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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
