Report Asian Tiger Shrimp

Thank you for your participation!  By reporting Asian tiger shrimp, you help scientists better understand this species’ abundance and distribution along Georgia’s coast.  For assistance with species identification, please see the images below or send questions and/or a photograph to Todd.Mathes@dnr.state.ga.us

 


Attention: The first reported Asian tiger shrimp of 2014 was captured on the 30th of June.  The juvenile shrimp (approx. 4 inches) was caught in a small inshore creek using a cast net.  It's interesting to note that this report occurred about one month earlier than in previous years (i.e., in 2012 & 2013 the earliest reoprts were in late July or August).

In 2014, a new scientific artlcle was published about tiger shrimp titled 'Invasion of Asian tiger shrimp, Penaeus monodon Fabricius, 1798, in the western north Atlantic and Gulf of Mexico

Fuller et al Aquatic Invasions Vol 9 pp. 59-70-1.pdf

 

  Overview

Asian tiger shrimp (Penaeus monodon) are native to Indo-Pacific, Asian, and Australian waters, but are now found along the southeast and Gulf coasts of the United States. While small numbers of this non-native species have been reported in U.S. waters for over a decade, sightings have increased over the past few years.  Tiger shrimp are one of the primary species raised in shrimp farms around the world and can grow to be three times the size of our native shrimp.

The impact of non-native species on native fauna is often unknown.  Competition for food and habitat resources, predation, and transmission of disease may potentially impact local shrimp as well as other species.

  

Donate Asian Tiger Shrimp

We need your help!  Researchers are currently attempting to discover the origin of the tiger shrimp that are showing up along the Atlantic coast.  After being absent in Georgia for 20 years since its initial introduction from a South Carolina aquaculture facility, tiger shrimp were reported again in Georgia in 2008.  The source of this introduction is unknown.  Now the species can be found from North Carolina to Texas.

If you would like to donate tiger shrimp to help solve this mystery, please freeze it, record the date and location where the shrimp was captured, and contact Todd.Mathes@dnr.state.ga.us or call (912) 617- 0490

 

  • In 2013, thanks to the efforts of commercial and recreational fishers, GADNR processed 195 total tiger shrimp and contributed 50 tiger shrimp samples for genetic analyses.


Asian Tiger Shrimp Identification

Clearly, at sizes greater than 12", non-native tiger shrimp are easy to distinguish from our native shrimp based on their size alone. However, smaller tiger shrimp can be more difficult to identify.
