问答题5. The lionfish is a tropical species native to the Indian and Pacific oceans. Noted for its vibrant colors, the lionfish was once a prized aquarium fish, especially in North America. However, its voracious appetite led to it attacking other fish kept in the same aquariums and resulted in many owners disposing of their lionfish in nearby waterways. While many lionfish died in the wild, they have found homes in the Caribbean Sea and Western Atlantic Ocean, where their numbers are exploding. They are consuming large numbers of fish in coral reefs and being general nuisances, so people are devising ways to get rid of them. Few fish actively hunt the lionfish, but the grouper is one. Yet the grouper is a popular food fish around the world, so fishermen commonly catch it. Some people have proposed enacting quotas on the number of groupers caught in areas with numerous lionfish. By doing so, the grouper population can increase, and then there will be more groupers to hunt lionfish. Fishermen are now being encouraged not to release any lionfish they catch but to kill them even if they have no plans to eat them. Divers with spear guns are similarly being asked to shoot any lionfish they find, especially those living in coral reefs. While the fishermen and divers may not kill large numbers of lionfish, they can actively reduce their numbers. People living in tropical areas are promoting the consumption of lionfish. The fish, which taste delicious, are considered a delicacy in China. By educating people in the United States and other countries about how good lionfish tastes, demand for the fish should increase, so more fishermen will start catching them. This should result in there being fewer lionfish in some regions. Directions You have 20 minutes to plan and write your response.
