Effects of White Spot Disease and Bio-Security on Shrimp Farming in Bangladesh

Effects of Inactivated Spot White Virus with radiation on Immune Parameters and Survival Rate of White ‎Leg Shrimp (Litopenaeus Vannamei)‎

The present resaerch was designed to evaluate the effects of Inactivated  Spot White Virus with radiation (gamma irradiant WSSV) on survival rate and immunity factors(THC, TPP, PO, SOD, POD) of white leg shrimp. The experiment was done in Bandar Imam Khomeini hatcheries from November 2013 until February 2014.  In this study, the survival rate and immunological parameters of shrimp that exposed ...

White Spot Viral Disease in Penaeid Shrimp – A Review

The global aquaculture of penaeid shrimp has grown rapidly during the past two decades. In 1998, world shrimp farmers produced an estimated 737 200 t of whole shrimp (this includes 530 200 t from the eastern hemisphere and 207 000t from the western hemisphere), a record 12% increase from the 660 200 t produced in 1997 (Rosenberry 1998, 1999). The shrimp farming sector suffered a serious setback...

White spot disease risk factors associated with shrimp farming practices and geographical location in Chanthaburi province, Thailand.

Over the past 2 decades, shrimp aquaculture in Thailand has been impacted by white spot disease (WSD) caused by white spot syndrome virus (WSSV). Described here are results of a survey of 157 intensive shrimp farms in Chanthaburi province, Thailand, to identify potential farm management and location risk factors associated with the occurrence of WSD outbreaks. Logistic regression analysis of th...

Effects of dietary astaxanthin on the immune response, resistance to white spot syndrome virus and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei

Three different experiments were conducted to study the effect of dietary astaxanthin on the immune response, resistance to white spot syndrome virus (WSSV) and transcription of antioxidant enzyme genes in Pacific white shrimp Litopenaeus vannamei. Each experiment included one triplicate treatment group (fed with 80 mg/kg astaxanthin supplemented diet) and one triplicate control group (fed with...
