NOAA divers capture invasive lionfish in the Virgin Islands National Park

09.08.2010
Divers identified and killed a 15 cm long lionfish in Fish Bay along the southern coast of St. John, making this the fourth such capture and kill of the invasive fish in the Virgin Islands National Park.

The lionfish was first spotted July 15, 2010 and captured the following day within 10 meters of the original sighting. A team of divers and scientists from NOAA's National Centers for Coastal Ocean Science and the National Park Service were in the area collecting data aimed at evaluating the health of corals, fish and invertebrates in a ten-year long project funded by NOAA's Coral Reef Conservation Program.

This is the first time during the annual surveys the research team has sighted a lionfish. Governments across the Caribbean are concerned by the potential environmental impact of this species, which is multiplying rapidly across the region and consuming native fish at unsustainable rates in some locations.

"Lionfish pose a huge threat to the coral reef ecosystems of the U.S. Virgin Islands. The native fish populations are essentially defenseless in the face of this threat. And once established, lionfish are very difficult to control," noted Rafe Boulon, Chief of Resource Management for the Virgin Islands National Park and the Virgin Islands Coral Reef National Monument.

Native to the Indo-Pacific, Lionfish were first spotted in the US Virgin Islands off the coast of St. Croix in 2008. NOAA scientists with the National Centers for Coastal Ocean Science were the first to identify their first appearance in North Carolina and have been leading research and monitoring efforts since then. They have been in close collaboration with the Reef Environmental Education Foundation, scientists from Simon Fraser University, and the US Geological Survey to undertake critical research on lionfish biology, ecology, and environmental impacts.

In addition, NOAA is studying lionfish control strategies and has launched an "Eat Lionfish" campaign, which works with chefs, fishermen, and wholesalers to promote the development of a market for these fish. NOAA scientists have determined that a major fishing effort is required to reduce their numbers and mitigate their impact on reef ecosystems.

NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources. Visit http://www.noaa.gov.

Im Focus: Light-induced superconductivity under high pressure

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.

Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
