Course:CONS200/2020/Ecological impacts of lionfish invasion in Central America
The common lionfish (Pterosis volitans and P. miles), a midsized fish found in the Indo-Pacific Ocean, was documented in 1985 as a non-indigenous species off the coast of Florida. Since the 2000s, the fish is classified as an invasive species off the East Coast of the U.S. and the Caribbean, where its expanding populations continues to significantly reduce coral-reef fish communities and disrupt native ecosystems.
Several response plans have been created to address the problem at both regional and international scales. In the United States, the National Marine Fisheries Service released a National Marine Sanctuaries Lionfish Response Plan which applies within U.S. waters. Central American countries also independently developed plans, but without legal jurisdiction, management of lionfish invasion was limited. In 2010, the 24th General Conference of the International Coral Reef Initiative (ICRI) created an ad-hoc committee that designed a framework facilitating collaboration between existing programs and national stakeholders to better reduce the widening scope of lionfish impacts.
Because of its unique biological characteristics and behaviors, lionfish populations continue to persist in large numbers. Current management strategies include lionfish spearfishing (Usseglio, 2017), marketing for consumption and education campaigns.

Ecology of lionfish
Lionfish Range and Preferred Habitats
There are currently 12 species identified for Pterois genus, Andover lionfish, Spot-fin lionfish, Red Sea lionfish, and etc. Lionfish species spread widely all over the world, from Atlantic Ocean to Indian Ocean to Pacific Ocean, and it is native to Indo-Pacific as a predator. When talking about invasion, it is most invasive nowadays in the west Atlantic, Mediterranean Sea, and Caribbean Sea. Lionfish prefer to live in harbors and some turbid inshore areas, and they can also be found at the rocky surfaces, seaward edges of coral and so on.
Mode of Invasion and Traits Contributing to Spread
The mode of invasion for lionfish is the inhabitation of reef areas, which may cause the native species that live there move toward worse conditions and cause the decline for other species and reefs. Lionfish can spread in such a great success because there is much nutrient availability for lionfish, and they do not have specific predators. Data shows that lionfish has ability to survive and even reproduce in a brand-new environment, and they can also occupy a area in a short amount of time.
Other Factors Contributing to Spread
Lionfish have a wide range of preys to choose from their habitats. They can eat fished, mollusks, and up to 6 species in total. They are good predator with excellent hunting skills, especially when they use the currents to capture preys. Beside this, the lionfish were found in many different places, like reefs, rocky mountains, mangroves, and so on, which show that lionfish can adapt well in different temperature and salinity conditions, even depths range from 1m to 300m are their homes.
