Supposedly there is such a thing as giant shrimp. Not just the jumbo sized one we buy at the grocery store. But these shrimp are more like lobsters in size and they are dark in colour with long appendages and legs. These huge creatures are invading, although we have told not to be alarmed.
The increase of the population of these gigantic creatures has increased 10 times in the past year. These findings come from The U.S. Geological Survey. In 2010, there were 32 of the crustaceans, in 2011, there were 331 reported. Another thing about these critters is that they eat each other, so their increase in numbers may not be that big of an issue unless they eat up the smaller shrimp that we consume. They have been seen in waters from Texas to North Carolina. Watch out east coast.
So what are these things being dubbed? They are a type of tiger prawn, which are served in restaurants everywhere. Texas Sea Grant Extension Service’s Tony Reisinger says that the shrimp are so large that they actually consume other shrimp. Cannibalistic Tiger Prawns are what we are seeing.
The massive Tiger Prawns are black and white striped ocean critters and have shown up on the Gulf of Mexico and the south-east coast. They weigh up to a quarter pound, and unlike their cousins, are 13 inches in length. That’s over a foot long!
Where did these animals come from? Like most other invasive species, they are native to Asia. The researchers in the field are worried that the Prawns may begin to gobble up other species of shrimp and they also fear the Prawns will spread disease to other shrimp. This could be a serious hazard to consumers.
The sudden and sharp increase in the giant prawn population bothers marine ecologist, James Morris. He says that the population indicates a true invasion. He is studying the influx at the National Oceanic Atmospheric Administration Center for Coastal Fisheries and Habitat Research.
No one knows how exactly the Prawn species was introduced into unites States’ waters, but carrying currents or breeding in local waters may have something to do with it. Although scientists say not to be alarmed, they are saying that the Tiger Prawn are not welcome in U.S. waters. The introduction of this species presents a potential upset for a very fragile ecosystem. We already have so many marine invaders.
Also, the numbers of the Prawn are probably higher than recorded. The more fisherman are likely to see them, the less likely they are to report them, so this puts a damper on research. The USGS is looking into the shrimps’ DNA to find out where it came from exactly and asks that anyone who finds one to report it immediately.
