a reef environment in the Caribbean had a trickling effect on other species. Without sharks, carnivorous fish that the sharks usually fed on thrived. The carnivorous fish, in turn, preyed on parrotfish that kept the corals clean. In time, the reefs changed from one dominated by coral to one overrun by algae."
