Lionfish decimating tropical fish populations, threaten coral reefs
Date:7/17/2008

CORVALLIS, Ore. The invasion of predatory lionfish in the Caribbean region poses yet another major threat there to coral reef ecosystems a new study has found that within a short period after the entry of lionfish into an area, the survival of other reef fishes is slashed by about 80 percent.

Aside from the rapid and immediate mortality of marine life, the loss of herbivorous fish also sets the stage for seaweeds to potentially overwhelm the coral reefs and disrupt the delicate ecological balance in which they exist, according to scientists from Oregon State University.

Following on the heels of overfishing, sediment depositions, nitrate pollution in some areas, coral bleaching caused by global warming, and increasing ocean acidity caused by carbon emissions, the lionfish invasion is a serious concern, said Mark Hixon, an OSU professor of zoology and expert on coral reef ecology.

The study is the first to quantify the severity of the crisis posed by this invasive species, which is native to the tropical Pacific and Indian Ocean and has few natural enemies to help control it in the Atlantic Ocean. It is believed that the first lionfish a beautiful fish with dramatic coloring and large, spiny fins were introduced into marine waters off Florida in the early 1990s from local aquariums or fish hobbyists. They have since spread across much of the Caribbean Sea and north along the United States coast as far as Rhode Island.

"This is a new and voracious predator on these coral reefs and it's undergoing a population explosion," Hixon said. "The threats to coral reefs all over the world were already extreme, and they now have to deal with this alien predator in the Atlantic. These fish eat many other species and they seem to eat constantly."

Findings of the new research will be published soon in Marine Ecology Progress Series. The lead author is Mark Albins, a doctoral student working with Hixon.
