The relation between organic matter in sediment, shrimp density and polychaete presence in white spot syndrome virus (WSSV) affected shrimp ponds
03 / 2007 - unknown
WSSV has a wide range of hosts and vectors,including polychaetes. Organic matter concentration which is affected by shrimp culture management, can play an important role in WSSV disease development. Organic matter affects the shrimp health condition and many possible vectors that live in the sediment. Polychaetes In the pond may acquire the virus trough feeding. The objectives of this research are: 1.To evaluate the relationship between organic matter and the occurrence of the White Spot Syndrome Virus-positive (WSSV-positive) vectors in pond sediment. 2.To evaluate effect of organic matter on the transmission of WSSV from polychaete, as a potential vector, to shrimp and vice versa.
