Invasive species among marine science subjects in Cayman Islands study abroad program

With a spiky fringe of venomous barbs and bold brown-and-white stripes, the exotic lionfish invaded Florida waters several decades ago and expanded its range widely from the Caribbean to New York. Native to the Indo-Pacific, the invasive species has no natural predators in this part of the world and readily feasts on small fish and shrimp.

UD students have the opportunity to observe these intruders — up-close and underwater — in a new study abroad program offered in the Cayman Islands through the School of Marine Science and Policy (SMSP). (more…)

Extent and Speed of Lionfish Spread Unprecedented

*Invasive Marine Fish May Stress Reefs*

Gainesville, Fla. — The rapid spread of lionfishes along the U.S. eastern seaboard, Gulf of Mexico, and Caribbean is the first documented case of a non-native marine fish establishing a self-sustaining population in the region, according to recent U.S. Geological Survey studies.

“Nothing like this has been seen before in these waters,” said Dr. Pam Schofield, a biologist with the USGS Southeast Ecological Science Center here. “We’ve observed sightings of numerous non-native species, but the extent and speed with which lionfish have spread has been unprecedented; lionfishes pretty much blanketed the Caribbean in three short years.” (more…)
