Over 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 their mouths. Scientists do not believe that the invasion will ever be completely eradicated, but if the problem is recognized, steps can be taken to try to contain this invasion to a manageable level. Through education, fishing or hunting the species, and teaching other species to eat lionfish, there is hope that humans can gain control of these invasive creatures. Lionfish not only grow at an alarming rate, but they are also capable of reproducing at an alarming rate. rates in non-native oceans. An adult lionfish will measure between 12 and 15 inches in length in its native habitat, but it has reported alarming growth and has been caught at 18 inches and up to 20 inches off the coast of Florida. This species reproduces so quickly because the female lionfish produces gelatinous egg packets of 12,000 to 15,000 eggs each. These egg packets will break apart and drift in the current, allowing these eggs to disperse extremely quickly. These egg masses can float and separate 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 maintain the invasion cycle. In warmer climatic waters such as the Atlantic Ocean and the Caribbean, a lionfish can spawn every four days (Lionfish – Pterois volitans). Since the nutrient-rich waters of these oceans allow the lionfish to completely take control of the problem or solve it. Humans are only just beginning to understand exactly how this invasion occurs. are beginning to affect not only our oceans, but also the delicate reef life found there. Some affected countries are starting to see promising results with the decline of lionfish and the rejuvenation of reef life. Our oceans are not out of the woods yet, and this invasion is not even close to ending. This problem is created by humans and can only be controlled by human intervention. It is extremely important that everyone is aware of not only the lionfish invasion, but also the destructive consequences surrounding it. Through a variety of methods from public education to eliminating fishing/hunting and working with local predators, our ocean has a chance to survive..
