And White House adviser Karl Rove now faces a sweeping investigation into his political activities on behalf of President Bush. We'll have a live report from the pentagon. Also tonight, new charges the Pentagon deliberately lied about the death of Army Ranger Pat Tillman in Afghanistan and the capture of private of Jessica Lynch in Iraq. We'll have that special report from Baghdad. strategy and tactics in Iraq after insurgents kill nine of our troops in a single attack. LOU DOBBS, HOST: Tonight, new questions about U.S. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED. “If we find differences, the next step will be to fine-tune the analysis to determine whether they are breeding here, have multiple populations, or are carried in from outside areas.9 Troops Killed in Iraq Military Cover-Up Charges Cheney Vs. €œWe’re going to start by searching for subtle differences in the DNA of Asian tiger shrimp found here – outside their native range – to see if we can learn more about how they got here,†USGS geneticist Margaret Hunter said in a statement. The latest study will look at the DNA of collected specimens. Tiger shrimp females can lay 50,000 to a million eggs, which hatch within 24 hours. Or the shrimp may be carried here by currents or in ballast tanks of marine vessels. Scientists don't know if there is a breeding population in U.S. Three hundred of those were recovered from waters off South Carolina, Georgia and Florida within three months.įarming of the giant shrimp ended in the United States, but they were caught again off Alabama, North Carolina, Louisiana and Florida.įive were caught off Texas last year, according to Tony Reisinger, country extension agent for the Texas Sea Grant Extension Service. In 1998, about 2,000 of the creatures were accidentally released from an aquaculture facility in South Carolina. Scientists are uncertain how many of the giant shrimp are in U.S. “Our efforts will include assessments of the biology and ecology of this non-native species and attempts to predict impacts to economically and ecologically important species of the Atlantic and Gulf of Mexico.†€œThe Asian tiger shrimp represents yet another potential marine invader capable of altering fragile marine ecosystems,†NOAA marine ecologist James Morris said in a statement. To try to get those answers, government scientists are launching a special research project on the creatures. "Are they competing with or preying on native shrimp," Fuller asked. While they may make good eatin' for people, it's the eating the giant shrimp do themselves that worries scientists. But they can get very large, sorta like lobsters," Fuller said. The shrimp, which can grow to 13 inches long, are native to Asian and Australian waters and have been reported in coastal waters from North Carolina to Texas. €œAnd they are probably even more prevalent than reports suggest, because the more fisherman and other locals become accustomed to seeing them, the less likely they are to report them,†said Pam Fuller, a USGS biologist. Geological Survey and the National Oceanic and Atmospheric Administration reported Thursday that sightings of the massive Asian tiger shrimp, which can eat their smaller cousins, were 10 times higher in 2011 than in 2010. ![]() An invasion of giant cannibal shrimp into America's coastal waters appears to be getting worse.
