Viral diseases
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2004)
Some viral infections are serious diseases of groupers causing heavy mortalities. In most cases, larval stages are the most susceptible stage. With the carnivorous nature of groupers, they can readily ingest viral pathogens ...
Establishment of preventive measures against viral nervous necrosis (VNN) in finfish hatcheries
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
The establishment of preventive measures against viral nervous necrosis (VNN) at the finfish hatcheries of SEAFDEC Aquaculture Department in Iloilo, Philippines, was instituted primarily to minimize the impact of the viral ...
Prevalence of economically-important viral diseases in wild shrimp (Penaeus monodon) in the Philippines
(Aquaculture Department, Southeast Asian Fisheries Development Center, 2005-03)
Prevalences of white spot syndrome virus (WSSV) and monodon baculovirus (MBV) were determined using polymerase chain reaction (PCR) as the detection method in wild black tiger shrimp (Penaeus monodon) collected from seven ...

Development of control methods of factors suppressing sustainable production of aquaculture species: Isolation of a piscine nodavirus from hatchery-reared sea bass Lates calcarifer in the Philippines
(Japan International Center for Agricultural Sciences, 2003)
The etiological study on mass mortality of larval sea bass Lates calcarifer cultured in the Philippines, demonstrated that the mortality was caused by viral nervous necrosis (VNN). Affected sea bass exhibited abnormal ...

Development for control methods for factors suppressing sustainable production of aquaculture species: Experimental transmission of piscine nodavirus-induced viral nervous necrosis to the orange-spotted grouper Epinephelus coioides
(Japan International Center for Agricultural Sciences, 2003)
Viral nervous necrosis (VNN) of larval orange-spotted grouper Epinephelus coioides has been recorded recently in the Philippines. The present study describes the pathogenicity of a piscine nodavirus (betanodavirus), the ...
