Giant cannibal shrimp invasion growing
An invasion of giant cannibal shrimp into America’s coastal waters appears to be getting worse.
Researchers from the U.S. 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.
“And 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.
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.
They can be consumed by humans.
“They’re supposed to be very good. But they can get very large, sorta like lobsters,” Fuller said.
While they may make good eatin’ for people, it’s the eating the giant shrimp do themselves that worries scientists.
“Are they competing with or preying on native shrimp,” Fuller asked. “It’s also very disease-prone.”
To try to get those answers, government scientists are launching a special research project on the creatures.
“The Asian tiger shrimp represents yet another potential marine invader capable of altering fragile marine ecosystems,” NOAA marine ecologist James Morris said in a statement. “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.”
