Establishment of a Shrimp Disease Diagnosis Center and Survey of Georgia Coastal Waters For Viruses


PI: Marc E. Frischer (Skidaway Institute of Oceanography, Savannah, GA, USA)

Support: Georgia Sea Grant College Program (R/AQ-1-PD)

Timeframe: 9/1/96 - 2/28/98 (complete)

Project Overview:
The primary objectives of this development project were to implement and evaluate existing molecular methods for detecting and diagnosing White Spot Syndrome Virus (WSSV) and Taura Syndrome Virus (TSV). Once optimized, these methods could be used to assess the presence and distribution of WSSV and TSV in Georgia White Shrimp populations, and to assess whether the presence of shrimp aquaculture in South Carolina and Georgia would impact the health risk to South Atlantic Bight populations of White Shrimp.

Findings:
State-of-the-art molecular methods for diagnosing WSSV and TSV in shrimp were implemented at the Skidaway Institute of Oceanography. PCR and gene probe approaches were evaluated. Overall, available molecular methods appear to be useful for diagnosis of WSSV and TSV.

Preliminary results suggest that WSSV is present in native Georgia White Shrimp populations but that TSV is not. However, since so few shrimp were examined and were collected from limited locations (Skidaway River and Wassaw Sound), these conclusions must be regarded as preliminary.
