In the past 30 years since lionfish first appeared in the Atlantic Ocean, they have become a destructive nuisance. Lionfish species native to the Pacific and Indian Oceans are now invading the Atlantic and Caribbean Oceans, eating any fish that can fit into its mouth. Scientists do not believe that the invasion will ever be completely eradicated, however if the problem is recognized measures can be taken to try to contain this invasion to a manageable level. Through education, fishing or hunting of the species, and by teaching other species to eat lionfish, there is hope that humans can gain control over these invasive creatures. Lionfish not only grow at an alarming rate, but they are also capable of reproducing at an alarming rate. yew in non-native oceans. An adult lionfish will grow between 12 and 15 inches long in their natural habitat, but they have been reported to grow at an alarming rate and have been caught at 18 inches and up to 20 inches off the coast of Florida. This species reproduces so quickly because the female lionfish will produce gelatinous egg packets of 12,000 to 15,000 eggs a piece. These egg packets will break apart and drift in the current, allowing these eggs to spread extremely quickly. These egg masses can float and float away for about 25 days before tiny microscopic lionfish larvae (Lionfish – Pterois volitans) are born. These larvae will reach full maturity in less than a year, allowing them to reproduce and continue the invasion cycle. In warmer climate waters such as the Atlantic Ocean and the Caribbean, a lionfish is able to spawn every four days (Lionfish – Pterois volitans). Because the nutrient-rich waters of these oceans allow the lionfish to n...... middle of paper ...... completely gain control over the problem or solve it. Humans are just beginning to understand exactly how this invasion occurs as it begins to affect not only our oceans, but also the delicate coral reef life contained within them. Some affected countries are starting to see promising results with declining lionfish and rejuvenating coral reef life. Our oceans are not far from danger yet, and this invasion is not even close to being over. This problem was created by humans and can only be brought under control through human intervention. It is extremely important that everyone is aware of not only the lionfish invasion, but also the destructive consequences surrounding it. Through various methods including public education, removal of fishing/hunting, and working with local predators, our ocean has a chance to survive.
